General Matter is enriching uranium in America.

Our mission is to restore our country’s ability to make nuclear fuel. Our fuel will help power AI, manufacturing, and other critical industries. It will power our next generation of reactors. Ultimately, it will power our national ambitions.

We were incubated by Founders Fund, like Anduril and Palantir before us, and we are backed by top tier investors.

Our lean, world-class team of engineers and operators is applying a first-principles approach to solving the problem of nuclear fuel production.

We are a mission-driven company with a culture of urgency, accountability and transparency.
