The Management Board of United Internet AG consists of Ralph Dommermuth and Martin Mildner.
CEO since 1988
Ralph Dommermuth laid the foundation for today’s United Internet AG with the formation in 1988 of 1&1 Marketing GmbH. He originally offered systemized marketing services for smaller software suppliers. He later developed additional marketing services for major clients, such as IBM, Compaq and Deutsche Telekom. With the growing professionalization of the internet, these marketing services for third parties were gradually reduced and the company offered its own internet services. In 1998 the qualified banker took 1&1 to the stock exchange. It was the first IPO of an internet company in Germany. In 2000, Dommermuth restructured 1&1 as United Internet AG.
