Flow Engineering builds an AI-native requirements platform designed for hardware teams developing complex systems. The company, founded in 2023 and backed by Sequoia Capital with $23M in Series A funding, operates from San Francisco with continuing operations in London.
The platform enables hardware teams to collaborate with AI agents throughout the design, validation, and evolution of complex systems. It serves as a centralised system of record that automatically verifies changes and propagates them across the entire engineering toolchain, providing a single source of truth for teams and external partners to iterate in real time. The platform addresses a structural gap in hardware development: whilst software engineering moved to agile methodologies, hardware development remained locked in waterfall-style processes.
Flow Engineering's customers include Rivian, Joby Aviation, Astranis, Radiant Nuclear, Skydio, and Impulse Space. The company targets next-generation hardware companies building systems for space, defence, satellites, robotics, new energy, nuclear, and fusion technologies, positioning itself in a period when the American hardware industry is experiencing a renewed wave of innovation across aerospace, automotive, defence, and related sectors.
