stayi
Detailed presentation

stayi is an AI concierge for hotels that lives on the guest's own phone. Guests scan a QR code or open a link, with no app to download, and then type, talk, or talk face to face with its avatar, in their own language, about the hotel and the area. stayi does not stop at answers: it sorts requests out. Any request reaches the right person at the hotel, and for what the hotel chooses, stayi acts itself. It books the table, arranges the transfer, books the massage. Others tell guests how to solve a problem. stayi solves it.

The problem

Throughout a stay, guests have questions and needs: where to eat tonight, a taxi at 5 a.m., extra towels, a massage, a later checkout. Much of this still goes through reception or gets lost between printed guides, apps and messages. At busy moments guests wait, the team answers the same questions again and again, and a request in a foreign language is easy to misunderstand, while 71.5% of guests in Greek hotels come from abroad and the sector is short of 36,145 staff (ITEP, 2025). Many digital tools only inform: they give the guest a phone number or a link and leave the rest to the guest. As a result, many requests never happen. The table is not booked, the spa stays empty, and a small problem becomes a complaint on Booking after the guest has left. Hotels lose service quality and revenue in that gap.

Our proposal

stayi gives hotel guests a concierge on their own phone that acts instead of just explaining.  Guests scan a QR code or open a link, with no app to download, and type, talk, or talk face to face with its avatar, in their own language, about the hotel and the area. Any request reaches the right person at the hotel. For what the hotel chooses, stayi calls or books and sorts it out itself: a table for tonight, a taxi or transfer, a spa treatment. A complaint reaches the hotel first, while the guest is still there, not on Booking after they leave. For the hotel there is nothing to install and no staff training: it sends its services, prices and partners, and it is live the day it signs. stayi works with the hotel's PMS, or without one. Last summer: over 7,000 guest conversations, in 13 Greek hotels.
