The Property OS

Every property,
one system.

One calendar across every channel. One inbox in every language. One system for short-term, long-term, and corporate — the properties you run today, on tools that finally talk to each other.

Early access for operators running mixed portfolios.

The problem

Five logins. Three calendars.
One overstay you heard about too late.

What it is

One calendar, every channel.

Airbnb, Booking.com, Vrbo, direct, and corporate — synced both ways, so a booking on one closes the dates on all of them. No double-bookings, no calendar you forgot to update.

One inbox, every language.

Every guest message, from every platform, in one thread — translated as it lands, answered in their language. Nothing slips between apps.

One system, every property type.

Short-term lets, long-term tenancies, and corporate stays in the same place. Stop changing software every time you change rental type.

The threshold

Light under a door. The moment of arrival the whole system is built around.

What it replaces

Everything your stack does. In one system.

The tools you pay for today each do one slice well and ignore the rest. Seraia runs the whole operation from one place — and keeps going where the others stop.

Most tools sit on top of your PMS. Seraia replaces it.

The moat, quietly

Know who arrived. Know when they should leave. Without a single camera indoors.

Physical intelligence senses arrivals and overstays at the threshold — privacy-first, consent-first, never surveillance.

Built for the whole portfolio
Early access

We’re opening access to a small group of operators first.

We’re building Seraia with people running real mixed portfolios. Join early, help shape what we build, and switch on the tools that replace your stack — one by one, as we open them.
