Cristoph Ostermann

Co-Founder & CEO

Christoph Ostermann is Co-Founder and CEO of sonnen, Europe’s market leader for residential energy storage systems. In 2008, when even in Germany the market for storage systems was still non-existent, he and his co-founder Torsten Stiefenhofer decided to join forces and to use their complementary skills to turn their vision into reality. Since the launch of the first prototype in 2010, Christoph is now on the mission to create a global one stop shop for decentralized energy and to disrupt the energy market. Christoph is a serial entrepreneur and started his first venture at the age of 18. Before launching sonnen, he had already built and developed four companies. In addition, Christoph spent five years in consulting, focussing on marketing and sales. He holds a degree in Business Administration.
