Overview
Criteo is a French advertising technology company founded in Paris in 2005 by Jean-Baptiste Rudelle, Franck Le Ouay, and Romain Niccoli. It became widely known for performance advertising and retargeting: displaying personalized banner and other digital advertisements to people who had previously interacted with an advertiser or retailer. Its commercial model historically emphasized measurable outcomes, commonly using cost-per-click pricing and machine-learning systems to select audiences, bids, creative formats, and placements. The company spent its first several years on research and development before launching its first product in 2008. It expanded internationally, opening a Silicon Valley office in 2010 and establishing a new Paris headquarters in 2012. A self-service cost-per-click bidding platform introduced in 2010 gave advertisers greater control over campaign bids and performance optimization. Criteo subsequently expanded beyond conventional web retargeting into mobile applications, email, audience discovery, traffic generation, and retail media. Criteo's strategic development has increasingly centered on commerce media: advertising and measurement services connected to retailers, commerce platforms, brands, agencies, and publishers. Its offerings use purchase-intent and other behavioral signals to help advertisers find prospective customers, encourage transactions, and measure outcomes. Retailers can also use Criteo technology to sell advertising inventory on their own digital properties and to provide sponsored placements to consumer brands. This broadened model was reinforced by the 2016 acquisition of HookLogic, a retail exchange, ad server, and attribution business. The company became publicly traded through an initial public offering in October 2013, which raised approximately US$251 million according to the cited reference material. Its expansion has also been shaped by changes in the digital advertising environment. Apple's Intelligent Tracking Prevention on Safari reduced Criteo's reported revenue by approximately US$25 million in 2017, while privacy regulation and the European Union's General Data Protection Regulation created additional compliance and measurement challenges. Criteo has faced continuing scrutiny over consent, tracking, and the use of online behavioral data. The company has stated that it does not depend on personally identifiable information, does not share such information with advertisers or publishers, and uses anonymous information supplied through merchant interactions. In June 2023, France's data-protection authority, the CNIL, imposed a €40 million sanction relating to consent and data-processing obligations. The episode illustrates the tension between Criteo's performance-marketing model and increasingly restrictive privacy expectations. Leadership has changed several times as Criteo moved from a focused retargeting product toward a broader platform. Jean-Baptiste Rudelle served as chief executive at different stages and became executive chairman in 2016 before returning as CEO in 2018. Eric Eichmann, previously president and COO, succeeded him as CEO in 2016 and later became an adviser. Megan Clarken became CEO in 2019 and continued the company's multi-product transformation. Michael Komasinski became CEO and a board member on February 15, 2025, succeeding Clarken. Criteo remains an active, publicly listed international ad-tech company whose positioning combines commerce data, machine learning, measurable advertising outcomes, and retail-media infrastructure.
History
Criteo was established in Paris in 2005 by Jean-Baptiste Rudelle, Franck Le Ouay, and Romain Niccoli. The founders initially concentrated on research and development, delaying the commercial launch of the company's first product until April 2008. The early business focused on performance advertising, particularly retargeting: serving display advertisements to users whose earlier activity indicated an interest in a retailer or product. International expansion began with the opening of a Silicon Valley office in 2010. In September of that year, Criteo introduced a self-service cost-per-click bidding platform that allowed advertisers to manage campaign bids and monitor performance in near real time. The company also began a public-facing effort to explain retargeting and address consumer privacy concerns. Criteo said its approach used anonymous information derived from merchant interactions rather than personally identifiable information, and that such information was not shared with advertisers or publishers. Criteo opened a new Paris headquarters in 2012 and went public in October 2013. The IPO raised approximately US$251 million. As the business matured, its leadership structure evolved. Greg Coleman was appointed president in 2011. On January 1, 2016, Rudelle became executive chairman and Eric Eichmann, previously president and chief operating officer, became CEO. Later that year Criteo acquired HookLogic, a retail exchange, ad server, and attribution company. The transaction strengthened Criteo's relationships with retailers and helped move the business beyond a single retargeting product. The company encountered significant changes in the technology and regulatory environment in the late 2010s. Apple's Intelligent Tracking Prevention, introduced in Safari 11 in 2017, restricted forms of cross-site tracking and was reported to have reduced Criteo's revenue by about US$25 million that year. The prospect and subsequent implementation of the European Union's General Data Protection Regulation also increased concern about consent, data collection, and advertising measurement. In October 2017, Mollie Spilman was appointed COO. In April 2018, Rudelle returned as CEO while Eichmann became an adviser. During this period Criteo began moving from a primarily web-advertising business toward a multi-product platform incorporating in-app and email advertising. Revenue nevertheless declined slightly in 2018. Megan Clarken became CEO on October 19, 2019, and continued the transformation toward a broader commerce and marketing technology platform. During 2020, Criteo introduced a traffic-generation product based on purchase-intent data and a self-service advertising platform for its retail-media division. These developments reflected the growing importance of retailers' owned digital properties as advertising environments. Criteo's broader strategy combined audience discovery, performance optimization, retail-media monetization, and attribution. Privacy remained a major issue. Privacy International filed a complaint against Criteo in 2019, and complaints were also associated with the European privacy advocacy organization NOYB. In June 2023, France's National Commission on Informatics and Liberty, known as the CNIL, imposed a €40 million sanction, citing shortcomings connected with consent and data processing. The case became one of the most consequential regulatory events in Criteo's history. On February 15, 2025, Michael Komasinski became CEO and joined the board, replacing Megan Clarken. Before taking the role, he had served as CEO of the Americas and president of Global Data & Technology at dentsu. Criteo's historical trajectory is therefore defined by a shift from a specialized retargeting company to a broader commerce-media provider, alongside continuing adaptation to browser restrictions, privacy law, retailer demand, and changes in digital advertising measurement.
