Sedo (an acronym for Search Engine for Domain Offers and stylised sedo) is a domain name and website marketplace and domain parking provider based in Cambridge, Massachusetts and Cologne, Germany. The company, which is a subsidiary of German-based United Internet, has more than 16 million domain names listed on its website for buying and selling.[2]



Sedo was founded in 2000 by three German college students - Tim Schumacher (previous CEO of Sedo Holding AG), Marius Würzner (now COO of Sedo GmbH's German office), and Ulrich Priesner (currently CTO of Sedo) - and modeled after the core concept of Schumacher's Master's Thesis, "Price Formation in the Trade of Internet Domain Names". In February 2001, with 1&1 Internet AG's investment in the business through purchasing a 41% share, Sedo GmbH became an official entity in Cologne, Germany.[3] During the first few months, the company was operated solely by Schumacher and Essmann while Priesner and Würzner finished their studies. Helga Schackenberg became the first employee of the company, followed soon thereafter by Würzner. At the end of the year, Essmann left the company for nearly two years to complete his medical residency. In the meantime, Sedo moved into a bigger office in Cologne in 2002, and Matt Bentley joined the company to serve in Essmann's absence to oversee Sedo's development. Sedo's funding prior to IPO was N.M. Rothschild Holdings .

Sedo began planning in 2003 to open a subsidiary office in the United States. During this planning phase, Essmann returned to the company with a desire to lead overseas. Bentley and Essmann headed to America, with Jeremiah Johnston joining the team shortly afterwards as General Counsel. In 2005, the Sedo office was opened in Cambridge, Massachusetts (USA), under, LLC.[4]

In 2006, CEO Tim Schumacher temporarily joined the Cambridge office to assist with expansion into the US market, and the company introduced domain name auctions.[5] In 2007, Sedo took a minority investment in DomainsBot;[6] DomainsBot's technology later contributed to the update of Sedo's domain search tool. The company acquired, a competing online domain name marketplace, from VeriSign on June 19, 2007.[7][8]

Expansion continued in 2008 as Sedo opened up shop in the United Kingdom, an operation headed by Hugo Dalrymple-Smith and Nora Nanayakkara. On February 24, 2009, Sedo purchased RevenueDirect, and formed a strategic partnership with its parent company, Dotster of Vancouver, Washington, to take advantage of the latter's services of helping businesses establish online profiles.[9] In March 2009, Sedo provided seed funding for the new start up, a social charity website.[10] Later in September 2009, Sedo acquired a competing domain monetization (parking) site, ParkingPanel, for an undisclosed amount.[11] On February 17, 2010, Sedo helped broker the purchase for the most expensive .org domain name ever——for US$1 million. purchased the domain name.[12] Later that year, Sedo was awarded a Guinness World Records record for the sale of, the most expensive public domain sale at $13,000,000.[13]

On February 1, 2012, Tim Schumacher left his role as CEO of Sedo Holding AG to focus on other projects and join the company's Supervisory Board. Tobias Flaitz, formerly of the privately held German-based Hubert Burda Media, joined Sedo as the new CEO of both Sedo Holding AG (including Sedo's sister company, and Sedo.[14]

Sedo Holding AG[edit]

In 2009, Sedo's sister company within the Adlink Group, AdLINK Media, was sold to the Hi-media Group.[15] This sale led to the reorganization and renaming of the group to Sedo Holding AG in 2010. That same year, Sedo welcomed its sister company, Affilinet, to its Cologne office. Tim Schumacher was named CEO of Sedo Holding AG while retaining his leadership role within Sedo, and Liesbeth Mack-de Boer was named Chief Sales Officer (CSO) of Sedo.
