PubMatic partners with GroupM to deliver AI generated cohort

PubMatic (PUBM) announced a partnership with GroupM, WPP‘s (WPP) media investment group, to deliver cohort-based modeling capabilities for advertisers. This collaboration, a first-of-its-kind in the market, leverages a distributed AI model via Resolve, a Choreograph company, to enable scaled targeting across multiple publishers simultaneously, ensuring privacy-first ad buying at scale. The proprietary technology utilizes impression level data to generate privacy-compliant audience segments. The technology delivers sustainable scalability for both buyers and sellers, with no personal data moved or shared in the buying process. Data is exclusively connected to inventory on the sell-side, creating enhanced auction packages for advertisers through advanced demand-side tools.
