Flow Engineering Secures $50M to Accelerate Hardware Development

The round was co-led by Antonio Gracias of Valor Equity Partners and Gavin Baker of Atreides Management, with participation from Sequoia Capital and individual investors including Formula 1 champion Nico Rosberg. Roelof Botha joins the company’s board as an independent director as part of the financing. The startup’s platform uses AI agents to track design changes, propagate updates across mechanical and electrical systems, and verify compliance with millions of engineering requirements in real time.

Flow has seen rapid adoption among firms pushing the boundaries of aerospace, automotive, and defense. Rivian, for instance, scaled its internal use from 40 to 1,500 users in seven months, with engineers now executing millions of API calls weekly. According to Pari Singh, Flow’s founder and CEO, 96% of the company’s customer base has arrived via inbound interest. The new funding will support the development of secure AI harnesses for sensitive technical data, the pursuit of FedRAMP certification, and an expansion of the engineering team to meet increasing demand for automated systems verification.
