PermitFlow
AI agents that automate construction permitting from jurisdiction research to final approval.
About
PermitFlow is an applied AI platform that automates the slow, manual permitting process for builders across the United States. Its AI agents handle jurisdiction research, application preparation, submission, and real-time tracking, trained on a proprietary dataset of over 12 million municipal data points. Founded in 2021 in San Jose and now headquartered in New York City, the company went through Y Combinator's Winter 2022 batch, raised $5.5 million in seed funding, a $31 million Series A led by Kleiner Perkins, and a $54 million Series B led by Accel, with total funding over $90 million from investors including Initialized Capital, Felicis, and backers from OpenAI, Google, Procore, and Zillow.
The platform expanded to all 50 US states, launched PermitAI for automated plan review in 2025, and integrates with Procore. It counts Lennar, Amazon, and Dick's Sporting Goods among customers and reports powering over $20 billion in construction value. Builder outcomes claimed by the company include up to 60 percent shorter timelines, 90 percent less administrative workload, and 5x ROI, figures that come from the provider and should be read as marketing. PermitFlow describes itself as building construction's AI workforce, extending from permitting into inspections and compliance management.
