About
Criteo is a Paris and New York-based commerce media company publicly traded on Nasdaq under the ticker CRTO that evolved from a retargeting advertising pioneer into a broad commerce media platform connecting retail media networks, brands, and publishers across the open internet. Founded in 2005, Criteo's original product — dynamic retargeting that served personalized product ads to shoppers who had visited a retailer's website — established the company as a leader in performance advertising for e-commerce and drove its 2013 Nasdaq IPO. The company subsequently transformed its platform in response to the deprecation of third-party cookies and the rise of retail media, positioning Criteo's first-party data graph and retailer partnerships as the foundation for a privacy-compliant, commerce-intent-driven advertising ecosystem that addresses post-cookie advertising performance challenges.
