After the completion of his craft training and a diploma (Handelsdiplom) in his pocket Thomas intended to further expand his professional knowledge. After various positions as a product manager in technical agencies, Thomas had the chance to work as a sales manager in the media sector. Instantly he was able to adapt and successfully establish his career. He attended to well-known companies such as Walt Disney, Columbia Tristar (Sony Pictures), Fox Video and MGM and helped to establish those companies in the Swiss market. After a while SEGA was coming along, which was basically his entry ticket into the video-game business. Other stations of Thomas were the setting up of the Swiss office of Electronic Arts. In 2006 he has founded his company Gametime AG.
