About Atomic Machines

Atomic Machines states its mission as achieving “on-demand universal command of matter”. Its starting point is the micro-scale — the territory between semiconductor features measured in nanometres and cast or machined parts measured in centimetres, where machines are small, intricate, three-dimensional and made of many materials at once, and which the company says remains largely unbuilt for lack of tools rather than physics. To build in that territory it created the Matter Compiler™ (MC), an AI-native manufacturing stack built from the ground up. The company describes the MC as a general-purpose constructor: a single system in which code alone determines the device produced, building complete, functional three-dimensional machines with moving parts, many materials and assembled subsystems, with features down to single-digit microns and no hard tooling of any kind. The entire physical system sits inside the AI’s loop — every operation is measured with high-precision metrology and corrected in real time — which is what the company says will allow one-shot prompt-to-product manufacturing.

The first device out of the Matter Compiler is PrimeSwitch™, an electromechanical power relay aimed first at the 800-volt DC power systems of AI data centres. The company’s reasoning, as published: power density keeps rising, and the two existing switching technologies each hit a wall — semiconductors switch in microseconds but lose energy as heat in continuous conduction and cannot provide galvanic isolation, while mechanical relays and contactors conduct almost losslessly and open a true gap but take milliseconds and open into an arc at high power. The first model, PrimeSwitch PS-150, is a bistable relay that opens in 50 microseconds with on-resistance of 200 µΩ and 1,500 volts of galvanic isolation at a continuous current rating of 150 amps, in a hermetically sealed surface-mount package 9.5 mm across and 3 mm thick, holding its state with zero power. Deployed in a hybrid breaker alongside a small solid-state bypass, it is intended to deliver mechanical conduction efficiency and isolation at solid-state opening speeds. The company states the PS-150 is sampling now and shipping to early-access customers for evaluation, and that PrimeSwitch was shown publicly for the first time at the Open Compute Project Global Summit in San Jose in October 2026.

Atomic Machines, Inc. is a United States company headquartered in Emeryville, California, with a second office in Santa Clara. It emerged from stealth on 7 October 2026, announcing that it has raised US$250 million to date. Third-party company databases list a 2019 founding; the company does not publish a founding year and describes six years in stealth before its public launch, so the founding year is recorded here as reported rather than settled. Its official website is https://www.atomicmachines.com. Its profile status is recorded as not yet claimed, and the facts in this record were last verified on 14 November 2026. This company is not Atomic (atomic.supply), the supply-chain planning software company listed separately in this directory.

Products & services

• Matter Compiler™ (MC) — AI-native, all-digital manufacturing system that builds complete, working micro-machines directly from code: three-dimensional devices with moving parts, multiple materials and assembled subsystems, features down to single-digit microns, no hard tooling, and no new process to engineer per device. Every operation is measured with high-precision metrology and corrected in real time (company-stated). The MC is the platform Atomic Machines uses to produce its own devices.
• PrimeSwitch™ — the first product family produced by the Matter Compiler: a new class of electromechanical power relay combining metal-to-metal conduction efficiency with microsecond opening and true galvanic isolation.
• PrimeSwitch™ PS-150 — bistable SPST electromechanical relay. Published specifications: 150 A continuous current (AC or DC, no active cooling needed); opening time 50 µs to 1,500 V with true galvanic isolation; on-resistance 200 µΩ; holding power zero (bistable); hermetically sealed surface-mount (SMD) package, 9.5 mm diameter × 3 mm. Status: sampling now; shipping to early-access customers for evaluation (company-stated). First market: protection for 800 V DC power distribution in AI data centres, deployed in hybrid breakers alongside a small solid-state bypass.

GlobleMatch Trust Signals

A directory that doesn’t sell stars. Trust Signals are built only from verifiable facts — never from anonymous ratings, and never for sale. There is no single hidden score.

Public information coverage	7 of 9 fields on the standard profile could be filled from public sources. This counts how much public information exists about the company — not how good the company is. The nine fields are listed in the methodology. Claiming the profile lets the company complete the remaining fields itself.
Last verified	14 November 2026 — facts on this profile were checked against the sources listed below. Profiles are re-checked on a published 90-day cycle; this date is never quietly refreshed.

Claim this profile to unlock response record, directory tenure and peer endorsements. The full methodology — what each signal measures and how it is calculated — is published in the Trust Signals methodology, including a change log.
