Founder and owner of PharmaSGP GmbH

In 2009, Clemens Fischer – a Harvard University MBA graduate who also holds a doctorate in medicine and a Business Economics degree – jointly founded PharmaSGP with Madlena Hohlefelder. Today, PharmaSGP is one of the leading OTC pharmaceutical companies in Europe and, in fact, the fastest growing company in the OTC market; in 2015, the company was awarded “Best OTC Company of the Year.” At the moment, Clemens Fischer is primarily focusing on the expansion of the company’s international presence – even beyond the European market into Asia and the US.

At age 17, Clemens Fischer discovered his passion for entrepreneurship after founding his own mobile phone company. Ever since, the serial entrepreneur has founded numerous companies, many of which he sold after successfully positioning them in the market; amongst the buyers are pharmaceutical giants such as Novartis, Dermapharm, and Perrigo. Most recently, the businessman sold his diet product Yokebe, the second biggest diet product in the German market, to Omega, a Perrigo subsidiary. The deal was closed in the three-digit million Euro range and was his seventh deal in a row. Before establishing his own pharmaceutical company, Clemens Fischer worked for companies such as Novartis, where he was a member of the German executive board and was responsible for the Strategy and Cardiovascular divisions.
