Atomic Machines exits six years of stealth with $250M for an AI-driven system that builds micro-machines from code
The Bay Area company disclosed on Wednesday that it has raised $250M in total, without naming a lead or saying how the sum splits across rounds. Backers include OneIM, Gigafund, XTX Ventures, KAS Venture Partners, Valor Equity Partners, Sozo Ventures and the Regents of the University of California. Founder and CEO Jeff Holden was Amazon's tenth engineer, built Prime and later served as Uber's first chief product officer. Its Matter Compiler fabricates multi-material micro-machines with moving parts and features of a few microns directly from code, with AI running its own experiments on the hardware and correcting every step. The first device, PrimeSwitch PS-150, is a 150-amp relay for 800-volt DC data center power that the company says opens in 50 microseconds. It is shipping to unnamed early-access customers and will be shown at the OCP Global Summit in San Jose from October 12 to 15. For builders, power delivery is turning into a hardware bottleneck in AI data centers, and capital is reaching component makers, not only chip and model companies.
