The story

Strato was founded by Marc-Alexander Ulrich, former member of the board of Escom, and Norbert Stangl, former managing director of 1&1 Internet. Since 1997, Strato offers a broad variety of webhosting plans for private and business customers in Germany. Beginning in 2006, Strato expanded operations to Italy, France, Netherlands and Poland as well as the United Kingdom. In 2010, Strato launched a cloud storage platform called HiDrive, which became free of charge for entry packages in September 2011. With its e-commerce offering, Strato relies on Shopping cart from ePages. The DSL segment, offered by Strato between 2007 and 2009, was sold to United Internet AG in 2009. Deutsche Telekom acquired Strato in November 2009 in order to expand the hosting business of T-Online. Deutsche Telekom sold Strato to United Internet for around 600 million Euro in December 2016.
