Foundry Robotics raises $100 million Series A to own and run an autonomous assembly factory

Foundry Robotics has raised a $100 million Series A led by Marlinspike Partners, the company said on Oct. 28. Khosla Ventures and Red Glass Ventures, which backed it early, joined new investors SE Ventures, Wing VC and Axiom Ventures, with existing investors Hanabi and Zero Shot Fund. Foundry did not give a valuation, RuntimeWire reports.

Foundry is not selling robots. It owns and operates the factory and sells the output: customers bring a design and, the company says, get to production in weeks without paying for new production lines or retooling. That makes it a contract manufacturer with robot cells, run by an agentic system it calls FoundryOS, and its business stands or falls on keeping a 130,000-square-foot plant busy. The company, founded in 2026, says that site in Emeryville, California, is a twentyfold expansion of its manufacturing footprint, and the money goes into building it out, deploying its AI models on the floor and hiring.

The first demand it names is military. Products listed in the release include drones, underwater vehicles, wire harnesses, autonomous vehicle subassemblies and satellites. "Production capacity is a national constraint on getting unmanned systems to the fleet," said Duane Fotheringham, president of HII Unmanned Systems, in the release.
