The story
PermitFlow was founded in 2021 by YC alums Francis Thumpasery and Sam Lam to automate the construction permit application process — originally pitched as 'TurboTax for construction permitting.' By 2026 it repositioned as 'Construction's AI Workforce,' rolling out a set of five AI agents (Intake, Research, Submission, Coordination, Issuance) that push it from a workflow tool toward an agentic operations platform. The company primarily sells SaaS to contractors, home builders, and developers — it does not currently offer embedded finance products.
