AboutDenver

I build AI for Denver’s residential agents.

One person, one city, one industry. The niche is the point.

Before this I shipped backend infrastructure at a Y Combinator startup — the unglamorous systems that have to work every time or someone notices. The throughline: take a workflow someone runs by hand and reduce it to a phone call or a single button. Real software for the person doing the work, not a dashboard for the person buying it.

I live in Denver and I work in Denver. Cherry Creek, RiNo, Wash Park, the Front Range comp pools. The market is specific enough that the AI built for it has to be specific too. A reactivation script tuned for a Phoenix iBuyer book is the wrong script for a Wash Park sphere of 600 names.

Pricing floors at $1,500 for a scoped pilot. Most engagements run an audit, a working demo on your data, then a build. The three demos on the home page are the shape of the work.

No pitch — just where AI plausibly fits.
