Young team - long tradition

The company at² GmbH is a collaboration of two individual and successful companies: Media provider CoolNetworx, established in 1999 by Dipl.-Kfm. Thomas Otto and 3D developer Blackstar Solutions, established in 2006 by Dipl.-Inf. (FH) André Kettner and Dipl.-Inf. (FH) Tobias Pfob.

Since the establishment of at² GmbH in March 2010, the company’s size steadily increased, employing talented and experienced software developers and designers.
