Criteo S.A.

Criteo was founded in Paris, France, in 2005 by Jean-Baptiste Rudelle, Franck Le Ouay and Romain Niccoli. Criteo spent the first four years focused on R&D, and launched its first product in April 2008. In 2010, Criteo opened an office in Silicon Valley. In 2012, Criteo opened its new headquarters in Paris, France.

On April 7, 2011, Criteo announced that it hired Greg Coleman as president. Previously, Coleman served as president and chief revenue officer of The Huffington Post and executive vice president of global sales for Yahoo!.

In October 2013, the firm completed an initial public offering (IPO), raising US$251 million.

On 1 January 2016, Rudelle became the executive chairman, while Eric Eichmann, who was the president and chief operating officer (COO), was promoted to chief executive officer. In June 2016, Criteo alleged Steelhouse, a rival ad tech company, had falsely taken credit for user visits to retailers' web pages in a lawsuit. Steelhouse countersued, alleging Criteo of false advertising and unfair competition. After an injunction requested by Criteo was denied in October 2016, both parties chose to mutually dropped their lawsuits in November 2016. On 4 October 2016, Criteo acquired HookLogic, a retail exchange, ad server and attribution company focused squarely on retailers, strengthening its ecommerce serving capabilities.

In October 2017, Criteo appointed Mollie Spilman as COO.

With the implementation of the Intelligent Tracking Prevention (ITP) feature from Apple 's Safari 11 onwards in September 2017, Criteo's revenue was reduced by $25 million in 2017. However, Criteo reportedly was working on a “sustainable solution for the long-term” at the end of 2017, and had redesigned its "platform architecture" since. Criteo was also impacted by the perception that the General Data Protection Regulation would negatively affect the company.

In April 2018, Rudelle returned as the CEO, with Eichmann being his advisor. Under Rudelle, Criteo slowly transitioned from a single product (web advertising) to a multi-product platform, which included in-app and email advertising. Criteo's revenue did not grow in 2018, and was down 1%.

On 19 October 2019, Megan Clarken was appointed as the new CEO, taking over from Rudelle. Clarken would continue Criteo's transformation plan.

On February 15, 2025, Michael Komasinski took over as CEO and member of the Board, replacing Megan Clarken. Previously, Komasinski was CEO of the Americas, President of Global Data & Technology, and member of the Group Executive Management team at dentsu.

At the end of 2025, it was announced that Criteo would be moving to the United States, via Luxembourg. Les Echos referred to this as an ' exile,' a ' symbol of the French Tech's shortcomings '.
