Founded in 2023 by mechanical engineer Pari Singh, Flow Engineering provides cloud software that turns hardware product requirements into a dynamic, continuously updated system rather than static documents. The platform is already used by next-generation manufacturers such as Rivian, Joby Aviation, Astranis, and Radiant to coordinate multidisciplinary design decisions and accelerate iterative hardware development. Singh originally created the core technology to aid rocket-engine design, and he positions Flow as critical infrastructure for the converging worlds of hardware and software. By making requirements a “living, breathing nervous system,” the company aims to shorten development cycles and improve safety for increasingly complex physical products. Sequoia managing partner Roelof Botha has joined the board, underscoring investor conviction in Flow’s potential to become a foundational layer for modern hardware engineering. While no revenue or user counts were disclosed, the company’s customer roster and rapid fundraising suggest early commercial traction. Singh ultimately envisions Flow playing a key role in efforts such as planetary exploration and global decarbonization, areas where faster hardware innovation is essential.
