Valor, Atreides, and Sequoia back the startup bringing AI agents to hardware design, with former Sequoia steward Roelof Botha joining as an angel.
Flow Engineering, which applies AI agents to semiconductor and hardware design workflows, raised a round valuing the company at $750 million. The round brought in Valor, Atreides, and Sequoia, alongside Roelof Botha as an individual investor and board member.
The deal adds to a growing cluster of startups applying agentic AI to engineering-heavy, capital-intensive industries that have historically resisted automation.
Chip design has long been a bottleneck gated by scarce engineering talent and multi-year cycles; agents that compress that timeline change the economics of who can compete in silicon. A marquee investor like Botha joining the board also signals this category is moving from novelty to infrastructure bet.
