A software company that reads city hall so builders don't have to.

Somewhere right now, a permit is sitting in a queue. A contractor is refreshing a municipal portal that looks like it was built in 2004. A six-figure crew is standing around because a single form went to the wrong department. This is the part of construction nobody puts in the brochure - and it is exactly where PermitFlow lives.

PermitFlow is a New York company with roughly 110 people and an unglamorous obsession: the paperwork that stands between a drawing and a groundbreaking. Its platform deploys a roster of AI agents that research local rules, prepare applications, file them, chase down status, and manage the inspections and licenses that follow. The pitch is not that PermitFlow pours concrete. It is that PermitFlow clears the path so someone else can - faster.

"We've earned their trust by delivering real results."

- Francis Thumpasery, Co-founder & CEO

As of late 2025, the company says its software has powered more than $20 billion in construction value across over 7,000 jurisdictions. In December it raised a $54 million Series B led by Accel. That is a lot of attention for a problem most people never think about - which is precisely the point.

Construction's quietest killer is a filing cabinet.

The construction industry is worth around $1.6 trillion. You would expect a market that large to have solved its administrative plumbing. It has not. By the company's account, 77% of developers report permitting delays, and San Francisco alone can average something close to 33 months for an approval. Almost three years - to get permission to build something already designed and funded.

The trouble is that "the permit process" is not one process. It is thousands of them, one per jurisdiction, each with its own forms, fees, reviewers, and unwritten preferences. A builder operating in ten cities is, in effect, learning ten bureaucracies at once. Expediters have made a living navigating this by hand for decades. It works, in the way that fax machines work.

Permitting was the last analog frontier in a trillion-dollar industry - so naturally, almost no one was rushing to fix it.

YesPress · on why the problem stayed open

Two founders who lived the pain, then priced it.

PermitFlow was founded in 2021 by Francis Thumpasery and Samuel Lam. Thumpasery, the CEO, came from a Stanford business background by way of investing and a stint at McKinsey. Lam, the CTO, was an engineer at Uber and a Harvard graduate. On paper, an unlikely pair to fall in love with municipal forms. In practice, exactly the kind of people who look at a 33-month approval cycle and see a product.

Their wager was specific. Permitting felt like chaos, but chaos at scale is just data nobody has bothered to collect. If you could map how thousands of local governments actually behave - which forms, which sequence, which reviewer wants what - you could turn an artisanal headache into software. The early shorthand the press settled on was "the TurboTax for construction permitting," and it stuck because it was honest: take a dreaded annual ritual and make it fill itself out.

"Chaos at scale is just data nobody has bothered to collect yet."

The PermitFlow thesis, in one line

The investors agreed in stages. Initialized Capital led a $5.5 million seed in 2023. Kleiner Perkins led a $31 million Series A in early 2024. Then Accel led the $54 million Series B in December 2025, with Kleiner Perkins, Felicis, Initialized, Altos Ventures, and Y Combinator returning. Total raised: about $90.5 million for the unsexiest corner of construction.

A team of AI agents that never asks for a lunch break.

Strip away the branding and PermitFlow is a platform with a memory: a proprietary dataset of more than 12 million municipal data points describing how local governments actually process permits. On top of that sits a suite of specialized agents, each handling one stage of a workflow that used to require a very patient human.

Permitting
The core. Researches the authority having jurisdiction, prepares the application, submits it, and tracks status across cities so nothing rots in a queue unnoticed.
Inspections
After approval. Schedules and manages inspections and closeouts - the unglamorous tail end where projects quietly stall.
Licensing
Staying legal. Tracks and renews contractor licenses and registrations across states and municipalities.
AI Agents
The crew. Intake, Research, Submission, Coordination, and Issuance agents each own a step - so the work moves even when the office lights are off.

YesPress · on what PermitFlow actually sells

The numbers builders can feel.

Claims are cheap in software. PermitFlow's defense is its customer list and a few metrics that translate directly into payroll. The company reports approvals roughly 2.5 times faster and an estimated 5x return for builders who use it - the kind of figures that matter when a delayed permit means an idle crew. Named customers include Lennar, Amazon, IKEA, Toll Brothers, NVR, GAF, Service Experts, and Dick's Sporting Goods.

There is also the matter of distribution. PermitFlow shows up inside Procore's construction-management marketplace, which means it can sit where builders already plan their work rather than asking them to log into one more tab. For software whose whole value is removing friction, meeting customers where they are is less a strategy than a requirement.

Make pre-construction seamless.

The company states its purpose plainly: make pre-construction seamless, so builders can start projects faster and with more confidence. Behind that is a bigger argument about housing. When approvals take years, fewer things get built, and the things that do get built cost more. PermitFlow frames its work as chipping at that - not by changing the law, but by making compliance with it dramatically less painful.

Internally, the company runs on five values it actually names: Customers First, Team Player, Ownership, Urgency, and Thrive on Change. The roster is backed by founders and operators who passed through OpenAI, Google, and Zillow - people who, presumably, also once waited too long for something to get approved.

"Make pre-construction seamless, empowering builders to start projects faster with confidence."

- PermitFlow, on what it's for

The boring layer everything else waits on.

The next stretch is about widening the lane. With the Series B, PermitFlow plans to extend its agent suite deeper into inspections and license management and to grow its team against rising demand. The competitive field runs from legacy permit-expediting services to government-software vendors like Accela, Tyler Technologies, and OpenGov - and to the broad construction-tech platforms a builder already uses. PermitFlow's bet is that owning the permitting layer specifically, with the data to back it, is a defensible place to stand.

There is a real question hanging over every agentic-software company in 2026: how much of this can run without a human checking the work? Permitting is unforgiving - a wrong filing is not a typo, it is weeks. PermitFlow's answer so far has been narrow agents on top of a deep dataset, which is a more sober posture than most of the category.

Come back to that permit sitting in a queue. The contractor refreshing the 2004-era portal. The crew standing around. In PermitFlow's version, the form was filed correctly the first time, by an agent that knew which department wanted it, and the status updates itself. The crew is not standing around. They are building. That is the whole company, in one scene - the part of construction nobody puts in the brochure, finally moving at the speed of everything else.
