Powered by Bernd's strategic sales strength, the two companies developed into leading suppliers of office applications and vertical software solutions in the German-speaking market; and provided a solid foundation for O3SIS which was formed in 1996 by merging Regie and Quadratron. Bernd served as O3SIS CEO from 1996, leading the company into the mobile and wireless market space, developing innovative business models, and negotiating several high-profile deals with first tier European mobile network operators.
