Sedo, which stands for Search Engine for Domain Offers, is a domain name marketplace and domain parking provider. Sedo was founded in Germany in 1999, and has headquarters in both Cambridge, Massachusetts and Cologne, Germany. The company has 150 employees from more than 25 countries at offices located in the United States, Great Britain, and Germany, and 1 million customers with 16 million domain names.[1]

Sedo is a subsidiary company of the Sedo Holding AG under the German company United Internet AG. The company is registered in the United States as LLC.[2]


  • Sedo was founded in Cologne, Germany in 1999 as a student project by Tim Schumacher, Ulrich Priesner, and Marius Würzner. They had a website names to distribute computer games, and when the business was phased out, they started thinking about selling the domain. Thus, they founded for Sedo. The company started out with 5 employees working in a small office in downtown Cologne. [3]
  • In his book International Entrepreneurship: Starting, Developing, and Managing a Global Venture, Robert D. Hisrich described that at the beginning of 2000, the founders of Sedo began to advertise by purchasing banners in various websites and developing press relationships. Ulrich Essmann, a medical student working on a project similar to Sedo, joined the team and his own project helped the group significantly. Finally, the founders began negotiating with potential investors. In 2001, they found a major investor, United AG, which at the time was Germany's largest register for domain names. United AG initially purchased a minor stake in the newly-founded Sedo but later bought about 41% for approximately 400,000 EUR. The rest of the shares were held by the four owners. In 2004, United bought additional 10% of Sedo's share for $575,000; thus, making the four founders minority shareholders of the business. In 2005, 51% of shares for United AG, including Sedo, were sold to AdLink Internet Media AG, a public and majority owned subsidary for United Internet AG.
  • In February, 2009, Sedo acquired RevenueDirect, a domain name parking service by run Dotster.[6] Sedo also announced a strategic long-term partnership with Dotster through which Sedo would benefit from Dotster's inventory and registrar service, and RevenueDirect customers would be helped by Sedo’s monetization engines and its secondary market for buying and selling domain names.[7]
  • In March, 2009, Sedo invested seed funding for, a new social charity website.[8]
  • In February 2010, Sedo sold the domain name for US$1 million to, breaking the record for the highest .org domain name ever sold.[9]
