The case
Sigma Hostel opened in March 2026 as a fully self-service hostel spread across two buildings, offering individual rooms with shared bathrooms alongside nicely decorated communal lobbies and a strong social offering: ping pong, foosball, a basketball pitch, board games and a book corner.
The concept set out to give guests the social energy of a classic hostel without a staffed front desk holding it together. Check-in, check-out and everyday guest questions all needed to run smoothly across two separate entrances, with no one physically on site to answer them.
That's why hostz built the digital backbone behind the concept: self check-in for both buildings and an AI-first guest communication line on WhatsApp, always on for guests in either building.
Behind that first layer, a hostz team stood ready to step in the moment a question needed a human touch, with active revenue management running in parallel to keep the property performing from day one.
Added Value through hostz
While the client concentrated on branding and physical setup of the hotel rooms, the hostz's team functioned as enablers and hospitality experts, supporting the client's vision and facilitating the operational success of the new hotel concept.
While Sigma Hostel concentrated on the guest experience, the community feel and the amenities, hostz's team functioned as the operational layer behind the scenes.
hostz implemented its AI WhatsApp system as the property's 24/7 front line, answering standard guest questions the moment they come in.
Whatever the AI WhatsApp system couldn't resolve was escalated straight to hostz's team, who backed up self check-in across both buildings with fast, consistent replies around the clock.
hostz's revenue management team kept occupancy strong from launch, driving demand across the property's first six months in the market.
Highlights in Numbers
