In a round led by Accel, with participation from Kleiner Perkins, Felicis, and others, the company is unblocking construction teams and driving down costs along the entire pre-construction process
NEW YORK–(BUSINESS WIRE)–PermitFlow, the nation’s leading AI platform for construction, today announced it has raised $54 million in Series B funding led by Accel, with participation from Kleiner Perkins, Felicis, Initialized Capital, Altos Ventures, Y Combinator, and existing investors. The company is building construction’s AI workforce, giving builders a faster, more predictable path from plan to project.
Whether unblocking permitting delays in LA wildfire reconstruction or driving down the cost of new housing, PermitFlow is tackling the bottlenecks that hold America’s builders back. Since launching in 2021, its AI platform has automated some of construction’s most complex workflows — powering more than $20 billion in construction value nationwide. Trusted by leading construction teams including Lennar, Amazon, and Dick’s Sporting Goods, PermitFlow’s AI agents orchestrate every phase of pre-construction, from early design and planning to final approvals and groundbreaking.
Builders using PermitFlow’s platform have shortened timelines by up to 60%, reduced administrative workloads by 90%, and achieved 5× ROI. These outcomes are powered by PermitFlow’s proprietary dataset of over 12 million municipal data points, which continuously train its AI agents and automation models.
“Builders are the backbone of America. They put families in homes, build critical infrastructure, and shape our communities. Yet the systems behind that progress are decades old,” said Francis Thumpasery, Co-Founder & CEO of PermitFlow. “We’re changing that by bringing AI to construction and empowering builders to build without barriers.”
With this new round of capital, PermitFlow will accelerate product development across its growing suite of AI agents, including modules for permitting, inspections, and license management, and expand its team to meet rising demand from builders nationwide. The company has already assembled a world-class team of engineers and product leaders from Meta, Google, Uber, Lyft, Stripe, and Canva, and will continue hiring top talent to advance its mission to make pre-construction seamless and empower builders to start projects faster with confidence.
“As infrastructure and housing projects accelerate globally, there’s so much compliance, regulatory and legal overhead to manage,” said Vas Natarajan, Partner at Accel. “PermitFlow entirely redefines that complex, time-consuming work with AI. We’ve been impressed by the team’s clarity of vision and are glad to be part of their journey.”
