Flow Engineering raises $50 million for AI hardware engineering platform

Flow Engineering announced a $50 million Series B at a company-stated $750 million valuation. Antonio Gracias of Valor Equity Partners and Gavin Baker of Atreides Management co-led the financing.

Flow plans to put the capital toward what it calls an AI harness for hardware engineering, along with review, branching, evaluation and program-control capabilities. The company also said it will hire in AI and systems engineering, pursue FedRAMP authorization and other certifications, and expand sales.

The platform, in Flow’s description, is a living system of record connecting requirements, computer-aided design, simulation, code and tests. The company said its software agents analyze engineering changes, identify downstream effects, and check requirements and test coverage across physical-product programs.

Flow said Sequoia Capital, Human Capital, Evantic, SV Angel, Odyssey and EQT also participated, alongside individual investors Thomas Wolf, Jonas von Malottki and Nico Rosberg. It also said Sequoia partner Roelof Botha joined its board as an independent director and invested personally in the round. For funding context, DataPhoenix has also covered Celero Communications’ $275 million Series C.

In a letter accompanying the financing announcement, Flow named customers including General Motors PPU, RV Tech, Anduril, Stoke Space, Intuitive Machines, Pacific Fusion, Rivian, Joby Aviation, Astranis and Radiant Industries. That roster is a company claim. Flow also said Rivian adoption rose from 40 to 1,500 users in seven months and that Rivian engineers make millions of API calls each week; the disclosed sources do not independently substantiate those figures.

Flow separately described a three-year partnership with Rivian and Volkswagen Group Technologies under which RV Tech uses the platform to link requirements, system architecture and tests. In Flow’s account, RV Tech executives said the deployment centralizes documentation, traces the effects of engineering changes and integrates existing engineering tools.
