Secure messaging provider with financial partner

09.2020: The fund of Afinum invests in Threema GmbH. Together with the founders, who will retain a significant share in the business, Afinum is going to support the continuation of the strong historic growth.  In partnership with Afinum, the company is striving to further strengthen its market position as the leading European secure messenger for corporate and private customers.

Threema (, based in Pfäffikon (Switzerland), is a leading European provider of secure messaging for private customers, organizations and corporates. Threema consistently focuses on data security and customer privacy. Different to other commercial messaging solutions, Threema’s software neither stores metadata nor chat content centrally. Threema’s B2C solution is used by customers in over 90 countries, while the B2B corporate messaging solution Threema Work has become the market leader in the DACH region and is used by numerous DAX 30 companies, administrations, NGOs and educational institutions.

Threema was founded in 2014 by software engineers Martin Blatter, Manuel Kasper and Silvan Engeler, who will continue to lead the company. Through the partnership with Afinum, Threema lays the foundation for continuity and gains additional resources to grow beyond the German-speaking part of Europe. Threema is continuously improving its software product and adding new features, in order to enhance customer experience while providing the most secure messaging solution. Through an innovative multi-device solution, to be launched over the coming months, customers are going to be able to use Threema on several devices in parallel, without leaving traces of personal data on servers. Additionally, Threema is going to become fully open source, which allows anyone to independently review Threema’s security and verify, that the published source code corresponds to the downloaded app.
