Teamwire is a secure Business Messenger App developed for mobile collaboration and mission-critical communication.
We are a safe alternative to WhatsApp for enterprises, the public sector, and healthcare.
More than half of the German police use our secure messenger app to supplement digital radios.
The app has been specially developed for operational scenarios of the police (or fire brigade or disaster control, etc.) and can do much more:
* Optimal coordination of operations thanks to live location and alerting function.
* Real-time transmission of photos + videos.
* Secure communication (100% GDPR-compliant + ISO-certified + state-of-the-art encryption technology + full data sovereignty)
This enables the police to act faster in manhunts and missing persons cases, benefiting people in danger.
Operations during demonstrations, natural disasters, and major events can be coordinated more safely and effectively.
Our international, experienced, and full-remote teams work with agile processes. The organization focuses on good collaboration, positive results, and significant growth.
