Atomic Machines raises $250M for AI hardware factory

Atomic Machines, a California-based startup led by former Uber self-driving chief Jeff Holden, has emerged from stealth with $250 million in funding. The company is developing an AI-guided factory called Matter Compiler that generates tiny mechanical devices directly from digital code, bypassing traditional manufacturing tooling. Its initial product, PrimeSwitch, is a fingertip-sized power switch designed for AI server farms, claimed to be faster and more efficient than silicon breakers. This approach aims to democratize hardware creation by allowing users to design functional micro-mechanisms through software inputs.
