The financing round was co-led by Antonio Gracias of Valor Equity Partners and Gavin Baker of Atreides Management, with participation from Sequoia Capital, Human Capital, and EQT. The capital infusion arrives as major players in the aerospace, automotive, and defense sectors—including Rivian, Anduril, and Stoke Space—increasingly rely on Flow to manage the cascading design changes inherent in modern hardware projects.

Flow’s platform functions as an automated system of record that tracks engineering requirements and verifies system integrity in real-time. By connecting CAD, code, and simulation data, the company’s AI agents propagate updates across multidisciplinary teams, a process previously handled through manual, error-prone coordination. Rivian, for instance, expanded its usage of the platform from 40 to 1,500 engineers in seven months, now processing millions of API calls weekly.

Founder and CEO Pari Singh intends to deploy the new funding to enhance the platform’s security protocols for sensitive engineering data, pursue FedRAMP authorization, and expand the company’s engineering and sales teams. As hardware programs grow in complexity, the company aims to position itself as the primary operating system for physical product development, effectively substituting software-driven automation for scarce human engineering capacity.
