New Ownership

At the beginning of 2026, ownership of Threema is transferred from Afinum Management GmbH to Comitis Capital GmbH. The German investment firm, which focuses on companies with a strong sense of purpose and a dedication to sustainability, will support Threema in further strengthening its position in the field of security and data protection.

For Threema users, nothing will change. Our mission, the company strategy, and the management team remain the same.
