Atomic Machines raises $250M to build tiny machines from code with AI
Atomic Machines, a California startup led by former Uber self-driving chief Jeff Holden, has emerged from six years of stealth with $250 million in funding. The company’s AI-driven factory aims to turn digital designs into functional, tiny machines—such as micro-pumps, motors, and gears—without traditional retooling. Each production step is verified by AI, which also learns from real-world…
Key points
- Atomic Machines raised $250M after six years in stealth, led by ex-Uber self-driving chief Jeff Holden
- AI factory builds microscopic machines like pumps and motors, verified step-by-step by AI
- First product, PrimeSwitch, targets AI server farms with faster, more efficient power switching
The startup’s first product, PrimeSwitch, is a fingertip-sized power switch for AI server farms. Atomic Machines claims it outperforms traditional breakers in speed and efficiency. While currently focused on its own products with human oversight, the long-term vision is to enable ‘prompt-to-product’ manufacturing, allowing virtually anyone with a concept to create physical devices. The company emphasizes that its Matter Compiler can adapt designs dynamically, unlike 3D printers, which only alter shape.
