Fixed-scope AI builds for real estate

The buyer who messages at 9pm shouldn’t have to wait until morning.

We build an AI concierge on your own listings — it answers after-hours inquiries, shows matching homes, and never sleeps. Fixed scope. Fixed price. Live in 30 days.

Concierge live in production on real listings

Proof, not a demo

Built and measured on a live platform.

We do not demo on toy data. The concierge below runs on a client’s real inventory, against real buyer traffic.

Client anonymized by agreement: a California coastal real-estate platform.

Quality enforced in CI
Video quality is a tested invariant. Re-encodes must re-pass or the build fails.
  • Progressive media, by designImage rungs climb 960w to 1920w; video loads when the browser is idle; data-saver devices get the poster and stop.
  • Zero third-party requestsSelf-hosted variable fonts, immutable caching at the edge — no font CDN on the critical path.
  • Guarded by testsA unit and structural battery plus end-to-end browser tests and Lighthouse floors. The build fails before a regression ships.
How it works

Three steps. One bounded outcome.

No open-ended discovery, no hourly meter. Each step ends in something you can hold.

Map your listings and buyer journey

Where your inventory comes from, what is stale or missing, and where a high-intent visitor drops off. The after-hours lead becomes a number, not a hunch.

Build the assistant on your data

A production concierge on your own listings — answering, matching, and scheduling in your brand’s voice. The workflow goes live, not into a slide deck.

Monitor and optimize

We watch real conversations, fix what falters, and tune matching against the leads that actually convert.

The ladder

Fixed scope. Fixed price. Nothing unfunded.

Start with the cheapest yes, or go straight to the build. Every rung names its deliverable and its acceptance test up front.

A 20-minute call is enough to size the opportunity — and to say no if the math isn’t there.
