Nuclear energy is carbon-free, reliable 24/7, and incredibly safe -- yet it remains misunderstood, rarely celebrated, and deeply underinvested in. I wrote this essay about why that is, and how we can build more of it. Comments/Qs/feedback welcome! https://t.co/NwizW9OP1J

Excited to share that we've raised a Series B!
We just raised $96M to build and deploy our microreactors. This round powers the work ahead — advancing our hardware, maturing our operations, and paving the way for our first reactor demonstration in 2026. Two years in: 60 people, three states, a 145,000-sq-ft facility, and

6 months in Huntsville → our first full-scale prototype built and tested. Full-scale components. Real temperatures. Real pressures. Real data shaping the reactor we’ll take critical in 2026.

No gimmicks, stunts, or marketing props. Just 6 months of vaporizing sodium to test our heat pipes and heat exchanger!

Congrats Cam!! Incredible progress in such a short time, proud to be both a customer AND investor! 🚀
For too long the world of hardware testing has been stuck in the past. Our mission at @Nominal_io since the beginning has been to change this - to give hardware engineers and organizations a new suite of tools to help them build the physical world that moves, powers, and protects

Nuclear podcast drop! A must-listen on all things nuclear and where Antares is headed with my co-founder @jordanbramble and our Series A lead and board member @jaltma 🙌
I sat down with @jordanbramble, CEO of Antares, to talk about nuclear energy in the US. Antares builds small modular nuclear reactors for the military and other applications. His knowledge of the history and present of the market is encyclopedic and I learn a ton whenever I get

Congrats @eriktorenberg! a16z is lucky to have such a beacon of curiosity, relentlessness and humility on its team.
I’m excited to share that: 1. I’m joining Andreessen Horowitz as a general partner. 2. a16z has acquired Turpentine. Everything I’ve worked on over my career has been around investing and building products/networks/media for founders — a16z is the perfect place for me

General Matter is enriching uranium for the US. We will revive nuclear fuel production in America. We chose to do this not because it’s easy, and not because it’s hard, but because it needs doing. Nothing gets made if fuel isn’t made. America’s ambitions, from manufacturing to

First it was reversing course on Diablo Canyon's scheduled closure, now California is considering allowing new nuclear to be built 🥹 Exciting to think California could finally be headed in a positive direction on nuclear energy. But it's not a done deal yet - make your voice
