One AI core · four pillars · built for Greek hospitality
Every booking, a guest you know.
Xenios turns every guest who books through a middleman into a known, direct customer from the first stay. A guest app, a control centre and one AI core, connected to your PMS, booking engine and channel manager.

Five problems. One platform.
The Greek property, especially the small and mid-sized one, runs with five structural weaknesses. Today's tools solve one at a time. Xenios treats them as one.
Without Xenios
- ✕60 to 80% of bookings come through platforms charging 15 to 25%, and you never meet the guest first
- ✕PMS, booking engine, channels, email and reviews each hold one piece of the guest
- ✕The stay is room, breakfast, pool. The island's story goes untold
- ✕Every manual task (check-in, questions, bookings) hits a team you can't fully staff
- ✕Weather and delays reach you through a complaining guest
With Xenios
- ✓Every guest becomes a known, direct customer from the first stay
- ✓One 360° profile across every system, nothing typed twice
- ✓AR, stories and quests make the destination part of the stay
- ✓Check-in, keys, answers and bookings run themselves
- ✓Xenios reacts to weather and delays before the guest asks
[02]
One AI core. Four pillars.
The AI core takes data from every source, turns it into knowledge about each guest and decides in real time: which message, to whom, when; which price; which content; which action. The four pillars are four ways the same knowledge becomes action. Tap any part to explore it.

A day with Xenios.
Anna from Munich, 34, books 5 nights for September. Watch her stay in 90 seconds, or read it step by step below.
1:28
01 · Booking
Xenios knows her from her first visit: German-speaking, a couple, searched for "sea view" and "kitchen". Her profile starts.
02 · One week before
In German: a "Tastes & Sunsets" stay scenario, a 360° tour of her room and an invitation to check in. Done in 3 minutes.
03 · Arrival day
Her flight is 50 minutes late. Xenios knows before she does, updates the driver and tells her: "We'll be waiting at 15:10." Her key activates.
04 · In the room
She scans the QR: the building's story in AR, tonight's menu, today's riddle from the quest "Secrets of the island".
05 · Day 3
The wind cancels her boat trip. Before she is disappointed, she gets a cooking class, a sheltered beach and a sunset taverna. She books two.
06 · Departure
One-click checkout, the key deactivates, her points land in her wallet, redeemable at the hotel and partner shops. A thank-you in German follows.
07 · February
Xenios predicts that German couples book September in February, and sends her a return offer. Direct, with no middleman.
[05]
Know who's arriving, before they land.
In the control centre: today's arrivals on a timeline, next to their flights and ferries. Who is ready, who needs a nudge, what changed.
