Jeff Holden's Atomic Machines Exits Stealth With $250M to Code-Compile Micro-Machines for AI Data Centers

Amazon Prime creator and ex-Uber CPO Jeff Holden emerged from six years of stealth with Atomic Machines, backed by $250M, pitching a 'Matter Compiler' that fabricates 3D micro-machines directly from code at single-micron tolerances. The first product, the PrimeSwitch PS-150 electromechanical relay, opens in roughly 50 microseconds — about 1,000x faster than conventional contactors — and is aimed at 800V DC AI data center power distribution.
