| Date | Stage | Investors | Raised | Valuation | Deal Summary |
|---|---|---|---|---|---|
| Sep 2026 | Series B | Atreides Management (lead); Valor Equity Partners (lead); SV Angel; Nico Rosberg; Evantic Capital; Thomas Wolf; Human Capital; Sequoia Capital; Odyssey Ventures; EQT Ventures | $50M | $750M | Flow Engineering raised a $50 million Series B at a $750 million valuation in a September 30, 2026 financing led by Valor Equity Partners and Atreides Management, with Sequoia Capital participating alongside Human Capital, Evantic, SV Angel, Odyssey, EQT, and individual backers Thomas Wolf, Jonas von Malottki, and Nico Rosberg. The round was structured as primary venture financing for the hardware-development software company, with the stated use of proceeds centered on scaling its agentic platform for hardware engineering, expanding product capabilities, and supporting sales and certification efforts. The financing followed Flow Engineering’s earlier Series A led by Sequoia Capital and was framed around accelerating hardware iteration to software-like speed. The company positions its platform for teams building complex hardware programs, and the new capital was tied to hiring across AI and systems engineering, improving review and evaluation tools, advancing compliance work, and expanding go-to-market execution. Flow Engineering is described as an agentic platform for hardware development serving live programs at companies including Rivian, Anduril, Joby, and Stoke Space. |
| Oct 2025 | Series A | Sequoia Capital (lead); David Helgason; John Collison; Odyssey Ventures; Patrick Collison; Kyle Parrish | $23M | - | Flow Engineering is a San Francisco-based startup founded in 2023 by Pari Singh, offering a modern platform for hardware engineering that enables agile, iterative development for complex systems like reusable rockets, autonomous aircraft, self-driving cars, and humanoid robots. The platform acts as a 'living, breathing nervous system' for requirements management, integrating with CAD, simulation, and PLM tools to connect changes, decisions, and iterations across cross-functional teams, replacing legacy tools and manual processes. It serves high-profile customers including Rivian, Joby Aviation, Astranis, and Radiant Nuclear in sectors like aerospace, automotive, space, defense, nuclear, and robotics. On October 14, 2025, Flow Engineering raised a $23M Series A round led by Sequoia Capital, with participation from Odyssey Ventures, Unity founder David Helgason, Stripe founders Patrick and John Collison, EQT Ventures, and Backed VC. Sequoia managing partner Roelof Botha joined the board, and the Collisons became advisors. The funds will accelerate growth, support hiring in San Francisco (new HQ) and London, and enable next-gen hardware companies to design, build, test, and iterate as quickly as software teams. Previously, the company raised an $8.5M seed/extension in December 2022 led by EQT Ventures and a $2.5M pre-seed in October 2017 led by Acequia Capital and Backed VC, bringing total funding to approximately $31.5M-$34M. Flow has demonstrated rapid traction in two years, becoming the default platform for next-generation hardware teams, with early enterprise customers in aerospace and automotive. The CEO noted reaching profitability in February 2025 with a team of 7, and recent product updates include an AI agent and test case management features. The company faces challenges like integration complexity with evolving tools and market concentration in cyclical industries, but benefits from strong founder-market fit, top-tier investors, and product-market validation through customer adoption. |
| Dec 2022 | Seed | EQT Ventures (lead); Matt Clifford; Nathan Benaich; David Helgerson; Seedcamp; BACKED VC; Charlie Songhurst; Kyle Parrish; Kima Ventures | $9M | - | Flow Engineering raised an $8.5 million seed round on December 1, 2022, led by EQT Ventures with participation from Backed VC and angels including Charlie Songhurst, David Helgerson, Kyle Parrish, Matt Clifford, and others. The UK-based company develops software to enhance collaboration for hardware engineering teams in sectors like aerospace and automotive, acting as a GitHub-like platform for hardware by enabling constant testing, validation, and verification of complex designs. Founders from aerospace and F1 backgrounds deployed the software with early unnamed automotive and aerospace clients to address collaboration inefficiencies amid supply chain issues. The funding supports building the initial product, securing enterprise customers, and delivering a generally available solution. Flow aims to accelerate hardware development timelines, such as reducing nuclear fusion delivery by two years or EV production by 18 months, while cutting costs by 20% on carbon reduction projects. EQT Ventures highlighted the urgent opportunities in modern hardware engineering. |
