About the Company

General Matter enriches uranium.

We are designing, building, and operating the world’s lowest-cost enrichment services, here in the US.  

In the process, we are restoring America’s ability to produce nuclear fuel to power AI, advanced manufacturing and critical industries our country relies on to remain competitive. 

Fuel drives the cost of advanced reactor electricity production, and enrichment drives the cost of the fuel that advanced reactors consume.  Reliable, low-cost enrichment is the catalyst for the nuclear Renaissance now under way.

Our mission is to make nuclear not only the cleanest and safest source of baseload power, but also the most affordable.  We believe abundant nuclear energy will lead to a post-scarcity society. 

We were incubated inside Founders Fund, like Anduril and Palantir before us, and are backed by over a dozen of the world's top venture capital firms.  

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. 

Help us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable.

About General Matter

General Matter is enriching uranium in America.

Our mission is to restore US leadership in nuclear fuel. This fuel will power AI, manufacturing, and other critical industries. It will enable the next generation of reactors and the reactors powering ~20% of the US grid today. Ultimately, it will power our national ambitions.

If we don’t do it, no one will.  Half a century ago, the US held a majority of all global enrichment capacity. Today we are forced to rely on foreign powers and their state-backed, state-controlled entities for the nuclear fuel that powers nearly 20% of our nation’s grid.

We are fixing this. By uniting the nation’s finest minds from technology, nuclear engineering, national security, and finance, we are building a new way to enrich uranium, here at home. The fuel we are enriching will be cheaper, more reliable, and more abundant than ever before, and it will result in a stronger America.

As we build our team we are seeking the highest caliber engineers, technologists, creative minds, and numbers savants. We offer high standards, extreme ownership, copious autonomy, deep trust, and zero politics. We believe that despite our ambitious mission, our chances of success are great. If you are someone who will further tilt those odds in our favor, we want to talk to you.
