Kelkoo Group

What Kelkoo Group does

Kelkoo Group is a privately-held European performance marketing platform, founded in 1999 and headquartered in Paris (with a UK & Europe headquarters in London), that connects retail advertisers with high-intent shoppers across 29 global markets. The company operates a two-sided platform serving two primary customer segments: retail advertisers (merchants) seeking to reach purchase-ready shoppers via CPC-based performance marketing, and publishers (website owners, comparison sites, aggregators) looking to monetize their traffic through shopping integrations. Its advertiser-side offering is anchored by Performance Flex, an ML-powered dynamic CPC pricing engine that prices every click based on predicted conversion potential to maximize ROAS, and Advance (Core and Max), a Premium Google CSS Partner solution for managing Google and Bing Shopping campaigns with optional bespoke AI feed optimization. Its publisher-side offering comprises three integration options — Links, Search API, and Feeds API — providing flexible monetization routes for editorial, comparison, and aggregator sites.

The company monetizes through usage-based CPC pricing on advertiser spend flowing through its owned comparison shopping network (Kelkoo, LeGuide, Ciao), Google Shopping via CSS partnership, Bing Shopping via Microsoft Ads partnership, and the broader partner shopping network. Kelkoo reports 6bn+ high-intent clicks annually, 10,000+ advertisers, and €500m+ in advertiser sales generated per year; it claims a 93% ROAS-target achievement rate and a 94% client retention rate. The go-to-market is sales-led for enterprise advertisers, supplemented by self-service publisher onboarding. The technology stack is built on proprietary ML optimization developed over more than a decade, supported by an engineering center in Grenoble and approximately 160 employees across France, the UK, Italy, Germany, and Spain.
