El Corte Inglés is Europe's largest department store chain. The flagship store in Lisbon is always busy: shoppers, tourists, business visitors. Many of them need a quiet spot for 15–30 minutes — for a call, an online meeting, or simply to get some work done.
The model
The Silentbox Cloud booth runs as an automated service. Users book through the app, pay by the minute (Apple Pay, Google Pay or card), unlock the door and step in. It all runs 24/7 with no staff on site.
The result
The booth turned unused floor space into a revenue stream. Occupancy of 78% and over 500 bookings a month mean the equipment pays for itself in roughly six months at a footfall of 200+ people a day. It works as a reverse contract: the location provides the space, Silentbox provides the booth, and the revenue is shared.
The Cloud model is a natural fit for high-traffic public locations — shopping centres, airports, coworking spaces and business centres.
