Overview
Kelkoo is a European shopping-comparison and ecommerce advertising business that originated in France in 1999. Its core service helps consumers compare products, prices, retailers, and purchasing options across online stores, while giving merchants and publishers a performance-based channel for presenting product offers to shoppers. The business developed during the early expansion of European electronic commerce, when fragmented national retail markets created demand for services that could aggregate product information and make online purchasing easier to evaluate. The company was founded by Pierre Chappaz, Jérôme Mercier, and Mauricio Lopez, with early financing from Banexi Ventures and Innovacom. Its initial expansion relied heavily on consolidation. In 2000, Kelkoo combined with Spanish comparison service Dondecomprar.com and British competitor ShopGenie, followed later that year by a merger with Norway-based Zoomit.com. These transactions brought together businesses with geographic reach and technology in several European markets. Zoomit shareholders received shares representing approximately one-third of the enlarged company, making Zoomit a particularly significant component of the combined organization. Following the mergers, the original businesses were integrated under the Kelkoo identity and the enlarged group was associated with executives and founders including Per Siljubergsåsen, William Klippgen, Philip Wilkinson, and Jorge Garcia. Kelkoo expanded beyond a direct consumer website through partnerships and distribution arrangements. In 2003 it partnered with the European arm of Microsoft's MSN to provide shopping listings. In 2004 it announced a similar relationship with Ask.com, then known as Ask Jeeves. The company also developed partner-site and affiliate arrangements, allowing external websites and browser-oriented shopping tools to use data from its product database. Under this model, partner services could generate qualified shopping clicks and share in the resulting revenue. Search-engine optimization, partner distribution, merchant listings, and advertising relationships were central elements of its customer-acquisition and monetization strategy. Yahoo acquired Kelkoo on 26 March 2004 for €450 million. Yahoo presented the transaction as a way to improve advertisers' ability to target individual products and to strengthen its commercial-search capabilities. Kelkoo subsequently operated within Yahoo's broader internet portfolio until Yahoo sold it in November 2008 to Jamplant Ltd, a British private equity firm. Richard Stables became chief executive of Kelkoo Group in 2009. The business continued to develop its international footprint. It launched a Brazilian site in 2012 after choosing Brazil as an expansion market over India and China. By the time described in the group's reference history, Kelkoo operated across 22 countries, with offices in London, Paris, Grenoble, Vilnius, Oslo, and Milan. Its activities combined comparison shopping, product-feed distribution, ecommerce advertising, affiliate services, and application programming interfaces for partners that wanted to incorporate shopping data into their own products. A major later turning point came in October 2016, when Kelkoo acquired LeGuide group, a French price-comparison company described in the reference material as a market leader in France. The combination brought together two established European comparison businesses and led to the use of the Kelkoo Group branding. The enlarged organization presented itself as a leading European shopping-comparison platform with a broader merchant network, consumer audience, and geographic reach. Kelkoo's current operating identity is therefore the result of successive mergers, ownership changes, international expansion, and the integration of LeGuide rather than solely the original French startup.
History
Kelkoo was established in France in 1999 by Pierre Chappaz, Jérôme Mercier, and Mauricio Lopez. Banexi Ventures and Innovacom provided approximately $3 million in initial funding. The company entered a market in which consumers were beginning to purchase online but still faced difficulty comparing offers across separate national retail websites. Kelkoo's concept was to aggregate merchant product information and present comparable listings, helping shoppers evaluate prices and directing them to participating retailers. The company pursued rapid European expansion through mergers. In April 2000 it combined with Dondecomprar.com, a Spanish service, and ShopGenie, a United Kingdom competitor. In September 2000 it merged with Zoomit.com, a Norwegian comparison service. The Zoomit transaction was conducted through the issuance of Kelkoo shares to Zoomit's shareholders, who received roughly one-third of the enlarged company's equity. These combinations created a broader European operation and brought together the founders and management of several previously independent comparison businesses. Kelkoo's commercial model included direct consumer traffic, search-engine optimization, merchant listings, advertising, affiliate referrals, and data distribution. It also supplied shopping information through an API web service, enabling other comparison websites and shopping tools to use product data from its database. External partners could earn commissions from qualified clicks generated through their services. The company reported profitability from the fourth quarter of 2002, according to the reference history. Distribution partnerships helped Kelkoo reach users beyond its own websites. In June 2003 it partnered with Microsoft's European MSN operation to provide shopping listings. In June 2004 it announced a comparable arrangement with Ask.com, then operating under the Ask Jeeves name. These agreements reflected the growing importance of integrating product discovery into major web portals and search destinations. Yahoo acquired Kelkoo on 26 March 2004 for €450 million. Yahoo said the acquisition would help advertisers target individual products more effectively. Kelkoo therefore became part of a larger internet company at a time when shopping search, product feeds, and online advertising were converging. In November 2008 Yahoo sold Kelkoo to Jamplant Ltd, a British private equity firm. Richard Stables became chief executive officer in 2009. After the ownership transition, Kelkoo maintained its European orientation while extending its geographic presence. The company launched a Brazilian website in 2012. Its stated operating footprint later covered 22 countries in Europe, North America, and Latin America, supported by offices in London, Paris, Grenoble, Vilnius, Oslo, and Milan. The business served consumers directly while also operating as an infrastructure and traffic source for merchants, publishers, affiliate sites, and other shopping applications. In October 2016 Kelkoo acquired LeGuide Group, a major French price-comparison business. The transaction joined two established players and prompted the group to update its branding to Kelkoo Group. The combined company described the deal as creating a leading European shopping-comparison position, with expanded market coverage and a larger network of merchant and publisher relationships. Kelkoo Group's development thus reflects a sequence of startup formation, cross-border consolidation, portal partnerships, acquisition by Yahoo, private-equity ownership, international expansion, and renewed scale through the LeGuide transaction.
