San Francisco-based Flow Engineering has raised $50 million in a Series B funding round, reaching a valuation of $750 million. The investment is set to support the company's goal of making hardware development move with the speed and flexibility traditionally associated with software.
The round was co-led by Antonio Gracias of Valar Equity Partners and Gavin Baker of Atreides Management. Sequoia Capital, which led Flow Engineering's previous funding round, also participated. Former Sequoia partner Roelof Botha joined the company's board following his individual investment.
AI agents for faster engineering cycles
Founded three years ago, Flow Engineering develops AI agents designed to streamline complex hardware design workflows. Its platform connects CAD files with product specifications, simulation outputs and testing data, helping engineering teams identify alignment gaps and iterate more efficiently.
The company's customer base includes organizations working across advanced mobility, aerospace and industrial technology, such as Rivian, Joby Aviation, General Motors PPU, RV Tech and Stoke Space.
By bringing design requirements, simulations and validation processes into a more connected AI workflow, Flow Engineering aims to reduce friction in building physical products. This approach could help shape a future in which engineering teams test, refine and launch hardware innovations at a significantly faster pace.
