Case Study: Hotel Estrel Berlin reaches all employees with Threema Work

Hotel Estrel Berlin - Customer Case Study

The Hotel Estrel Berlin, Germany's largest hotel, faced the challenge of reaching its non-desk employees who lacked company email addresses. To ensure everyone could be contacted, they turned to the vendor Threema and implemented its Threema Work solution for secure messaging.

Threema provided a flexible and accessible platform that was quickly adopted across all departments for group chats, voice calls over Wi-Fi, and sharing files. The solution successfully ensured full communication coverage for all staff, with employees using the app daily. Hotel Estrel Berlin also valued Threema Work for its strong security and privacy protections, including Swiss-based servers and a no-metadata-collection policy.
