StackAdapt Partners With Experian to Supercharge First-party Data Activation for Advertisers

StackAdapt, the leading AI advertising and orchestration platform, has announced a strategic partnership with global data and technology company, Experian. This partnership empowers UK marketers to maximise the value of their first-party data, leveraging Experian’s advanced ID Resolution and audiences, including industry-leading Mosaic segments, across StackAdapt, one of the fast-growing AI advertising platforms worldwide. Through this collaboration, advertisers can unlock higher match rates into media channels and richer audience insights, powering more impactful, scalable campaigns that reach the right audiences and deliver stronger return on investment.

Amid evolving privacy regulations, consumer expectations and platform adaptations, the ability for marketers to harness first-party data alongside high-quality third-party datasets has become a core driver of performance. Integrating Experian’s signal-agnostic ID resolution—with 80% coverage of UK households—provides advertisers within the platform with a direct, privacy-aware route to translate their customer knowledge into precision targeting and measurement, layering Experian’s extensive deterministic data to expand reach without sacrificing relevance or privacy.

This announcement extends a successful relationship between StackAdapt and Experian in North America, now bringing the benefits of this integration to the UK market.
