Criteo has become the first advertising-technology company to integrate with OpenAI's advertising pilot in ChatGPT Free and Go versions in the U.S.

The integration enables brands to make ad buys through Criteo's commerce media platform in OpenAI's AI platform, bringing performance-driven advertising into conversational discovery experiences.

“This integration with OpenAI represents an exciting step forward in advancing advertising in an emerging AI experience,” said Michael Komasinski, CEO  of Criteo.

Through this pilot, Komasinski believes Criteo can help ChatGPT search and discovery in LLMs.

Aggregated insights observed across Criteo's U.S. clients show that users referred from LLM platforms like ChatGPT convert at approximately one-and-a-half times the rate of other referral channels, according to February data from Criteo. 

Criteo activates more than $4 billion in annual media spend and works with 17,000 advertisers globally, connecting brands, retailers, and publishers through commerce intelligence and AI-driven decisioning technology to drive cross-channel outcomes.
