HQ Los AngelesFounded 202411-50 employees
General Matter is a domestic uranium enrichment startup closing a critical gap in the U.S. nuclear fuel supply chain. With the U.S. nearly absent from global enrichment despite being the world's largest nuclear power consumer, General Matter is developing cost-competitive technology to produce both LEU and HALEU, backed by surging energy demand and reshoring policy tailwinds.
