Flow Engineering

Flow Engineering builds a requirements-management and AI-agent platform for hardware engineering teams. Its Systems Graph connects requirements, CAD, simulation, code, and test into a single system of record, and its AI agents continuously run impact analysis, check test coverage, verify compliance, and track mass, cost, and power budgets as designs change. Flow integrates with CAD, PLM, simulation, and developer tools (Onshape, GitHub, GitLab, Jira, Linear, Confluence, and more) and is used by hardware teams at companies such as Rivian, Joby, Skydio, and Isar Aerospace. The platform is backed by a GraphQL API at api.flowengineering.com secured with AWS Cognito OAuth2/OIDC, with API access included on paid plans. Flow Engineering is a portfolio company of EQT Ventures.

Flow Engineering publishes 1 API on the APIs.io network. Tagged areas include Company, Software Development, Hardware Engineering, Requirements Management, and Systems Engineering.

Flow Engineering’s developer surface includes signup flow, pricing, engineering blog, authentication, and 11 more developer resources.
