Funding, Fusion, and Fine Print: Inside AI's Wild Summer

LaurenYou

DerekHey, everyone. Welcome back to Tech Insider Weekly. I'm Lauren.

Speaker 3And I'm Derek. So Lauren, today's episode is basically a money and nuclear reactor sandwich.

DerekThat's one way to put it. We've got a startup funding round that broke every record we track.

Speaker 3Right. And one ship company just jumped to an 11-figure valuation in a single round.

DerekWe'll dig into what's actually driving all that cash.

Speaker 3Then, switching gears here, nuclear power is having a moment nobody... Nobody predicted.

DerekA thorium reactor you can basically print like a document?

Speaker 3Something like that. Plus a satellite, a fusion bet from Google, and NVIDIA getting into the water-saving business.

DerekNVIDIA, water, and nuclear reactors. Never thought I'd say that sentence.

Speaker 3Oh, you're going to love this part. NVIDIA is also handing startups a new compute deal.

DerekIs it a gift or a leash? We're going to argue about that one.

Speaker 3Well, I already have a take.

DerekOf course you do. And we're closing on something more personal. Who's actually getting hired at these AI startups right now?

Speaker 3Spoiler, maybe not who you'd expect.

DerekAlright, Derek, let's start with the money.

Speaker 3Let's do it.

DerekOkay, so get this, $5.10 billion, that's what flowed into startups worldwide in the first half of 2026.

Speaker 3That's $5.10 billion with a B.

DerekJoanna Teare at Crunchbase News called it a record, and AI is basically the entire reason.

Speaker 3It's not just global either. Joanna Glasner reported on Crunchbase that North America alone hit $392 billion. billion for the same six months.

DerekOkay, but what actually happened here? I sat through two hype cycles at startups I worked for, and both times everyone swore it was different.

Speaker 3And both times?

DerekIt wasn't. So what's actually different now?

Speaker 3Compute. Real physical demand. Look at SambaNova. Reuters reported they just raised a billion dollars at an 11 billion dollar valuation.

Derek11 billion for a chip company?

Speaker 3An AI chip company. Wait, back up. This isn't an app with a nice interface. This is silicon. Somebody has to build the thing that actually runs the models.

DerekWhich is a very different bet than 2021 when everyone was funding a grocery app with a raccoon logo.

Speaker 3I remember that raccoon.

DerekWe all remember the raccoon, Derek.

Speaker 3Fair enough.

DerekSo the money's chasing actual infrastructure. Fine. But my skeptic hat says an eleven billion dollar tag on unproven margins still smells a little bubbly.

Speaker 3Maybe, but look at unicorn production: Blockster counted nearly ninety new unicorns minted just in the first half of this year, most tied straight to AI infrastructure.

DerekNinety in six months?

Speaker 3Ninety! Chips, data centers, robotics, enterprise software-that's the mix Blockster flagged.

DerekThat's a nice story, but show me the numbers behind the numbers. Is that revenue growth or investors terrified of missing the next NVIDIA?

Speaker 3Honestly, probably both. Nobody's got a clean answer.

DerekRight, right, right. Because every time I've seen this pattern up close, it's fear driving the valuation, not the fundamentals.

Speaker 3Maybe, but the fundamentals argument this round is you can't train these models without more chips and more power. That part's real, whether the valuations hold or not.

DerekAnd power is doing a lot of work in that sentence because all this cash has to land somewhere physical, which

Speaker 3Yeah,

Derek:

Speaker 3it's got to plug into something.

Derekis where this gets a little wild because these data centers are hungry in a way regular servers never were.

Speaker 3Hungry enough that people are talking about nuclear reactors again.

DerekWait, seriously? Actual reactors powering AI?

Speaker 3So how exactly do you keep a data center running when the grid can't keep up?

DerekOK, building on that grid problem, turns out somebody already printed a solution.

Speaker 3Oh, this one's wild. Jowi Morales at Toms Hardware reported a startup 3D-printed an actual nuclear reactor module. Subcritical solid state thorium fueled.

DerekWait, back up. That's supposed to be my line. OK, subcritical for those of us who skipped nuclear physics.

Speaker 3So it means it can't run away into a meltdown. The reaction needs an outside driver to keep going, factory-built module by module. Dan Robinson at the Register says it's rated for up to 30 megawatts, up to 30 years.

DerekThirty years without refueling? That's a reactor you install once and forget.

Speaker 3Which is the pitch for data centers. Nobody wants a fuel swap crew next to their server racks.

DerekOkay, but why now? Why is everyone racing toward tiny reactors instead of, I don't know, more solar?

Speaker 3Solar doesn't run at 2 a.m., and AI training doesn't stop at sundown. Constant load needs constant power.

DerekFair? Switching gears, this next one made me actually gasp reading it.

Speaker 3I know exactly which one.

DerekSpaceX launched the first ever nuclear-powered commercial satellite. Josh Dinner covered it for Space Yesterday.

Speaker 3A satellite

DerekWow.

Speaker 3that doesn't need sunlight to keep running.

DerekNo solar panels at all. How does that even work up there?

Speaker 3Radioisotope power, most likely. Heat from decay converted straight into electricity. NASA's flown that on deep space probes for decades, but a commercial satellite is a different bet entirely. Clearly.

DerekAh, so in one week we've gone from reactor in a shipping container to reactor in orbit.

Speaker 3Same week. And then there's Proxima Fusion.

DerekYes, Bloomberg reported Google and RWE just backed this German fusion startup at a 2.4 billion euro valuation.

Speaker 3Google betting real money on fusion, which, let's be honest, has been 20 years away for something like 60 years.

DerekThat's serious money for something science fiction writers used to dream up.

Speaker 3Or physicists having a very expensive argument for sixty decades.

DerekThat joke never gets old, huh?

Speaker 3Never does. But Google's not funding this out of curiosity. They need power for their own data centers. And fusion never runs out of fuel and never melts down.

DerekSo it's not charity, it's supply chain management.

Speaker 3Basically. And speaking of resources beyond power, Reuters reports

Speaker 4that Google is working on a new battery technology that could give electric cars more than twice the distance of the new Tesla.

Speaker 3Traders reported nuclear startup Valar partnered with Nvidia on a data center built specifically to save water.

LaurenWater? I thought this whole thing was about electricity.

DerekIt's both. Data center cooling drinks millions of gallons. Pair that with a plant that recycles its own cooling loop, and you solve two resource problems with one build.

LaurenOkay, so reactors handle the power side, but you still need chips to actually do anything with it.

DerekWhich is the other half of the equation, and Nvidia just made a pretty interesting move on exactly that front.

Speaker 3music

LaurenOkay, flip that on its head for a second, because reactors in fusion solve the power problem.

DerekRight, but chips are the other half of the math.

LaurenExactly, and Nvidia just made a move I need you to translate for me.

DerekSo Storyboard18 reported this. NVIDIA's rolling out a revenue-sharing model for AI startups and cloud providers.

LaurenIn English, please?

DerekOkay, for the non-engineers in the audience, instead of paying full price up front for GPUs, A startup gets access to NVIDIA's compute, in an exchange NVIDIA takes a cut of whatever revenue that startup makes down the road.

LaurenSo it's less buy the hardware and more rent now, split the winnings later.

DerekBasically. And their CFO, Colette Kress, framed it as giving startups faster access to infrastructure they couldn't otherwise afford.

LaurenFaster access or NVIDIA just found a way to get paid twice.

DerekWell...

LaurenNo, seriously, what does NVIDIA actually get out of this? this.

DerekBloomberg's take was pretty direct. They called it a play aimed at quote aspiring AI startups, basically the companies that can't write a nine-figure check for chips today.

LaurenWhich sounds generous until you realize Nvidia's now got equity-like exposure to every company it powers.

DerekYeah, BeInCrypto actually used the phrase deepening its ecosystem grip. That's their read, not mine.

LaurenDeepening its grip. I mean, sure, call it a lifeline. I'd also call it a leash. Leash.

DerekWait, back up. It's not that different from how VCs already work, right? Cash for a piece of the upside.

LaurenExcept Nvidia is not just an investor here. They're also the landlord, the supplier and now the equity partner. That's three seats at the table.

DerekWhen you put it that way.

LaurenRight? And remember the funding numbers from earlier. Startups are sitting on more cash than ever.

DerekSure, but a huge chunk of that cash gets eaten by compute costs before it even touches paper. Such as payroll.

LaurenWhich is exactly why this deal is tempting. You're cash rich on paper but GPU-poor in practice.

DerekSo do founders take it or do they see the trap?

LaurenHonestly depends on how desperate they are for compute versus how much control they're willing to give up.

DerekYahoo Finance framed it as Nvidia making it easier to get compute power. Benzinga used almost the same language. Easier access, advanced GPUs, no giant check.

LaurenEasier for who, though? The startup or Nvidia's balance sheet?

DerekLuckily both, probably. That's kind of the point of a good deal.

LaurenI'll believe it's good once we see a founder walk away from one.

DerekFair. Nobody's turned it down yet.

LaurenThe thing that gets me, startups are burning cash on chips instead of people.

DerekYeah, which raises a whole different question: who's actually getting hired at these companies right now?

LaurenOoh, now that's a conversation I want to have.

DerekBecause it turns out the answer might not include very many junior engineers at all.

LaurenGreat, another thing for new grads to panic about. Let's get into it. Pivoting Pivoting a bit, let's talk hiring because the compute obsession has a headcount cost too.

DerekRight. In Harvard Business School and INSEAD just put a number on it. Their study found AI-native startups run about 25% smaller than traditional companies at the same valuation.

LaurenTwenty five per cent smaller; that's a different org chart entirely.

DerekOwais Sultan wrote about this for Hackread: "Startups are building global teams with contractors and EOR partners instead of stacking headcount in one office.

LaurenLean and distributed. Okay, I get the instinct-I ran ops at a startup where we hired eight people for a job three could do, and it nearly sank us.

DerekSo the Lean logic makes sense on paper.

LaurenBut there's a catch. Fortune's Emma Burleigh reported these companies are skipping entry-level hires almost entirely, chasing senior engineers with top-tier degrees.

DerekBusiness Insider covered the same Harvard data: fewer junior hires, flatter teams, more people who already know what they're doing.

LaurenAnd that's exactly the mistake I made early on. Hire only proven people, and you never build anyone yourself.

DerekWhich raises the real question for me as an engineer: If nobody's hiring juniors, who trains the next generation of engineers?

LaurenThe senior people we all fought with didn't start senior.

DerekSomebody gave them a shot on day one.

LaurenSo if every AI startup skips that step, where does the next Derek come from?

DerekDon't put my name on that." Fair,

Lauren"but seriously, five years from now, does the industry have a bench or just a shrinking pool of people who already made it? eat it.

Speaker 3Mm-hmm.

LaurenOkay, so today went from reactor in a shipping container to reactor in orbit, and honestly, my brain is still catching up.

DerekSame. And underneath it all, one thread. Compute needs power, and power needs new thinking.

LaurenRight, and that funding number we opened with isn't just hype. Somebody's actually building the physical stuff behind these models.

DerekWhich loops back to hiring. Leaner teams, fewer entry-level seats. Worth watching where that goes. where that goes.

LaurenDefinitely a thread we'll keep pulling.
