Flow Engineering raised $50 million in Series B funding at a $750 million valuation to expand its agentic AI platform for hardware development. The round was co-led by Antonio Gracias, founder of Valor Equity Partners, and Gavin Baker, Managing Partner at Atreides Management. Sequoia Capital also participated alongside Human Capital, Evantic, SV Angel, Odyssey, and EQT.
Additional investors included Hugging Face co-founder Thomas Wolf, Mercedes-Benz CIO Jonas von Malottki, and Formula 1 champion Nico Rosberg.
Sequoia’s Roelof Botha joined Flow’s board as an independent director and personally invested in the company.
Flow develops AI agents designed to help engineering teams manage changes across mechanical, electrical, and software systems.
The platform continuously tracks design changes, propagates updates across teams, and verifies requirements and constraints.
Flow’s goal is to reduce hardware iteration cycles from months to days.
Since its Series A, Flow has added customers including General Motors PPU, Rivian and Volkswagen joint venture RV Tech, Anduril, Stoke Space, Intuitive Machines, and Pacific Fusion.
Existing customers also include Rivian, Joby Aviation, Astranis, and Radiant Industries.
Usage at Rivian grew from approximately 40 to 1,500 users in seven months.
Flow plans to use the financing to build what it describes as an AI harness for hardware engineering.
The company will expand review, branching, evaluation, and security capabilities while growing its AI and systems engineering teams.
Flow also plans to pursue FedRAMP authorization and other certifications for regulated customers while expanding its sales organization.
KEY QUOTES:
“Every hardware company now has to decide how fast it will adopt AI, and those that move first will win their markets.”
“Flow has emerged as the de facto platform for agentic hardware. Ninety-six percent of our customers come to Flow inbound.”

“Flow is building the OS on which physical products are specified, verified, and eventually designed, substituting software for scarce engineering capacity as hardware programs become increasingly more complex.”
Gavin Baker, Managing Partner at Atreides Management
