After six years in stealth, Atomic Machines is out. Our mission: on-demand, universal command of matter. First beachhead: the Matter Compiler, an AI-native manufacturing system that builds working micro-machines from code alone. No per-product tooling. No process development. Different code, different machine.

"Doesn't a 3D printer do that?" No. No manufacturing technology to date produces a different machine from a different digital input. Imagine a car factory where, after a couple of cars roll off the line, a laptop emerges. Then a bicycle. Then a refrigerator. A 3D printer gives you a different shape. Not a different machine.

"AI-native" is overused, so here's what it means for us: the entire physical system lives inside the AI loop. Every manufacturing operation is followed by precision metrology. We digitize the physical result, and a part only proceeds if it's in spec. Deterministic process control, not statistical.

That closes the intent→result loop. The AI adapts to errors and runs its own hardware-in-the-loop experiments, generating training data continuously. Our gen AI uses it to produce the device design and the Matter Compiler input to build it. At maturity: prompt-to-product manufacturing.

We've aimed the Matter Compiler at micro-machines: tiny machines with moving parts, features measured in microns. Think millimeter-scale robots. The universe is a grid: 7 physical domains × 2 purposes (deliver energy and matter, or encode information). Semi fab has mastered one cell. Six are empty.

MEMS engineers have brilliantly coaxed a few devices out of the semi toolset over decades: accelerometers, gyros, micro-mirrors, inkjet nozzles. But the rest of the grid needs processes and materials semi fab was never built for. That's what the Matter Compiler brings.

First micro-machine out: PrimeSwitch PS-150, a new class of power relay. 200 µΩ on-resistance → 150 A continuous in a 9.5 mm × 3 mm hermetic package. Opens in 50 µs to 1,500 V of true galvanic isolation, ~1,000x faster than a contactor. Zero holding power. Shipping to early-access customers now.

Why it matters: AI data centers are moving to 800 VDC, where a fault delivers destructive energy in microseconds and a DC arc won't put itself out. Mechanical protection is milliseconds too slow. Solid-state is fast but can't isolate and bleeds heat on every amp it carries. PrimeSwitch is the device in between that nobody could build.

In a hybrid breaker with a solid-state bypass: the silicon interrupts, the metal carries and isolates, the breaker never arcs. The same device does transfer switching, hot-swapping, and generally economizes semiconductor power across the 800 VDC data center.

No semiconductor fab can process PrimeSwitch's materials or assemble its moving parts. It exists because the Matter Compiler exists. Matter Compiler named for @nealstephenson's The Diamond Age. $250M raised to date. See it at @OpenComputePrj Summit, San Jose, Oct 12–15. So proud of our insanely multidisciplinary team!
