Hardware's AI moment: Flow Engineering lands $50M Series B at $750M valuation

Flow Engineering has raised a $50M Series B at a $750M valuation, with Antonio Gracias of Valor Equity Partners and Gavin Baker of Atreides Management co-leading the round. Sequoia Capital, which led Flow's Series A, is doubling down, and Roelof Botha is participating personally. New investors include Thomas Wolf of Hugging Face, Formula 1 World Champion Nico Rosberg, Mercedes-Benz CIO Jonas von Malottki, Human Capital, and Evantic.
Flow builds AI systems-engineering agents for hardware teams. The agents monitor changes across CAD, Git, simulations, and documentation, then run impact analysis, flag conflicts, and detect requirement failures — compressing hardware development cycles from months to days, according to the company. Founder and CEO Pari Singh describes the moment as hardware's AI moment, arguing that AI has already transformed software development and that hardware engineering is next.
The startup says it is now the default platform for requirements and verification for frontier hardware teams, counting Anduril, Joby, Stoke Space, and Rivian as customers. It also names General Motors PPU and RV Tech, the Volkswagen-Rivian joint venture, as industry giants reshaping their core development practices with Flow. In the past 12 months, Flow says it has scaled its San Francisco headquarters, launched Flow v3, deployed Systems Engineering agents in live hardware programs, and won over leaders in space, aerospace, autonomy, defense, and energy.
'When I became an engineer, I wanted to invent. In reality, 90% of the day to day execution work (CAD, excel, sim) was digital manual labour. That's about to flip,' Singh wrote in the announcement. Flow is hiring across AI and systems engineering as it looks to push the shift forward.
