Good morning, champions. Welcome to Tuesday. 🕶️
Kairos Power just pulled $100M from Samsung to build a 50-megawatt nuclear reactor wired straight to Google. Not a contract to buy power, a plant. The grid couldn't keep up, so they're building their own.
In today's newsletter, we'll get into:
Turning four comments into revenue
Harvey's margins torched in six months

RUSHIN' ROULETTE
Five bullets of updates
💸 Harvey, a $15.6B legal AI startup, is rebuilding its stack on open-weight models after gross margin crashed from +50% to -50% in six months. With Abridge, a clinical note tool, and Decagon, a support platform, also shifting, startups are moving off pricey APIs to cap inference costs, repair margins, and lessen dependence on big-model vendors.
💍 Oura, the Finnish smart-ring maker, is launching a $2.2B IPO that will route 73% of proceeds to existing shareholders instead of the company. The deal underscores how late-stage investors may prioritize cashing out over fueling growth, even as Oura juggles a membership-driven model, rising warranty costs, and health-tracking accuracy concerns.
🎤 London-based entertainment startup Unit1 Studio has raised £20M to build portable concert tours for AI-enhanced musician avatars. The funding backs a model that gives artists higher royalties and lets their digital doubles play posthumous performances or simultaneous shows in multiple cities, decoupling premium live music from physical touring logistics.
🚇 Elon Musk’s tunnel startup The Boring Company is pitching a roughly 80-mile Hyperloop link between Austin and San Antonio. But investors and city officials are weighing it against the company’s history of unbuilt tunnel proposals, turning this into a test of whether regulators and capital markets still fund grand transport ideas without evidence of delivery.
💍 Vocci, a meeting-notes hardware startup, is selling a $249 AI-powered smart ring that records conversations and auto-generates notes. The ring’s always-on, hard-to-notice design makes discreet audio capture trivial, forcing companies to revisit meeting consent norms, surveillance risks, and how off-laptop wearables fit into data-governance policies.
Which recorder crosses from notes into surveillance?

STARTUP NEWS
Samsung backs a nuclear startup so Google can think

Remember when tech giants just bought power?
Yeah, those days are dead. Google isn't shopping for electrons anymore. It's building the plant. Think of it less like a customer and more like a feudal lord digging his own well because the village pipes are a joke.
Here's the deal. Kairos Power, a scrappy nuclear startup, just quietly grabbed up to $100M from Samsung C&T. Not just cash: $70M in equity, the rest in engineering muscle, since Samsung's now running the build. The prize? A 50-megawatt reactor wired straight to Google.
And the pace is nuts. Back in fall 2024, Google pinky-swore to buy roughly half a gigawatt of nuclear juice by 2035. By late 2024, Kairos snagged NRC approval to break ground in Oak Ridge. Now, two reactors are rising: Hermes 1, the demo, and Hermes 2, the real moneymaker, targeting 2030.
So what's the myth here? That the grid was ever going to save you. It won't. AI data centers eat power like nothing before, and utilities are still stuck in decade-long upgrade cycles.
The founder takeaway: if your compute bill is exploding, power is now a product line, not a utility invoice. Model it. Source it. Maybe co-build it.
Kairos has five years to finish plant one, then must go faster. Watch the concrete pour. That's your signal.

The brilliant scam of "Dolby Atmos"
🎬 Dolby Atmos is everywhere.
Your TV has it. Your headphones have it. Netflix says your favorite show has it.
But... is it actually Dolby Atmos?
In this episode, Caya dives into the 70-year history of surround sound—from Cinerama and Dolby Stereo to Dolby Digital, DTS, and Atmos—to uncover what Atmos really is, why it's become the default marketing label, and why most people may never hear the real thing.
We also build a home theater, compare audio formats, install ceiling speakers, and answer the question: is Dolby Atmos actually worth it?

BIG TECH NEWS
Amazon to Meta and Perplexity: no bots on my lawn
Amazon just pulled a Godfather move: it made two AI shopping bots an offer they couldn't refuse, except there was no offer, just a door slammed in their faces.
What actually happened?
In case you missed it, Amazon blocked Muse and Perplexity. It cut off Meta's AI shopping assistant, Muse, citing a breach of its Conditions of Use. Same week, it filed an amended complaint against Perplexity, accusing the company's Comet agent of misleading a federal court about how it pokes at Amazon's servers. Harsh. Effective.
So why does Amazon care this much? Follow the money. Every bot that reroutes shoppers around Amazon's browsing experience also reroutes them around its $68 billion advertising business. That's the whole ballgame. Amazon isn't defending user experience here, it's defending its cash machine.
Who actually gets hurt?
Not Meta. Not Perplexity. The real casualties are the little guys: seed-stage founders building price-comparison tools, browsing extensions, and personal shopping agents on top of scraped marketplace data. Roughly 60% of those data pipelines just became decorative overnight.
The lesson, plainly stated: if your moat is unauthorized access to someone else's platform, you don't have a moat. You have a countdown clock. Build on first-party data and official APIs, or build somewhere the landlord can't evict you this week.
Watch Perplexity's next legal filing. It's the first real signal of how AI builders plan to fight, or fold.
