Flow Engineering wants hardware teams to move at the pace software teams have enjoyed for years, and investors have handed it $50M to try.
The Series B values Flow at $750M. Antonio Gracias, the founder of Valor Equity Partners, co-led the round. Atreides Management’s managing partner, Gavin Baker, was the other co-lead. Sequoia Capital, which had backed the earlier Series A, returned to the table. Human Capital, Evantic, SV Angel, Odyssey and EQT also participated.
What Flow sells is a set of AI agents that live inside the tools engineers already open: CAD, Git, simulation software and documentation. They chart impact, surface conflicts and catch failing requirements, cutting validation and verification work from months to days.
The pitch rests on where errors get caught. Physical products are punishingly expensive to fix once tooling exists, so Flow argues the savings come from resolving clashes in the design phase rather than on a factory line. GM Performance Power Units, Rivian, Volkswagen’s RV Tech joint venture, Anduril, Stoke Space, Intuitive Machines and Pacific Fusion are now customers.
The fresh capital funds an AI harness that lets engineers use frontier models on sensitive data, plus FedRAMP authorization and other certifications aimed at regulated industries.
