America’s $1.6T construction industry faces a critical infrastructure crisis: while housing starts reached 1.43M units in mid-2025, 77% of developers report permitting delays, with cities like San Francisco averaging 33 months just to secure approval. This pre-construction bottleneck has compounded a 4.7M housing unit shortage, pushing median home prices up $88K since 2020 while construction timelines stretch beyond 300 days from permit to final inspection in many markets. PermitFlow addresses this systemic breakdown with AI agents that automate the entire pre-construction workflow, from jurisdiction research through final approvals, turning what typically takes months into days. Since launching in 2021, the platform has powered over $20B in construction value nationwide, drawing on a proprietary dataset of 12M+ municipal data points to deliver 2.5X faster permit approvals and 5X ROI for builders. With leading construction teams including Lennar, Amazon, and Dick’s Sporting Goods now relying on the platform to navigate 7K+ jurisdictions, PermitFlow’s approach demonstrates how intelligent automation can unlock housing supply at scale where manual processes have failed.

What inspired the start of PermitFlow?
Samuel Lam (cofounder) and I both experienced the delays, complexity, and inefficiencies of construction permitting firsthand. Working closely with contractors, developers, and local AHJs, our team saw how fragmented systems and manual workflows added overhead and slowed down projects before they even began. These inefficiencies made pre-construction more expensive and unpredictable, becoming a major bottleneck to housing, infrastructure, commercial development, and home services. PermitFlow was built to streamline the entire pre-construction process, starting with fast, effortless, and predictable permitting.

What advice can you offer companies in New York that do not have a fresh injection of capital in the bank?
Every company’s situation is different, so I don’t want to over-generalize. What’s been true for us is treating capital as the result of building a strong, enduring business. We do this by staying close to customers, controlling burn, and focusing on real value creation. If you do that consistently, fundraising becomes the byproduct.
Where do you see the company going now over the near term?
Demand from builders is stronger than ever. We plan to grow our suite of AI agents and expand our team to meet the demand for our platform, empowering builders to accelerate construction projects from concept to reality.
What’s your favorite winter destination in and around the city?
