• , €200M, workplace tech: led the €200 million ($229 million) private-equity round for Paris-based Skello, which makes HR software for employers to handle tasks such as payroll, scheduling, compliance and employee communications.

Methodology

We tracked the largest announced rounds in the ������Ƶ database that were raised by U.S.-based companies for the period of July 4-10. Although most announced rounds are represented in the database, there could be a small time lag as some rounds are reported late in the week.

Illustration:

Within the region, U.K. startups gained significant share in Q2, raising more than $10 billion. That marked the third-largest funding quarter for the U.K. on record, and came in at less than $500 million below its peak quarter in 2021.

������Ƶ startup M&A activity also picked up in Q1 and continued that momentum in Q2, even as public-market exits stayed subdued.

Large rounds drive gains

Four companies raised venture fundings of a billion dollars or more last quarter, accounting for 25% of all startup investment in the region in Q2, ������Ƶ data shows.

Those billion-dollar-plus rounds were raised by an AI-centric group: -owned AI drug developer , which was spun out of ; green steel production manufacturer ; , which is developing robots for home and industrial applications; and , an AI lab founded by former DeepMind researchers.

However, most of the growth in funding year over year and quarter over quarter was driven by rounds of $100 million and over. The majority of funding — 65% —��went to a group of 42 companies that raised rounds of $100 million-plus. Sectors that stood out for these companies include�� biotech, quantum, financial services, AI labs, aerospace, semiconductor, robotics and energy.

H1 2026 up 50%

Funding to Europe-based startups in H1 was up 50% year over year to total $42 billion, ������Ƶ data shows. Still, the region’s startup investment for the first half of the year remained well below the 2021 H1 peak, when VC funding in Europe totaled $60 billion.

It’s also drastically lower than the $392 billion raised in North America’s record-setting H1, with that region’s funding up 158% year over year.

Europe’s funding deal count subsided last quarter, but mostly at the seed stage. Late-stage rounds were up a bit, while early-stage deals dipped slightly year over year. (It’s worth noting, seed stage rounds are often added to the ������Ƶ data set after the close of the quarter, so those numbers will increase over time.)

UK momentum builds

The United Kingdom widened its venture-funding lead last quarter, as startups based in the country raised $10.4 billion — not far from the peak in 2021 at $10.8 billion.

The region’s No. 2 startup market, Germany, trailed with $3.2 billion raised by its startups in Q2, and France followed in third place with $2.4 billion. Sweden was Europe’s fourth-largest startup market last quarter, with its companies raising $2 billion.

������Ƶ data shows funding to Europe’s AI-focused companies reached more than $10 billion in Q2 — the largest quarterly amount so far — but slightly below the Q1 percentage, when those companies raised more than half of the region’s startup investment.

By stage

Europe’s late-stage funding totaled $12.1 billion in Q2, up 90% year over year. Large Series C and D rounds were raised by Germany-based robotics developer Neura Robotics; Netherlands-based , which makes inspection tools for semiconductor manufacturing; U.K.-based quantum computing startup ; and Germany-based satellite launcher .

Early-stage funding reached $8.6 billion across 250-plus Europe-based startups last quarter, ������Ƶ data shows. Large Series A and Series B rounds were raised by London-based Isomorphic Labs, London-based AI self-learning lab , Germany-based fusion energy company , London-based semiconductor developer , and London-based quantum processor provider .

������Ƶ seed funding totaled $3.2 billion last quarter, with a billion dollars of that raised by just one company: Ineffable Intelligence.

Other large seed rounds were raised by , a London-based AI lab for science; Italy-based autonomous driving technology producer ; and Stockholm-based defense tech company .

M&A increase

While IPO activity for ������Ƶ startups was muted, M&A showed strong momentum following increased activity in Q1. A total of 154 Europe-based, venture-backed companies were acquired for a cumulative $11.5 billion or more in Q2, ������Ƶ data shows. That includes three companies acquired for more than $1 billion each in biotech, industrial AI and micromobility.

Looking ahead

������Ƶ startup investment has now steadily increased since the fourth quarter of 2024, with increased momentum in the just-ended quarter, driven by larger rounds of $100 million and over. The region’s startup ecosystem shows particular strength in deep tech and financial services as well as the formation of new AI labs, and M&A activity has fueled liquidity for the next batch of startups.

Now the question remains: Will it be enough to keep Europe competitive with the frontrunners, the U.S. and China?

• North American Startup Funding Shattered Records In First Half Of 2026, Driven By AI

Methodology

The data contained in this report comes directly from ������Ƶ, and is based on reported data. Data is as of July 6, 2026.

Note that data lags are most pronounced at the earliest stages of venture activity, with seed funding amounts increasing significantly after the end of a quarter/year.

Please note that all funding values are given in U.S. dollars unless otherwise noted. ������Ƶ converts foreign currencies to U.S. dollars at the prevailing spot rate from the date funding rounds, acquisitions, IPOs and other financial events are reported. Even if those events were added to ������Ƶ long after the event was announced, foreign currency transactions are converted at the historic spot price.

Glossary of funding terms

Seed and angel consists of seed, pre-seed and angel rounds. ������Ƶ also includes venture rounds of unknown series, equity crowdfunding and convertible notes at $3 million (USD or as-converted USD equivalent) or less.

Early-stage consists of Series A and Series B rounds, as well as other round types. ������Ƶ includes venture rounds of unknown series, corporate venture and other rounds above $3 million, and those less than or equal to $15 million.

Late-stage consists of Series C, Series D, Series E and later-lettered venture rounds following the “Series [Letter]” naming convention. Also included are venture rounds of unknown series, corporate venture and other rounds above $15 million. Corporate rounds are only included if a company has raised an equity funding at seed through a venture series funding round.

Technology growth is a private-equity round raised by a company that has previously raised a “venture” round. (So basically, any round from the previously defined stages.)

Nonetheless, amid a period of soaring , rising EV adoption rates, and accelerating progress in fusion and other fields, cleantech investment activity isn’t slowing down.

In the first half of this year, investors poured $15 billion into seed- through growth-stage rounds for companies in ������Ƶ cleantech, EV and sustainability-focused categories. That puts funding on track to slightly exceed the 2025 tally, which was the lowest in several years.

On a quarterly basis, funding is also on the rise. Around $8 billion went to companies in cleantech and related categories in the second quarter of this year, the highest quarterly total since 2024.

Even taking into account recent gains, however, cleantech funding remains far below its former peak in 2021 and 2022. Given that overall venture funding has risen with the AI boom, cleantech also accounts for a smaller share of total investment.

Where funding is concentrating

That’s not to say megarounds aren’t getting done in the sector. A look at the largest funding rounds of 2026 paints a varied picture of where capital is concentrating.

Stockholm-based green steel producer scored the largest financing of 2026, securing $1.6 billion in a round led by Swedish asset manager . Stegra plans to use the money to complete the construction of its large-scale steel plant.

The next-biggest round went to , a -backed startup that has been generating buzz and reservations for a flagship electric pickup starting at around $25,000 that can be converted to an SUV. Troy, Michigan-based Slate raised $650 million in Series C funding in April and plans to deliver its first trucks to customers later this year.

The third- and fourth-largest financings were fusion deals. The latest of those went to , which raised $465 million in a June Series G funding to go toward building a fusion power plant. The -led round set a $15.5 billion post-money valuation for the Everett, Washington-based company.

A few months earlier, fusion startup picked up $450 million in Series A funding led by . The San Francisco-based company, formed around a fusion breakthrough at , plans to build the world’s most powerful laser to further its goal of grid-scale energy production.

For a broader view of where large financings are concentrating, below we put together a list of 10 of the largest cleantech-related rounds this year.

Under the circumstances, the space looks underfunded

While sums going to cleantech-related startups aren’t tiny, looking at total investment tallies does leave one with the impression that the space looks underfunded.

After all, energy is a growth sector, and clean energy is leading the way. The forecasts the share of renewables and nuclear in the world’s power mix will rise to 50% by the end of this decade. At the same time, global power demand is set to grow by more than 3.5% per year on average over the rest of this decade.

Exits of venture-backed companies are also happening, another source of encouragement for startup investors. The most recent IPO in the space was geothermal provider , which went public in May, raising $1.9 billion. The Houston-based company had a recent market cap around $8.6 billion.

On the nuclear power front, , a developer of small modular reactors, carried out its own Nasdaq IPO in April, raising $1 billion. The Rockville, Maryland, company was recently valued at a little over $5 billion.

Looking ahead, it’s not far-fetched to see myriad factors that could power clean energy, sustainability and EV sectors higher. For clean power in particular, the voracious energy demands of AI are certainly a catalyst to consider. We’ll stay tuned to see if growing energy demand ultimately translates into greater startup investment.

This is a weekly feature that runs down the week’s top 10 announced funding rounds in the U.S. Check out last week’s biggest funding deal roundup here.

U.S. startups announced sizable funding rounds at a steady clip during a truncated holiday week, with energy and AI leading the way.

Methodology

We tracked the largest announced rounds in the ������Ƶ database that were raised by U.S.-based companies for the period of June 27-July 2. Although most announced rounds are represented in the database, there could be a small time lag as some rounds are reported late in the week.

Illustration:

founded after departing as CTO in 2022. The firm invests in companies rebuilding the physical economy. As Schroepfer and his partners at the firm see it, surging demand for AI, power and industrial capacity is creating a once-in-a-generation opportunity to rebuild the physical economy — from energy infrastructure and advanced manufacturing to materials and robotics. And as AI makes software cheaper and easier to create, the competitive advantage increasingly shifts to the hardware, energy systems and supply chains that underpin it all.

Key to starting the fund was Schroepfer’s experience building out the infrastructure to support Meta’s business. “I could see the trends coming. We’re going to need all the compute,” he said. “I don’t know where we’re going to get the power, so it’s going to create this massive supply-demand crunch.”

Gigascale raised its first institutional fund this month, a $250 million investment vehicle. The firm has already made more than to date.

Schroepfer’s partners at the firm are , previously an investor at climate-focused investor , and , previously at .

Before raising the fund, the firm made 22 investments funded by Schroepfer’s family office in order to prove the model. At the time, the broad perception was you could not make money investing in the hardware layer.

‘Not software with higher capex’

Gigascale invests at pre-seed through Series A with some later-stage investments. Its check size is anywhere from $1 million to $10 million.

Hardware businesses are not the same as software businesses. “It’s not a software business with higher capex,” said Schroepfer. “The failure modes are very different. The way you plan and test and iterate, and what you understand is very different.”

In our conversation, we spoke about an array of topics, including energy as a major investment focus, his learnings from running Meta, why now is a great time to build a hard-tech company and what excites him about the IPO.

Gené Teare: What is Gigascale’s thesis?

Mike Schroepfer: It’s really simple. We are backing companies that are rebuilding the physical economy. This is how things are powered, built, moved, manufactured and how people are fed.

The belief is there is a confluence of technological changes that are bringing new products and new companies to market that are better, faster, cheaper than what’s out there. This is the biggest part of the economy.

Another way to say it is that we think the future is atoms, not bits, and it’s a really exciting time to be building these companies.

What did you see that made you decide to set up the fund in 2023?

Schroepfer: A lot of the tech trends I have been part of — from the web transition when I worked on Firefox, to the early web infrastructure at , to the mobile transition in the early 2010s, to founding the Facebook AI Research Lab in 2013, well before ChatGPT — were looking at the very shallow part of exponential curves. These technological changes did not seem that prevalent yet, but they were on this massive upswing.

I saw the same set of curves in solar cells, batteries and electrolyzers. They were all going through massive exponential cost downs, and at the same time a massive increase in demand. We had electric vehicles showing up, onshoring and manufacturing, and this was pre-data centers. I knew compute demand was going to grow. Where are we going to get the electrons to fuel all of this? It’s going to create an immense supply chain crunch.

Demand and supply were converging at the same time to create massive tailwinds. It just felt like this opportunity to rebuild the entire physical infrastructure in a way that our kids are happy about. Meaning, the new solution wins because it is cheaper, better and faster.

The other co-benefit it brings along with it is that because it is simple and cheaper, it is also less polluting, so it doesn’t hurt humans. I can build a solar farm way faster than I can build a gas power plant. I can live next to a solar farm and get zero pollution. I do not want to live next to a gas plant.

What I understand about the firm is that you are very focused on energy specifically. Is that a misunderstanding?

Schroepfer: It is probably the single biggest area that we invest in. A large chunk of our portfolio is energy. It is a $2 trillion market and it is the place where I think all the disruption is happening. But we also invest in industry, including materials from neodymium to copper, production and recycling, to a lot of AI in the physical world. That includes everything from how I use AI to make my house more efficient with , to how I build power-efficient AI inference chips with .

Then there is the built environment, in terms of buildings, and a little bit in food. We do a little bit in everything, but if you look at our portfolio, the two biggest hunks are really energy and AI in the physical world.

When do you think Silicon Valley woke up to the focus on the physical world?

Schroepfer: In the broad consensus, it happened recently — in the last six to 12 months. There were some folks who were looking at it early, but I think the broad consensus has just happened recently.

The other thing that I saw is, if AI is going to make software nearly free to write, then I think software businesses might be challenged, and the moat moves to the hardware. The game becomes: How do I get the infrastructure built to have a better AI? That is mostly an infrastructure hardware problem, less of a software coding problem, and that is going to filter through a lot of businesses.

When I started, frankly, three years ago, I had many people — I am thinking of someone sitting in my office — saying, “don’t do this.” All the money is in software. You can’t make money in hardware.

It doesn’t hurt that , , , and are now household names of companies that have had massive valuation runs because they are such a core part of the physical economy. I used to use Nvidia as my example, but now I can use SpaceX. Talk about a company in the biggest market that is running away from the competition. It’s a really hard company to compete with.

How should we understand the energy needs in the U.S.?

Schroepfer: We’ve been at relatively flat demand over the past 20 years or so, meaning each year that goes by, we don’t need much more power, close to 0%. We are now growing at at least a few percent a year.

Something has gone from almost no growth to relatively high growth. You’ve got hundreds of gigawatts of data centers planned to be built over the next five years alone. That doesn’t count EV charging stations and electrification of homes and factories. It’s a massive supply-demand imbalance right now, and building power takes a long time. If you’ve got to build a power line, if you’ve got to permit a gas power plant, these things take years, not months. It has created massive demand, but everyone wants compute yesterday.

Meta has used tents instead of buildings for their servers because cutting out the time erecting steel for the building gets them compute faster. Everyone is thinking about how to get power faster and how to get compute faster because, again, it’s a competitive advantage when infrastructure is the moat.

Which technologies are you focused on in the shorter term, and then the longer term?

Schroepfer: We have companies deploying things now. In the power crunch, one of the big problems is that the demand for power swings much more widely than it used to. It used to be fairly steady. Now you have big training runs, you have solar that comes on and comes off, and you need a shock absorber to dampen the power or deal with three or four days of clouds or no wind, if you’re depending on renewables.

is a company that has a new kind of battery that lasts for four days. You charge it up, and it’s there for 100 hours. In any event where a power plant is offline or the sun is not shining, Form Energy is there. Utilities think of this instead of building a gas power plant. There are these gas power plants called peakers, which you only turn on when you really need them. They sit there all the time, and then you fire them up in these intervals. Instead of doing that, which is very expensive, you have this Form Energy battery: zero emissions, much cheaper to operate, and built from the ground up for utilities using a totally different technology. They are going to be deploying batteries this year, as an example.

Going in a different direction, the entire supply chain for how we get electrons to a building. I’m going to build a new data center, and I have to hook it up to the grid to get electrons there. There is all this equipment in the middle called power transformers, these big green boxes or big metal boxes. It’s literally 1930s technology. We haven’t changed much since then. They are back-ordered for years now because they are these exquisite hardware machines.

There is a new company, , that said, “wait a second, we’ve been shipping this new generation of technology called solid-state power electronics in electric vehicles — the Model 3, Model Y, and more — for millions of units a year, with very fast ramps. We’re taking that same technology and putting it on the grid.” We’re replacing this 1930s technology with 2020s technology. It’s more efficient, it’s a third the size and, most importantly, they’re going to start shipping lots of units next year. They’re building their factory right now. In 2027, they’ll be shipping lots of these Heron Link units.

A little bit further out, we have a company called that said, “we’ve got about 10 terawatts, which is an immense amount of power, in the Southern Ocean in waves sloshing around with nothing else going on down there. If we can harness that, it is an untapped resource.”

They’re building autonomous buoys that float in the ocean. They bob up and down and turn that wave motion into electricity. Then they use that to power, on the buoy, a compute node to do AI inference and use to send the bits back. They’re kind of exporting electrons via tokens in the Southern Ocean.

They’ve been testing off the coast of Portland, and they’re going to deploy their first units next year. People have talked about data centers in space. My big pitch for this company is that it’s 100x cheaper to put a ton of capacity in the open ocean than it is to put it into space. If you think data centers in space are a good idea, you might want to look at the ocean.

Then you can think about , a company in El Segundo, California. They are building a compact, next-generation microreactor, or nuclear reactor. You can think of it as something you put on a truck or on an airplane, and it can run and power something for five years straight. Instead of, in a remote region in Alaska or on a Pacific island, doing what they do now, which is shipping diesel fuel there to run a diesel generator 24/7, you install one of these boxes, and it produces power for five years before it needs refueling. Most importantly, again, you would not want to sit next to a diesel generator while it’s operating. It has very toxic emissions. This thing has no emissions. It’s good for humans, and it’s actually going to be cost competitive with those things. Those are some examples of things we’re doing in the power sector that I think are really affecting the future.

Is there an unlock in this industry that has made development cheaper and faster at this moment in time?

Schroepfer: The analog I’d use is from computing. We used to build mainframes, these big building-sized computers. Then we had minicomputers that were still really big. This is the motherboard for the first server we designed at Meta that we deployed in 2011, called Freedom. It was a Type 1 server. It was the web server.

I installed millions of these, maybe tens of millions. I don’t even know how many. They’re all the same, every single one of them. They go in a pizza-box-size thing that goes into a rack in a building. That building comes in four units. Each of those is the same. That building is next to another building, which is exactly the same. We build four of those on a site. They all look the same. I did that in 17 places around the world. They all look the same.

The technique we use to make things cheap is mass manufacturing. Everything in your life that has gone down in price or improved in price-performance is mass manufactured: your iPhone, the servers and data centers. They’re all the same. They’re mass manufactured.

The world is full of custom, bespoke stuff that’s wickedly expensive.

In the power grid, for example, all of the stuff I talked about, you custom order it. I want a transformer. I do engineering design. I send it off to someone. Four years later, a truck shows up with the crane and all the rest of it. That’s inherently expensive and gets more expensive every year. Everything that is custom gets more expensive every year, so I think the biggest thing we’re seeing is this move to things that are mass manufactured.

Solar panels are mass manufactured. Batteries, the things that go in your phone or in your electric vehicle, are 99% cheaper than they were 20 years ago. That’s because we manufacture them at a massive scale. Every time you double the size of manufacturing, you get a 10% to 20% reduction in cost, and there are so many other problems like that.

In this case, the power electronics, the transformer, are all special-purpose. Heron Power is going to make the same box for a data center, for an EV car charger, and for a solar farm. It’s the same box. No changes. That’s how we’re going to get a cost curve down for these things. That is the most exciting trend underneath this: the idea that generalization and mass manufacturing of things allows you, year over year, to reduce costs.

When you’re competing in the power industry, fossil fuel costs have been basically stagnant. They go up and down a little bit, but if you average them over 50 years they are not on a cost-down curve. It doesn’t get cheaper to get oil out of the ground. My competition is flat, and I’m getting 10% to 20% cheaper every year. That’s a great business to be in. That’s the big trend behind all of this. We saw it first in solar and in batteries, but it enables a whole bunch of other things in other industries, like power electronics and more.

Are we at this time very dependent on China for mass manufacturing?

Schroepfer: A lot is coming from China, but I visit a factory a week in the United States that is getting spooled up with robotics, with really smart founders from and SpaceX. It turns out that when you start in 2026, you can build a much more efficient, much faster factory. You can use modern technologies.

Right now, China has the industrial base, and we’ve let it go. But I think we have a shot at rebuilding it in the United States, and I see brilliant founder after brilliant founder running at this problem inside the United States every day and every week.

It’s one of the reasons I started this firm, too. I think we have a shot to rebuild that industrial base in a next-generation set of technology. Just like regions around the world that didn’t have landlines went straight to cellphones, we’re going to go straight to fully automated robotic factories with 3D printing, laser milling and the latest technology set. It is not going to be a cut-and-paste of what happened in China, but a next-generation set of technologies that allow the U.S. to be self-sufficient in what we’re doing.

We’ve seen new techniques. As an example, rare earths were something no one ever talked about. Neodymium is this rare earth material that is key to making a magnet. Who cares about magnets? Well, magnets are in every electric motor in anything. Anything that has an electric motor, you care about magnets. Almost all the neodymium is made in China, and it is made in this very polluting, dangerous process. You do not want to visit one of these factories with fluorinated gases — it’s awful.

We’ve got a company making neodymium in Alameda, California. That is not an easy place to permit polluting things, which is fine for them because their process doesn’t pollute at all. It’s very simple. It’s two reactors. I walked around the facility. You don’t need any protective gear. Because it’s so simple, they are cost-competitive with Chinese imports.

To their customers who are saying “I’m trying to make magnets,” they’re saying “great, I will sell you neodymium. I have it. It’s cost-competitive.”

Everyone is excited, but the thing we’re whispering in the background is, it’s also not polluting. This is how we’re going to win. It’s not a cut-and-paste of that technology over here, but saying, “How do we approach this in a way that’s simpler and cheaper, and then likely cleaner as well?”

We’re doing the same thing in copper. We’ve got a whole bunch of bets in different kinds of materials where I think we can do it better in the U.S. We’ve got a company, , in South Carolina that’s doing this for copper recycling. We’re doing it in cement manufacturing. There is a whole variety of opportunities. I don’t have enough time to meet all these entrepreneurs.

We talked a lot about some of the companies in the energy sector. What are the other areas of investments that you’ve made that you’re excited about?

Schroepfer: I mentioned this a bit, but worth going a little deeper on is applications of AI to the physical world. I talked about one: Fractile, which is building a next-generation AI inference chip that’s much more power efficient.

Another example is a company called , which is using AI to put a simple piece of hardware on a power line, on both sides of a power line, to detect if there is a fault in that power line that might be causing a fire. The idea is that if you detect that fault sooner, you can prevent the fire before it’s a problem instead of waiting for it to happen and then having to respond. Using AI plus hardware to figure these things out is another example of that.

We have another company called that’s using AI to help with the nuts and bolts of how people make transactions to build energy projects. There is a lot of due diligence work and other things that need to happen. You can build, very much like for legal or for doctors, these vertical AI companies. This is a vertical AI company for energy developers. There is a lot to happen there.

Then is doing industrial automation with robots, using next-generation models to train robots to be more effective in factory environments, back to my point of how we are going to do this in the U.S. with advanced robotics. I think AI for the physical world is a big area.

I talked a bit about materials: neodymium, copper. We have a company called that’s making clean chemicals. Those would be the big areas I would highlight.

I know there are a lot of investors that you partner with or work with that are similarly focused in this area.

Schroepfer: The thing that’s been most interesting is that there is a set of folks who have been doing hard tech or climate for a while, and they are great partners of ours, from to to to many others. But what’s been interesting to me is the generalist firms coming in. A very common co-investor for us is , , or . We’re seeing them come in large amounts, because they’ve seen the economic opportunity here.

What did you learn from spending 14 years at Meta?

Schroepfer: I learned a few things. When I joined in 2008, the company had fewer than 100 million users, was not profitable, and had about a 150-person engineering team. We relied on outside parties to do all the hardware work. We were leasing data center space.

Over the next 14 years, we grew dramatically in users and profitability and in the size of the team. But we also moved into the physical world. As I showed you the server, we built our first data center in 2011. I built 10 million-plus square feet of data centers in 17 places all over the world. We then moved to consumer hardware, so we built the smart glasses, the Oculus Quest VR headset, and the Portal. Then we moved into AI research with the Facebook AI Research Lab in 2013.

That shift into the physical world brought a lot of really humbling lessons. There were a lot of times where stuff just went wrong. At the very first data center, I remember touring it under construction, and we had wood blocks on the loading dock because they had graded the loading dock wrong, so the trucks couldn’t back up and unload properly.

It’s this new, awesome, state-of-the-art data center with a free-air cooling system, and we got wrong the thing that every in the country has five of. It’s a million small challenges.

This is the thing I bring to the founders that I see: having learned how to build stuff in the physical world builds an appreciation for the risks and scale, and for how you need to emphasize speed and learning rate.

People learn the wrong lesson. They think hardware means spending a lot of time designing on paper. Wrong lesson. You have to get out there because you don’t know which part is going to blow. You have to get out there and learn as fast as you can and as cheaply as you can, so that when you’re in mass production, you’re not learning things, you’re just repeating.

That lesson, from data centers to consumer hardware, matters. When we build consumer hardware, you spend 18 months building this exquisite pair of glasses or this exquisite headset, but before you sell it, you have to do this drop-test thing, where you literally say, what happens when someone takes it out of the box at home and drops it on the ground? If it breaks, they return it, and we eat the cost. So you sit there and drop this thing with high-speed cameras over and over again to make sure it will survive a drop from head height. You don’t think of these things when you’re designing it. You have to make sure someone can drop it and it’s fine, or spill some wine on it and it’s fine.

Those problems in the real world, plus the challenges of building an executive team and scaling an organization, are the fun part of my job: working with our founders and having their back when things are tough, when they need to recruit someone, or when they’re running into a challenge in the real world, because I’ve seen it. I’ve seen it all.

What’s your reaction to the SpaceX IPO?

Schroepfer: I’m honestly pretty excited about it, because we have a lot of SpaceXers in our portfolio. I have a lot of friends who are alumni or work at SpaceX. Having more people in the world with the financial resources to work on audacious engineering projects is going to be really good.

I think it’s also a lesson in building and hardware. How many companies can land rockets the way SpaceX can? They’ve been doing this for a decade, so they have a very large technical moat in terms of what they’re able to deploy in the world. Starlink is another example. Everyone is racing to catch up. If you’ve ever used Starlink on an airplane, you don’t ever want to be on an airplane without Starlink. It’s hard to describe other companies that have such a singular product as SpaceX. I think it’s exciting that the markets are rewarding that. I can’t wait to see what SpaceX alumni do next.

I imagine there’s going to be a lot of company formation coming out of that IPO.

Schroepfer: It’s going to be an exciting five years. I met you after I started my first company in 2000 and sold it off. We looked at starting another company, and then I worked at and Facebook, so I’ve been through a couple cycles of this. I think it is the most exciting time to start a company, in terms of the capital available, the AI tools available to you, and the physical tools to build things quickly in the physical world. It’s the bet I made: I think this is the most interesting time to be building new companies. That’s the smaller version of why I did this. I think this is the time. This is the thing to be doing.

“Silicon Valley has done very well with software, but while software was eating the world, they forgot about silicon,” Barrett told ������Ƶ News in an interview.

The firm recently closed a $475 million fund focused on investing in deep-tech startups at seed and Series A. In the decade-plus since its founding, it has built its investment thesis around the idea that breakthroughs in science and engineering — not just software — would create the next generation of valuable companies.

With demand surging for compute, semiconductors and energy, Barrett argues the rest of the industry is now catching up. “We’ve been at it for more than a decade,” he said. “In recent years, as AI is eating software, people are scrambling back to recognize that the energy, semiconductors and infrastructure they operate on all need capital too. We’ve been operating in that regime for a very long time.”

Barrett is originally from Australia and came to Silicon Valley in the 1980s. He’s been coding for 50 years, he said, after developing an early and deep respect for science and engineering as the child of two engineers. His childhood was steeped in punch cards, draftsmen and drawings of control systems and machinery, he said.

“Science lets you follow breadcrumbs from prehistoric plumage to semiconductors. One principle can be applied somewhere orthogonal and create extraordinary value,” Barrett said in a lengthy interview with ������Ƶ News.

Barrett went on to found video game developer , joined to build the entertainment browser acquired by , and was subsequently CTO at prior to co-founding Playground Global in 2015.

Playground Global operates a lab in the former Palo Alto Research Building in Palo Alto, California. The location hosts 350 people, including those working at its portfolio companies and others with adjacencies working from the lab.

On a recent visit to the warehouse, I saw various models of robots, materials for aerospace construction, and a model of building powerful lasers to increase the speed of semiconductor manufacturing. The quantum computing startup , a Playground portfolio company, moved in when it had three employees and moved out when it reached 90.

The firm has four general partners. Along with Barrett, they are , the former CEO of and who architected CPUs at Intel that helped computing take off at scale, and who joined the Playground team last year as a general partner specializing in semiconductors; , who has made many investments in biotech, including ; and co-founder , who led the investment in .

What follows are highlights from a wide-ranging interview with Barrett that covered topics including sovereign technology, the need to invest in companies that operate on the physical plane, and why he believes putting data centers in space is stupid.

This interview has been lightly edited for clarity.

Gené Teare: What is the thesis for Playground Global?

Peter Barrett: It is about reducing new results in science and engineering into commercial and societal value. That means operating at the boundary between computation and the physical world. We are very interested in new capabilities of computation driving civilization forward, and that inevitably means operating in the same physical plane that we live in.

We’re seeing in our data a huge amount of funding going into space, semiconductors and robotics. It seems as if the whole venture industry has pivoted to this much broader array of companies. Do you see that as a good thing?

Barrett: We lost a lot when people weren’t investing in things that strike us as important. It is good that there is capital chasing the things we care about and that have real consequence.

You can’t spin up a deep-tech practice overnight. You still need domain expertise. You still need to understand why investing in nuclear reactors is good, and why data centers in space are preposterous.

Silicon Valley hasn’t been very efficient with much of the capital it’s deployed over the past decade or so. But I do think it’s good that people recognize that software may be eating the world, but you can’t eat software. We have to operate in the physical layer.

Do you think Silicon Valley gets more efficient?

Barrett: We need to do the work. You develop the instincts and the platform to deploy capital efficiently into these places.

It’s important that people recognize there’s this unprecedented funnel of technical change. AI is an early indicator of it, but we have technologies like quantum. We know how to produce computation using things beyond transistors and semiconductors.

We’re scratching the surface in terms of AI models. We’re right at the beginning of an explosion and renaissance in materials science driven by things like quantum computing.

Now would be the time — and candidly, I feel the imperative — that anywhere there is science and capital, it needs to be turned into value, especially in liberal democracies, because the despots are doing a pretty good job of it. It’s incumbent on us to stay ahead.

We’re in the DOS age of AI. We’re scratching the surface, both in terms of the models we make and the hardware we run them on.

Now would be the time for people to write checks into things that are sensible and valuable. We spent a lot of time on NFTs. How are we doing with cancer? How are we doing with our most difficult challenges in terms of healing and feeding the world?

There are lots of new degrees of freedom that could take capital and turn it into value.

Do you think deep tech fits the venture thesis, despite the long time horizons and the amount of capital it requires?

Barrett: The long time horizons certainly exist. If you’re building PsiQuantum, we’re building million-qubit quantum machines. That takes billions of dollars and a decadal effort.

The corollary is that we’ve had hardware exits in two years. The timelines for hardware aren’t necessarily that different from software.

Therapeutics naturally take a longer time, because of clinical trials. But we’ve also seen exits there. One of our companies tested half a million drugs in a single animal and created a new corpus of AI input for building models to create therapeutics. That’s not a decadal effort — that’s a handful of years before exit.

We try to craft a portfolio that’s a mix of tactical and strategic. Some of these companies get to hundreds of millions in revenue within a few years. Others, like PsiQuantum or , may take a decade to reach full entitlement. That’s part of portfolio construction.

The biology company you mentioned —��what’s its name?

Barrett: . It did the largest pharma deal of its kind last year with . The deal could be worth $2 billion on the back end.

It’s a unique mechanism to create giant AI training sets by using physical systems — using animals and in vivo testing to create that dataset. It affords the ChatGPT and biology moment, where you can have large enough training sets to build big models.

You describe the firm as investing somewhere between improbable and impossible. Are there companies that really fit that thesis when you first met them?

Barrett: When we first met PsiQuantum, they were talking about building a machine which was 10,000x the state of the art. Using then-current technologies, it would have been the size of the Sierra Nevadas.

They required exponential improvements in both hardware and software, and they’ve achieved both. It’s the size of a warehouse, not a laptop.

The work we’re doing in biology, materials, quantum algorithms and superconducting logic — which will replace transistors and semiconductors — all of these things sound like science fiction, but they’re much closer to improbable. In many cases they’re entirely practical before we invest; they just seem improbable to those unfamiliar with the domain.

There are things that are not impossible but are still really dumb — data centers in space, small modular reactors (SMRs), or fusion. The physics may work, but the economics don’t, or the timelines don’t align.

I’m disappointed we haven’t invested in anything that turned out to be more impossible than we thought. None of our portfolio companies failed because the technology didn’t work.

We’ve had capitalization failures. We flew hydrogen planes. We’ve built things that were thought to be virtually impossible that turned out to be straightforward. They may have missed their market or may have been unable to raise the capital to continue.

I want to do something where the technology doesn’t work, and we’ve yet to do one of those.

Is there a company you missed out on where it looked impossible and you wish you’d invested?

Barrett: I wish I hadn’t taken ‘s word for it when was a non-profit.

We haven’t missed many. As the roadmap developed, we wish we had been earlier in a couple of categories that are really interesting. But overall, we haven’t missed too many.

In which sectors or companies have you invested where the time horizons have shortened due to AI?

Barrett: Adding Pat Gelsinger to the team reflects an interest in scaling semiconductors along various dimensions, including energy efficiency and how power is delivered.

We do everything from nuclear reactors all the way through to transmission, energy conversion outside the data center, inside the data center, under the chip, what kinds of chips you’re running, what models run on top of those chips, what architectures those chips are made from, and what materials those chips are made from.

At every layer of the infrastructure — optical interconnects, memory systems — we have a best-in-class company at every point. We built the first AI accelerator a decade ago, and we’ve broadened that to encompass the entire ecosystem, from the creation of electrons to how they expend themselves doing useful software work.

There are bubbly aspects of the current AI moment, but the bubble is being modulated to some degree by the unavailability of energy.

We’re in the DOS age of AI. LLMs are embarrassingly incompetent compared to what comes next, but we believe in the durability and growth of AI, and are making investments in model architectures and the ways AIs are trained. We see demand for compute, energy and infrastructure continuing to grow.

We have technologies that can reduce general-purpose compute workloads by 100x to 1,000x over state of the art. We believe we know how to make the energy and deliver it. We know how to connect these systems.

So quixotic pursuits like putting data centers in space are unnecessary.

Talking privately to hyperscalers and Fortune 50 companies, they all say there is way more demand for AI in its future incarnation than exists today. It’s incumbent on us to figure out how to do it 100x, 1,000x or 10,000x more efficiently, because that demand turns into GDP growth and better solutions to our hardest problems.

What are the companies in energy and semiconductors that you are betting on?

Barrett: One example is the wild superconducting logic company . We can make things that are post-semiconductor and post-transistor, with devices that switch five orders of magnitude more efficiently than transistors.

They operate at cryogenic temperatures, but quantum computers do that, and our extreme ultraviolet lithography system does that. The future of computation is cryogenic. Even after you pay to make it cold, you’re still 100x to 1,000x more energy-efficient on compute.

This technology has been around since last century, but it’s mainly been used for secure signals intelligence and radar applications. We’re generalizing it for compute.

Another example is . People talk about SMRs, which are a physics solution to a financial problem, or fusion, which is still decades away. Alva instead uprates the existing nuclear fleet to get hundreds of megawatts out of each unit by replacing 1970s steam generators with a 2020 steam generator.

We can deliver power in a handful of years. No new fuel, no new regulatory path, and a business model that makes sense for operators. We can put gigawatts onto the grid without moving a fence line of an existing reactor and without upgrades to the electricity grid.

We know how to make AI training wildly more efficient. We know how to train different kinds of AI models that we’ve been unable to train.

The last supercomputer at uses something unlike a CPU or GPU to run existing software. We’ve been running software the same way for 70 years, but there are other ways, with dataflow architectures. We have a company doing that — [].

The degrees of freedom from materials, systems, code and models have never been greater. We’re exploring all of them. But most require rolling your sleeves up in the physical world.

LLMs feel like brute-forcing something — like a drunk looking for keys under the streetlight. We’re pushing more and more into that, and I think that’s a dead end. We know other ways of moving forward.

Are you seeing new model companies, separate from LLMs, that are going to solve things?

Barrett: Our brains are not LLMs. They’re not transformers. Transformers are effective, but they are one of a long line of soon-to-be-extinct models that get replaced by something that works better.

That millionfold gap between our brains and GPUs is an architectural gap. Meat is much worse at computation than hardware can be, so biology shouldn’t be better.

Physics allows a million times a million more efficiency, and we should start chipping away at that.

Intelligence is useful and can be pressed into service against basic things like photosynthesis. Plants were invented by accident of evolution 3 billion years ago. They’re pretty, but not efficient. They shouldn’t be green; they should be black. We know how to make photosynthesis twice as efficient, and probably 5x more efficient.

We’re not stuck with the physical constraints of our technology or of nature. Nature is beautiful, but cobbled together by a process that we can have agency over.

All the materials that operate our civilization are discovered, not designed, because we can’t design things we can’t simulate. Our best computers cannot simulate the quantum nature of nature. That’s about to change.

We’re stumbling around in the dark, relying on serendipity and the occasional magical material. Whereas we can construct any number of materials with magical properties that are currently hidden from us by our inability to simulate the quantum mechanical processes that animate chemistry.

We are right on that threshold of unlocking all of these dimensions. And at the same time, we’re putting money into NFTs, the metaverse and other things that will come and go, without anybody ever caring.

Are you talking about the mix of quantum with biology and model-focused companies?

Barrett: Quantum allows us to directly design materials, directly explore the method of action of drugs, and directly design drugs.

AI has a role to play in biology and understanding structures we can measure. We think there are quantum wet labs where we can measure the performance of small-molecule drugs against models of nature and then verify in nature.

We don’t know how many things that animate our industry actually work. We don’t know how Tylenol works. We don’t know how the Type II superconductors we’re building fusion reactors out of work. We know that if you take iron and nitrogen and arrange them in a certain way, they produce magnets stronger than rare earth magnets, but we don’t know why.

There are mysterious things we’ve stumbled across that hint at an Aladdin’s cave locked behind a wall of computation. That wall is coming down.

Which sectors do you think are going to take a lot longer to come to fruition?

Barrett: Civilization will operate on fusion eventually, but right now the only reactor that works using gravimetric confinement is the sun. I think that’s a long way off.

Data centers in space are stupid. You can’t operate a gigawatt data center in a thermos. We have terrestrial answers to those questions that we should pursue.

I’ve always been a detractor of self-driving cars, which are starting to work. Now we need an economic model that makes them sensible and doesn’t drown our cities. The problem with transportation in cities is not the degree of autonomy. If we cared about traffic deaths, we’d worry about roundabouts.

There’s also nonsense with NFTs and the metaverse which have sopped up enormous amounts of capital. Small amounts of capital using these tools against our most difficult diseases would yield results. Small modular reactors are an unwarranted innovation.

There are lots of things that, at first blush, seem good and valuable, but there are far better solutions that are simpler and more imminent. We need to be practical about where the money goes.

There was a company that just joined the ������Ƶ, valued over $1 billion this past month, doing orbital data centers. Are you saying this whole category doesn’t make sense?

Barrett: To his credit, will show you a picture of what a 100-kilowatt data center looks like, and it’s bigger than Starship. A 100-kilowatt is a small rack from that is human-sized.

The arguments are that there are a lot of renewables in space. But there are a lot of renewables on the ground too. North Western Australia has solar and wind that are 70% naturally firm, and on the ground, so you can build things on it.

Put a data center in North Western Australia, which we are doing. We have a renewable site 35x the size of Manhattan.

Energy generation and compute in space is a nonstarter because space is not cold. You’re building things in a thermos and need to get rid of heat. A single human-sized rack is 100 kilowatts, which is about the size of the International Space Station’s radiators and solar panels.

Starship has yet to actually put anything in orbit. It’s made some fireworks, which are pretty, and it’s a beautiful thing. is an amazing company because of Falcon 9 and Starlink. But data centers and power generation in space makes no sense.

We know how to build arbitrary amounts of energy generation on the ground with very safe, very large nuclear reactors. We’ve been doing it for decades.

For all the talent and genius rattling around the Valley, we do spend money on silly things.

Do you think now is the most exciting time to be investing, or have some of those investments already been made and are going to come to fruition?

Barrett: We’ve already made investments in things on a really steep trajectory.

Snowcap will take a decade before we’re building GPUs with that technology, but we’ll have commercial product from them next year. We’re getting better at early, undeniable signals.

PsiQuantum is a long journey, but some things just take that amount of time.

X-Lite seems like a ridiculously long journey, although we’re building the prototype facility now, and it received the first money from the new CHIPS Act.

Some hardware companies making silicon or systems are getting significant revenue in a handful of years.

There’s a sleeper in Fund I. Its first trick was to make MRI machines 100,000x more sensitive, and they’re shipping those. In the background they’ve also been developing that core physics to build a new quantum computing modality. So we actually have two quantum computing companies in Fund I.

Even though that’s a 10-year-old company, there are about to be two companies, one of which will be a unicorn virtually overnight.

There are wild things bubbling under the surface that people are going to wonder where they came from.

Companies like — the only co-packaged optics on TSMC — we’ve been working on that for a long time. Now people are waking up to silicon photonics and co-packaged optics.

There are also stealth companies that are indistinguishable from magic. Some of those will come out of stealth this summer.

Is there anything we haven’t chatted about that you think is worth noting?

Barrett: It’s a sobering note, but globally there is a need and desire for sovereign capability in tech — in Western Europe, Australia, Canada and elsewhere.

There are extraordinary pools of capital, pension funds and Australia’s superannuation fund. Given the things we can invest in, globally the West needs to do a better job translating that capital into societal and economic value.

The safety and durability of liberal democracies depends on creating wealth and staying ahead.

We see a resurgent desire to do that in Europe and Australia. Around those pools of capital, there’s ambition. We need to drive that ecosystem globally, not just in the U.S.

The pace of innovation in Ukraine, driven by need, is indicative of changes that can be made in parts of the world less friendly to the tenets we hold dear in liberal democracies.

We can’t operate under the assumption that everybody clever lives in Palo Alto or that we can only invest in things we can drive to. We need to deploy capital globally, and we do. We’re going to do more of that.

Do you feel encouraged by the amount of infrastructure build-out that’s going to happen over the next few years? It feels like it will create a boom in all sorts of technologies because the drive for efficiency will become much stronger.

Barrett: LLMs are not the end. We’ll run LLMs on these data centers initially, but we’ll run their descendants and other more useful things on these machines and on quantum machines.

It’s going to be hard to overbuild because computation is incredibly useful. There’s no upper bound. We’re not in a Malthusian zero-sum game for resources.

We know how to make everything more productive. We know how to grow GDP arbitrarily large. But we need food, energy and medicine there, and we need to normalize the distribution of wealth.

There is unbounded abundance we can unlock if we spend capital on the right things. We know how to do much more of that than people suspect.

The fact that sensible people are considering data centers in space indicates they’re not paying attention to the things we already have in hand that can move the needle.

We do need compute in space. We need AIs in space, sensing in space, and Starlink is great. But we need to use technologies that make sense, not try to make skyscrapers out of toothpicks.

The unicorn board does not reflect internal company valuations — such as those set via a 409a process for employee stock options — as these differ from, and are more likely to be lower than, a priced funding round.

A grab bag of funded startups caught our attention this past month, from a previously bootstrapped custom metal manufacturer that got its first outside funding from big-name Silicon Valley backers, to a startup that aims to provide geothermal energy from underwater volcanoes to small island nations. Let’s take a look.

$110M for on-demand custom manufacturing

First, let’s start with a refreshingly non-AI round, and a sizable one at that.

Reno, Nevada-based said last month that it has raised $110 million in funding led by brothers and founders and , along with and , at a $1 billion valuation.

The company operates an on-demand manufacturing platform specializing in custom-cut metal and fabrication. The round is its first venture investment, and apparently came only after Sequoia’s flew to Reno to woo SendCutSend CEO into accepting Silicon Valley backing. Previously, Belosic had bootstrapped the company, founded in 2018, with personal savings, bank loans and credit cards, he told .

He held little interest in taking cash from startup investors until SendCutSend started to be flooded earlier this year with orders from AI-driven industries including robotics and data centers, and Belosic said he realized the business needed outside investment to grow.

Investor of Paradigm told WSJ that underlying SendCutSend’s booming business is intense demand for rapid, on-demand sheet metal and custom parts. “If you think about the entire frontier of robots, defense companies, rocket companies, electric-car companies, they all need very fast turn prototyping,” he said.

The investment is Paradigm’s first into the manufacturing sector, he noted.

$100M for insurance-covered metabolic health counseling

GLP-1 weight-loss drugs may be booming, but a well-funded startup is betting that medication alone isn’t enough to solve the chronic disease crisis.

, a New York-based metabolic health startup that combines dietitians, AI tools and GLP-1 medication management, last month said that it raised a $100 million Series C round led by . , , and a long list of other investors also backed the round, which brings the company’s total funding to date to just over $213 million, .

Founded in 2021, Nourish operates what it describes as the country’s largest dietitian-led metabolic health clinic, pairing more than 10,000 registered dietitians with AI coaching, lab testing and virtual care. The company has increasingly expanded into GLP-1 prescribing and medication management as demand for drugs such as Ozempic and Wegovy continues to surge.

Nourish said it has partnered with hundreds of health insurers in the U.S. and that its service is covered by most plans.

Its pitch is that the next phase of the GLP-1 boom will require more than prescriptions. While the drugs have transformed obesity treatment, many patients struggle to stay on them long term or maintain results after stopping, according to the company. Nourish is positioning itself as a broader metabolic health platform focused on nutrition, behavior change and ongoing clinical support alongside medication.

“Chronic disease is the central failure of U.S. healthcare — nearly 200 million Americans affected, trillions spent, and outcomes that still don’t move,” Menlo Ventures partner said in a statement. “What Nourish has built in four years is remarkable: a care model that actually bends the cost curve, with 10,000 dietitians, deep payer relationships, and clinical outcomes patients stick with.”

$58M for Gen Z group travel adventures

Group travel startups are having a moment as younger travelers increasingly look for ways to meet people while exploring new destinations.

, a Milan-based startup that organizes group travel experiences for millennials and Gen Z travelers, raised a €50 million (roughly $58 million) Series C funding round as it looks to expand further across Europe and enter the U.S. market. The round was led by .

Founded in 2017, WeRoad operates a platform that connects solo travelers and small groups through curated multiday trips led by coordinators. The company says it has served more than 300,000 travelers across over 1,000 itineraries, with offerings ranging from adventure travel and cultural experiences to outdoor excursions. Participants are typically grouped with strangers in similar age ranges, turning the trips into a hybrid of travel booking and social networking.

“We live in a time when artificial intelligence and social media are reshaping the way we connect with each other. And amid all this digital connection, real human connection has become increasingly rare. Around 30% of young adults say they feel lonely every day. In the United States, this phenomenon is especially significant,” the company said in a statement. “We believe we have an answer. Not the only one, not a perfect one, but a real one: putting people in a room together (or on a quad bike in Morocco, in a canoe in Vietnam, or in front of a sunset in Patagonia) and letting whatever is meant to happen, happen.”

$26M to keep AI data centers cooler

AI may be driving the data center boom, but keeping those facilities cool is becoming a business opportunity in its own right.

, a U.K.-based startup developing precision liquid cooling systems for AI infrastructure, said last month that it raised a $26 million Series B as demand surges for technologies that can manage the growing heat and power requirements of next-generation AI data centers. The round was led by and and brings Iceotope’s total funding to date to just under $100 million, .

Founded in 2005, Iceotope has developed a chassis-based liquid cooling approach designed to replace traditional air cooling and cool entire systems rather than individual chips. The company says it now holds 219 granted and pending patents. It said it will use the new funding to expand product and engineering development, grow its patent portfolio and accelerate partnerships that bring its cooling technology to market.

The raise comes as AI workloads create mounting challenges for conventional cooling systems. Iceotope argues its technology can reduce energy consumption and water use while supporting high-density AI and high-performance computing deployments in both data centers and edge environments.

$25M for geothermal energy from subsea volcanoes

As AI companies scramble for more electricity, investors are increasingly willing to fund some unconventional ideas for generating it. One of those is , a Seattle-based startup developing subsea geothermal power systems designed to tap into heat generated by subsea volcanic activity.

The company recently raised between $25 million and $30 million in a seed round led by , sources familiar with the matter .

Founded just last year, Endurance Energy is targeting island nations — where it says electricity can cost almost 7x as much as in the U.S. — industrial sites and eventually hyperscale data centers that need large amounts of reliable power.

Unlike solar and wind, geothermal energy carries the promise of round-the-clock, renewable baseload electricity, a feature that has become increasingly attractive as AI infrastructure drives soaring power demand.

Endurance says its seafloor geothermal generators could deliver gigawatts of power from hydrothermal systems along tectonic plate boundaries and volcanic regions. It is , where about 80% of electricity generation still relies on imported diesel fuel.

Earlier this year, the company signed an agreement with the Tongan government and launched a pilot project aimed at harnessing geothermal heat generated by subsea volcanic activity around the island nation.

“Clean geothermal power will enable us to substitute most of our diesel base load power and further insulate ourselves from future external shocks caused by geopolitical conflicts and global economic impacts,” Tongan Prime Minister Lord Fakafānua said in a statement.
