Atomic Machines raised $250 million for no-mold micro-machines, six times Atomic Industries' $42 million
Jeff Holden's Atomic Machines left stealth on October 7 with $250 million to build micro-machines straight from code, no tooling required. That is roughly six times what Atomic Industries, the Warren, Michigan molder built on the opposite thesis, has disclosed.

The tooling-free camp just got its nine-figure check
On October 7, Atomic Machines ended six years in stealth with $250 million raised from OneIM, Gigafund, XTX Ventures and Valor Equity Partners, among others 1. Founder Jeff Holden, Amazon's+2.94% — Amazon, up 2.94 percent today tenth engineer and later Uber's+1.31% — Uber, up 1.31 percent today first chief product officer, claims the firm's Matter Compiler builds working micro-machines directly from code, "with no hard tooling of any kind" 1. Gigafund's Luke Nosek went further: "this is the start of vibe manufacturing" 1. Independent coverage the next morning repeated the core claims 2.
The money is the loudest part
The first product is real and narrow. PrimeSwitch PS-150, a power relay that opens in 50 microseconds, about 1,000 times faster than a conventional contactor, targets the 800-volt DC systems of AI data centers; it ships to early-access customers and gets its first public showing at the Open Compute Project Global Summit in San Jose, October 12–15 1.
Atomic Industries' disclosed total across both its rounds is $42 million: a $17 million seed in late 2023 3 and a $25 million Series A in September 2025 led by MaC Venture Capital and DTX Ventures 4. Against $250 million, private capital has voted roughly six to one for the tooling-free thesis 134.
The tooling-free thesis has drawn six times the money Atomic Industries has raised

Detroit's answer: the press is the moat
Atomic Industries, in Warren, Michigan, argues the opposite end of the same category. It owns its tooling outright, running 1000, 1400 and 2000-ton presses with Velo3D-printed molds for automotive body panels and defense parts, and claims 40–60% faster lead times and $0 tooling cost to customers against a $50K-plus norm 5. Washington has noticed: US Trade Representative Jamieson Greer toured the plant on April 9, 2026, hosted by owners Aaron Slodov and Lou Young Jr. 6
Not yet a customer fight
The two firms sell to different buyers today, micro-machines for data centers on one side, automotive-tonnage plastics on the other 15. The live contest is capital and the "AI-native manufacturing" label. The $250 million is not attacking Atomic's customers; it is attacking its premise. Watch San Jose next week for the hardware, and Atomic's next round for the price of the moat.
