🚀 About PermitFlow

PermitFlow is redefining how America builds. Pre-construction remains one of the most broken and manual parts of the $1.6T construction industry, causing massive delays, wasted capital, and lost opportunity across the built world. Our AI workforce delivers unprecedented speed, accuracy, and visibility to pre-construction — accelerating housing development, enabling clean-energy projects, and driving economic growth in communities nationwide. To date, we’ve powered over $20B in real estate development, helping builders and contractors move faster, reduce risk, and scale with confidence.

We’re entering hypergrowth with clear product-market fit and a world-class team from top AI and construction companies. We’ve raised over $36.5M from Kleiner Perkins, Initialized Capital, Y Combinator, Felicis Ventures, and Altos Ventures, alongside backers from OpenAI, Google, Procore, ServiceTitan, Zillow, PlanGrid, and Uber. We are on a mission is to modernize how the built world operates.

Our HQ is in New York City with a hybrid schedule (3 in-office days per week). Preference for NYC-based candidates or those open to relocation.
