GreenLite

A plan set lands. The clock starts. GreenLite changed what happens next.

Somewhere in America right now, a developer is uploading a stack of construction drawings for a new pharmacy, a drive-thru, or a few hundred homes. A few years ago, those drawings would have disappeared into a municipal queue and resurfaced 90 to 120 days later, scarred with red-line corrections. Today, GreenLite's software reads them first - flagging code violations before a human reviewer ever opens the file.

GreenLite is a construction technology company that does something quietly radical: it lets approved experts, backed by AI, perform official code-compliance review instead of the city. The company calls it Private Plan Review. The rest of the industry calls it the thing they wish someone had built years ago.

Building is hard. Getting permission to build is harder.

You can pour concrete in days. You can frame a building in weeks. But you cannot start until a plan examiner - often one of a handful in an understaffed department - confirms your drawings meet thousands of pages of code. That review is the bottleneck. It is invisible on a balance sheet and ruinous on a schedule.

The wait is not just slow; it is unpredictable. The same plan set can clear in a month in one county and stall for a season in the next, and there is rarely a number to call that will tell you which. For a national brand trying to open 200 locations a year, that uncertainty compounds into millions in carrying costs and missed openings. Bureaucracy, it turns out, is expensive even when it is free.

Two delivery-logistics guys decided the permit was a routing problem.

GreenLite was founded in 2022 by James Gallagher and Ben Allen, who had been executives at the rapid-delivery company Gopuff. They came from a world obsessed with shaving minutes off a process. Then they looked at construction and found a process measured in months, mostly spent waiting.

Their bet was contrarian. Most software startups would have built a tool to help cities review plans faster. GreenLite went further: if the public queue is the bottleneck, route around it. Let licensed third-party experts - architects, engineers, planners - perform the official review under jurisdiction approval, and give them AI that already knows what each jurisdiction will flag. Privatize the slowest step, but keep it accountable.

A plan examiner's brain, turned into software (and a service)

GreenLite is not just a model that says "this looks wrong." Its edge is a growing library of jurisdiction-specific compliance comments - the accumulated judgment of plan examiners, captured as structured data. The AI, called LiteTable, ingests a plan set, finds violations, and drafts the comments and response letters in the language each jurisdiction expects. Atlas, the dashboard, lets a portfolio owner watch every project's status in real time.

The pitch is a number. Here's the number.

A faster permit is a claim. A schedule is evidence. GreenLite says it compresses the typical review window from roughly 90-120 days down to 21-45 - a reduction of up to 75% on Fortune 500 projects. Walgreens, O'Reilly Auto Parts, and TD Bank are among the brands routing work through it.

Make compliance fast, predictable, and boring

GreenLite's stated mission is to combine AI with the expertise of architects, engineers, and planners so builders and public agencies can move projects forward in days instead of months. The deeper ambition is to make plan review predictable - to turn a black box into a process with a number attached.

It is a strange thing to aspire to: making one of construction's least glamorous steps so reliable that nobody thinks about it. But that is the tell of good infrastructure. You only notice it when it fails.

If you want more housing, faster, this is the unglamorous lever

Every conversation about America's housing shortage, its EV-charging buildout, its data centers and warehouses, eventually hits the same wall: you cannot build what you cannot get approved. GreenLite is now aiming its compliance engine at lodging, logistics, clean energy, and residential - the categories where the permit gap is most expensive.

Back to that developer uploading drawings for a few hundred homes. In the old world, the file vanished into a queue and the project waited a season. Now the software reads it the same afternoon, flags the three things a county will object to, and the licensed reviewer signs off in weeks. The drawings still have to be right. The difference is that being right no longer means waiting in line to find out.

The light, finally, is green.
