The two Hungarian subsidiaries of the Atos Group, which employs nearly 110,000 employees across 71 countries, will be relocating their headquarters to the Kalvin Square Office Building starting from the spring of 2024. The crucial moment in this multi-stage selection process occurred at the end of August when contracts were signed. Atos Hungary and Eviden Hungary Kft. will share a 760-square-meter office space on the seventh floor of the Kalvin Square Office Building, offering a panoramic view of Gellért Hill.

ConvergenCE prioritizes social sustainability, with a particular focus on accessibility. Their office buildings: CityZen, ZenGarden and Kálvin Square, obtained Access4you certification in 2020, being among the first to do so.

A rapidly growing SaaS company is moving into the Kálvin Square Office Building, which was recognised with a BREEAM Excellent rating in September. Headquartered in Singapore, Trax has established branches in many parts of the world, with offices in Denver Colorado, Paris, Tel Aviv, and Budapest. Employing more than 600 people, the tech company's employees are at the heart of its existence, and the Hungarian managers of Trax, founded in 2010, have sought and found the right environment for its outstanding team at Kálvin Square Office Building.
