Flow Engineering Raises $50M Series B at $750M Valuation, with Continued Backing from Odyssey Ventures
The round comes as Rivian, Anduril, Joby and Stoke Space put Flow's AI agents to work in live hardware programmes
London, 12 October 2026: Odyssey Ventures today announced its continued investment in Flow Engineering, the agentic platform for hardware development, as part of Flow's $50 million Series B at a $750 million valuation. Odyssey Ventures first backed UK founder Pari Singh at Seed and followed on in Flow's Series A. This round was co-led by Antonio Gracias, founder of Valor Equity Partners, and Gavin Baker, Managing Partner at Atreides Management. Sequoia Capital, which led Flow's Series A, also participated alongside Human Capital, Evantic, SV Angel, Odyssey Ventures and EQT, with contributions from Hugging Face co-founder Thomas Wolf, Mercedes-Benz CIO Jonas von Malottki and Formula 1 world champion Nico Rosberg. Roelof Botha has joined Flow's board as an independent director and personally invested in the company.
Over the past year, AI has changed how software is developed. Flow believes the same shift is now coming to hardware, a substantially harder problem: a single design change can ripple across mechanical, electrical and software systems, all of which must still meet millions of requirements and constraints. Flow is building a platform where AI agents continuously track changes, propagate updates across teams and verify the results in seconds, with the goal of reducing hardware iteration cycles from months to days.
"Every hardware company now has to decide how fast it will adopt AI, and those that move first will win their markets," said Pari Singh, Founder and CEO of Flow. "Flow has emerged as the de facto platform for agentic hardware. Ninety-six percent of our customers come to Flow inbound."
Since its Series A last October, Flow has added General Motors PPU, RV Tech (Rivian and Volkswagen's joint venture), Anduril, Stoke Space, Intuitive Machines and Pacific Fusion as customers, joining Rivian, Joby Aviation, Astranis and Radiant Industries. At Rivian, adoption has grown organically from 40 to 1,500 users in seven months.
"We backed Pari at Seed because he combined a huge vision with extraordinary execution, and he has exceeded every expectation since," said Alastair Mitchell, Co-Founder of Odyssey Ventures. "He is exactly the kind of founder Odyssey Ventures exists to back: a UK engineer who took his company to the US and is building the category leader for how the physical world gets engineered. We're proud to keep backing Pari and the team."
Flow will use the new funding to build the leading AI harness for hardware engineering, grow its AI and systems engineering teams, pursue FedRAMP authorisation and scale its sales team to meet rising demand.
