From pre-arrival to checkout. And everything between.

Visual timeline

Arrivals, departures, cleaning, maintenance, activities — see your entire day at a glance. Color-coded status shows what needs attention.

Pre-arrival flow

Automated welcome messages. Collect flight details, transfer preferences, special requests. Guest arrives — you're already prepared.

One-click dispatch

Send transfer requests to vendors instantly. No more copy-pasting details across WhatsApp groups. They confirm, you see it.

Housekeeping sync

Cleaning schedules tied to check-outs and check-ins. Your team sees what's due, marks complete. No more radio silence.

Maintenance tracking

Log issues, assign technicians, track resolution. Guest reports broken AC — it's on the timeline until fixed.

Luggage & storage

Early arrivals, late departures. Assign a team member, they see exact arrival time, location, guest details. You monitor — they execute.

Vendor network

Your trusted partners on the same platform. Transfers, tours, boat rentals. They see requests, confirm availability, assign drivers.

Built for Greece

Islands and mainland. Flights, ferries, helicopters. Multiple pickup points. Group arrivals. We understand Greek hospitality logistics.

Launch your island

Thereos activates territory by territory. We start where demand exists. If your island or region isn't live yet, you can bring it online.

Receptionist

"I used to start every morning with 30 minutes of WhatsApp archaeology. Now I open Thereos and see exactly what needs my attention."

Danae K. · Front Desk · Santorini

Vendor

"I used to hold off accepting transfers because I never knew if my dispatcher was available or already committed. Now I see my whole fleet in one place."

Vassilis T. · Island Transfers · Santorini

Property Manager

"One glance: transfer confirmed, villa cleaned, jacuzzi checked, linen ready, welcome drink prepared, luggage guy waiting at the port. Guest lands — everything's green."

Kostas B. · Villa Portfolio · Santorini

Join the Santorini beta

We're inviting a small group of properties and transport companies to help shape Thereos before public launch. Free during beta. No commitment.

Limited to 22 properties or property managers + 4 transport companies · Launching February 2026

Free during beta. Future model: pay-as-you-go + seasonal monthly options. Winter isn't summer — your pricing shouldn't be either.
