The visionaries

Florian Buzin studied Computer Science at the University of Karlsruhe, and during his studies he already worked at ASTARTE NEW MEDIA AG as the key developer of the successful web content management system webEdition. In 2003 he founded Easywe GmbH, which has developed business applications for companies like DaimlerChrysler and insurance company Cardif Versicherungen, among other things.

Barbara Mauve worked as a graduate industrial designer at ASTARTE NEW MEDIA AG in a managerial position in the field of concept and design for software solutions and Internet applications. As a freelance designer, she then assisted customers like Böhringer Ingelheim, DaimlerChrysler and DKFZ with the design of complex software and Internet solutions.

Jürgen Signer was initially Managing Director of Aastra Germany and subsequently became Managing Director of Mitel in Germany. Before his move to Aastra, he was in an executive position at Siemens Enterprise Communications (today: Unify) for many years, culminating in being responsible for all sales in Germany as Senior Vice President and Member of the Executive Board.

Our Team

We are a dynamically growing technology company, and our headquarters are in the city center of Karlsruhe in Germany. At STARFACE, we all work together as one team. We stick together, help each other out and regularly exchange ideas and information. We keep hierarchies flat so that as little time as possible is wasted and so that we can concentrate better on our projects. We enjoy our work – and that rubs off.
