One inbox for every account — the agent flags what needs you, handles the rest.

04Where we stop

A real pipeline, drawn honestly: what the agent publishes on its own, what waits for approval, and what goes to a person. The dotted branch is the point.

05What we stand for

Three things that shape every property system we ship, and why we build them at all.

01

Tech

AI-native, not a chatbot bolted on. Every system we ship learns and improves with data of its own.

02

Eco

Less waste, less friction. We help agencies market and manage properties built to weigh less on the planet.

03

Contemporary

Design and software as of today, not a template from five years ago.

07FAQ

Questions clients ask

01How fast can you start?

Usually within a week of the discovery call. We keep a small client roster on purpose so we can move fast when a new project starts.

02Who owns the code?

You do — full IP transfer on completion, no exceptions. It's your product, we're the ones building it.

03What's the engagement model?

Either project-based (fixed scope, fixed price) or a monthly retainer for ongoing build and maintenance. We'll recommend one after the discovery call.

04Do you sign NDAs?

Yes, happy to sign yours or use ours. Standard practice before we look at anything sensitive.

05Do you work with non-technical founders?

Most of our clients are. We handle the full stack — product, design, engineering and AI — so you don't need an in-house technical team to ship.
