Partnering with Flow: The Agile Hardware Future

• Sequoia leads Series A in Flow Engineering, a hardware requirements platform.
• Hardware renaissance underway: aerospace, automotive, defense, robotics all accelerating.
  • Incumbent tools (DOORS, etc.) built for waterfall; can’t handle modern iteration pace.
• Flow = system of record that auto-verifies requirement changes across teams.
  • Catches cross-team conflicts before they become costly physical rework.
• Founder Pari Singh (ex-hybrid rocket design consultancy) built v1 to cut weeks to hours.
• Customers: Rivian, Joby, Astranis, Radiant Nuclear — across space, defense, robotics.
• Thesis: hardware needs the agile methodology shift software got 20 years ago.
