Zenithon AI just raised $10m from Backed, Lunar, Seraphim, MMC, SOSV and others. It's building AI that runs complex physics simulations a million times faster than today's tools, so engineers can test…
Um, now world models for vision are beginning to have an impact on, um, certain sectors as well.
But really, we haven't seen this for physics, and so this is exactly what we're building to try and unlock some of the most important technologies of the 21st century.
I've always been, you know, really drawn to how can we make a positive impact, but also obviously just sci-fi, like, like any physicist, I guess.
And I worked for three years in trying to commercialize this, working with about 20 different fusion companies on, you know, how can we both accelerate the development of this, but do it in a way that is relevant and will have an impact on the economy.
And I realized that, you know, the core iteration loop, you know, this build, measure, learn iteration loop, which is essential for any startup, was just so slow and so painful.
Um, and so that drove me to do a PhD in AI for plasma physics to see if I could speed it up.
But, you know, um, I got halfway through, and I was just very frustrated about...
You know, I was just kind of working away in my, in my basement, uh, at, in Cambridge and not really having an impact in the world.
And so was able to raise our pre-seed, uh, dropped out and, and hired my favorite, um, researchers and, and was very fortunate to, to have Abhi, my co-founder, join as well.
