Architects spend up to 20% of their week on code compliance. Checking should take 30 seconds.

BusinessDen, the outlet covering Denver's business and real estate scene, profiled Kestrel Labs. The piece opens where the company started: Co-Founder & CEO Marian Pulford's own permitting frustration developing in the RiNo Art District, the experience that convinced her the slowest part of getting a building approved was a software problem nobody had solved.

“Architects are spending up to 20% of their time a week doing these activities.”

The whole building, checked in about 30 seconds

The article walks through how Kestrel gives that time back. The platform plugs into the 3D design tools architects already use and checks the entire building in about 30 seconds, surfacing every error, with the code section behind it, against the roughly 80% of municipal codes that are clearly defined. The remaining 20% is interpretation, and that stays where it belongs: with the architect.

BusinessDen also captures where the company is today: several dozen customers running Kestrel across hundreds of projects, concentrated in Colorado and reaching design teams in Florida, California, New York, and Illinois, backed by a pre-seed round led by New Stack Ventures with participation from Denver Ventures and FirstMile Ventures.

On pricing, Marian was candid with the reporter: “We are not out here charging more than the software that architects use to design, but it costs more than a ChatGPT subscription.” Annual contracts, unlimited use, tiered by firm size and project types.

Built in Denver, on purpose

Kestrel is a nine-person team at 18th and California downtown, building for an industry that Denver knows well from both sides: the firms designing the city and the permitting offices approving it. Hometown coverage like this means a lot.
