Quartile Becomes Technology Partner for ChatGPT Advertising

Retail media optimization platform Quartile announced on September 21, 2026 that it has become a technology partner supporting advertising in ChatGPT, expanding its capabilities into conversational AI-driven product discovery.

The partnership allows participating advertisers to access advertising in ChatGPT through Quartile's existing tools and workflows. According to the company's announcement, ChatGPT has more than 1 billion weekly active users who use the platform to discover products, evaluate options, and make purchasing decisions. Quartile describes the move as an extension of its "experts + AI" approach, which it says combines automation and data with strategic input from experienced advertising professionals.

The announcement noted that ChatGPT Ads feature clearly labeled ads that are visually distinct from ChatGPT responses, and that those responses are not influenced by ads.

Daniel Knijnik, CEO and Co-Founder of Quartile, framed the announcement as part of a broader evolution. "AI is creating entirely new ways for consumers to discover products, but technology alone does not create a successful advertising strategy," Knijnik said. "Our experts + AI approach brings together the scale and speed of AI with the experience and judgment needed to turn those capabilities into meaningful business outcomes. Supporting advertising in ChatGPT is another step in that evolution."

In a second statement, Knijnik addressed the strategic direction: "As advertising continues to evolve, our goal is to help brands understand not just what technology can do, but how to use it intelligently."

Quartile says it supports more than 5,300 brands and sellers worldwide and manages annual advertising spend exceeding $2 billion across major commerce and digital advertising channels. The company said it has received recognition from industry partners including Amazon Ads and Walmart Connect, as well as customer-feedback platforms G2 and Trustpilot.
