The website Kelkoo is a European price comparison service founded in France in 1999, allowing customers to find information on products they want to purchase, including price and seller information. It was bought by Yahoo! in 2004. It operates in 10 countries, including UK, France, Spain, Italy, Norway, Sweden, Germany, Denmark, Netherlands, and Belgium. On 21 November 2008, Yahoo! sold Kelkoo to Jamplant, a private equity company.
Kelkoo was founded in 1999 by Pierre Chappaz and Mauricio Lopez. Initial funding of $3 million was provided by Banexis Ventures and Innovacom. Once Kelkoo merged with 3 other European businesses, it absorbed those founders into one single collective, consisting of Per Siljubergsåsen, William Klippgen, Philip Wilkinson, and Jorge Garcia
In April 2000, within days of each other, Kelkoo merged with Spanish-based Dondecomprar.com and UK-based competitor ShopGenie. In September of the same year, Kelkoo merged with Norway-based Zoomit.com, paying the Zoomit-shareholders in shares amounting to a third of Kelkoo's total equity making Zoomit.com the largest entity within "new" Kelkoo.
In October 2005 a book on Kelkoo appeared in French called Ils ont réussi leur start-up! La success-story de Kelkoo. written by Julien Codorniou and Cyrille de Lasteyrie.
Origin of the name
Kelkoo has been profitable since Q4 2002. Similar to other price comparison services in how it operates, Kelkoo has focused much of its marketing on capturing users through SEO and launching partner sites including ITV's PriceTerrier.com.
In addition to being a price comparison site, Kelkoo also offers an API webservice where other price comparison websites, such as PriceSpin.com shopping comparison website, and SmartShopper.com price comparison browser add-on, use data and content from Kelkoo's database. This is a shared revenue business model. Kelkoo offers an affiliate commission to the partner sites who use their data for every qualified click that they generate.
Kelkoo historically was a Europe-based price comparison service. With the rapid e-commerce growth of the BRIC countries, Kelkoo launched their Brazil website in 2012. Winning over India and China, Brazil has a large growing market with a sizable population who have purchased online previously. Since the launch, the Brazil business has shown growth and potential.
