Founded in 1998 and based in Montabaur, Germany, the operating business of United Internet AG is divided into the two business divisions “Access” and “Applications”, which in turn are divided into the segments “Consumer Access” and “Business Access”, as well as “Consumer Applications” and “Business Applications”.

United Internet provides consumers and business clients with landline and mobile internet access products, as well as various cloud applications which operate at our 10 data centers. The use of these services is based on subscription contracts with fixed monthly fees as well as variable, volume-based charges.

Target group-specific marketing via well-known brands

Our access products targeting specific customer groups are marketed in the Consumer Access segment via our premium brand 1&1 and discount brands, such as yourfone and smartmobil.de. Business Access products are offered by 1&1 Versatel.

Our Consumer Applications are marketed via the differently positioned brands GMX, mail.com and WEB.DE. And Business Applications via IONOS as well as STRATO, Arsys, Fasthosts, home.pl, InterNetX, united-domains and World4You. In addition, the Sedo brand offers customers around the world professional services in the field of active domain management, while we22 offers other hosting suppliers a white-label website builder for the creation of high-quality websites.

International Footprint

Whereas we operate exclusively in Germany in the Access division, we are also a leading global player in the Business Applications segment.

We target the major European economies of Germany, France, the UK, Italy, the Netherlands, Austria, Poland, Switzerland, and Spain, as well as the North American countries Canada, Mexico, and the USA.
