Overview
Atomic Machines is an Emeryville, California deep-tech company developing the Matter Compiler, an all-digital manufacturing platform designed to fabricate multi-material micro-machines with moving parts without fixed tooling. Its first announced product, PrimeSwitch PS-150, targets high-voltage AI data-center power systems.
Why Atomic Machines is interesting
Atomic Machines is attempting to make complex microscale hardware programmable, compressing the custom process-development cycle that defines conventional MEMS manufacturing.
Product & use cases
Matter Compiler combines digital process control, metrology and automated experimentation to manufacture small multi-material devices from code. PrimeSwitch PS-150 is the first disclosed product.
- High-speed power protection for 800-volt DC AI data centers
- Programmable fabrication of microscale machines
- Future medical microrobotics and chip-integrated cooling
Key facts
- Emerged from six years in stealth with $250 million of aggregate funding.
- PrimeSwitch PS-150 is shipping to unnamed early-access customers for evaluation.

Competitive landscape
Edge: A closed-loop manufacturing stack that measures and corrects fabrication steps in real time, paired with a first commercial product aimed at the urgent 800-volt DC transition in AI data centers.
Atomic Machines sits between additive manufacturing, MEMS foundries and semiconductor process equipment. The central question is whether one programmable platform can deliver repeatable yield across multiple device classes.
-
Silex Microsystems incumbent
Established MEMS foundry alternative requiring custom process development.
-
Standard semiconductor and MEMS foundries alternative
Provide mature manufacturing capacity but depend on fixed tooling and lengthy process qualification.
