Curriculum Vitae
Ralph Dommermuth
In 1988, Ralph Dommermuth founded 1&1 Marketing GmbH, the company that was to grow into what is today United Internet AG. His initial business was the provision of systematised marketing services to small software providers. He later developed additional marketing services for large customers such as IBM, Compaq and Deutsche Telekom. As the internet became increasingly professional, the scope of these marketing services for third parties was successively reduced and the focus was shifted to the company's own internet services. In 1998, the trained banker managed the IPO of 1&1, which was the first internet company on the Frankfurt stock exchange. Ralph Dommermuth restructured 1&1 in 2000 and it became United Internet AG. United Internet operates today in two divisions. In the segment Applications, United Internet is internationally one of the leading providers with business activities in European countries (Germany, France, Great Britain, Italy, the Netherlands, Austria, Poland, Switzerland, Spain) and in North America (Canada, Mexico, USA). Products include domains, home pages, web hosting, servers and applications for personal information management and online applications. The landline and mobile network products for private users at Drillisch/1&1 Telecommunication and the data and network solutions for 1&1 Versatel business customers are bundled in the segment Access. As of 1 January 2018, Ralph Dommermuth is CEO of Drillisch AG as well as CEO of United Internet.
