With a 15+ year track record in managing technology-driven companies which focus on consumer centric services, Holder was with gate5 from the early days – a company which specialised in mobile navigation and was acquired by Nokia in 2006. This company was the foundation of HERE maps, which was taken over by three German car makers in 2015 for almost 3 billion Euros. In 2008, he was one of the first investors of Aupeo, today’s leading content platform for automotives. Since 2010, Holger led the company as CEO. In April 2013, Aupeo was acquired by Panasonic Automotive Systems. Holger continued to manage the integration and alignment after the acquisition. At the end of 2015, he stepped down as CEO to focus on new entrepreneurial challenges. He is also an active business angel and startup mentor and is involved with companies in Germany, UK and the US. As a specialist for connected mobility he also acts as a board member, conference speaker and author.
