T-Systems International GmbH

T-Systems International GmbH serves as the information and communications technology division of Deutsche Telekom AG, headquartered in Frankfurt am Main. While the corporate entity was formally restructured around 2000, its operational roots extend back to the 1995 merger with debis Systemhaus. The company acts as the primary IT arm for the telecommunications group, managing complex digital landscapes for clients ranging from automotive manufacturers like Volkswagen and Daimler to energy firms such as E.ON and BP.

As of 2024, the organization employs roughly 26,000 to 28,000 staff across more than 26 countries, generating annual revenues near EUR 4.2 billion. Ferri Abolhassan currently leads the company as CEO while also serving on the Board of Deutsche Telekom AG. Under this leadership, T-Systems has prioritized sovereign cloud infrastructure and artificial intelligence capabilities, notably establishing a gigafactory for AI in partnership with Microsoft, AWS, Google, and SAP.

The firm navigates a competitive European market by offering integrated end-to-end solutions that emphasize hybrid and multi-cloud architectures compliant with EU regulations. Recent strategic moves include migrating Deutsche Telekom's own SAP environment through the RISE with SAP initiative to reduce complexity. Despite facing significant restructuring pressures that led to announced job cuts of 10,000 positions by 2021, the company secured major public sector contracts for cloud and AI services covering German federal and local authorities in 2026.
