Valor, Atreides, and Sequoia back AI startup Flow Engineering at $750M valuation

Flow Engineering, a startup applying AI agents to hardware design workflows, secured backing from Valor, Atreides, and Sequoia at a $750M valuation. Sequoia’s Roelof Botha also joined as an angel investor and board member.

The deal highlights growing investor interest in using AI to modernize engineering-heavy industries beyond software. If Flow can reduce iteration time in hardware design, it could become part of a broader shift toward AI-assisted product development in manufacturing, aerospace, robotics, and electronics.
