StackAdapt, the leading AI advertising and orchestration platform, has formed a strategic partnership with Experian, a global data and technology company. The collaboration empowers UK-based advertisers and agencies to maximize the value of their first-party data by leveraging Experian’s advanced ID resolution and high-quality audience segments—including industry-leading Mosaic—for more precise, scalable, and privacy-compliant campaigns on StackAdapt.
With increasing privacy regulations, shifting consumer expectations, and platform adaptations, marketers face growing challenges in activating first-party data effectively. This partnership addresses these issues by providing a direct, privacy-aware path to translate customer knowledge into actionable targeting and measurement.
Experian’s ID resolution technology—covering 80% of UK households—delivers high match rates, enabling advertisers to connect their first-party data to media channels with greater accuracy. Combined with Experian’s extensive deterministic datasets and Mosaic segments, brands can enrich audiences with deep demographic, behavioural, and transactional insights, fueling more personalized and impactful campaigns.
“This marks a major milestone for our UK growth strategy,” said Michael Shang, SVP, Advertising Technologies at StackAdapt. “Combining Experian’s unmatched consumer data footprint with StackAdapt’s programmatic capabilities gives our clients a powerful advantage in reaching and engaging their most valuable audiences with precision and accountability.”
“Experian’s relationship with StackAdapt in the US and Canada has been instrumental in enabling marketers in North America to unlock the full potential of their first-party data, and we’re excited to bring that momentum to the UK,” said Colin Grieves, Managing Director, Experian Marketing Services, UK&I. “By combining our powerful audience database—which reaches the vast majority of UK households—with StackAdapt’s innovative platform, we’re enabling advertisers to harness both first-party and third-party data to deliver smarter, more personalised campaigns at scale.”
The integration is live for UK-based advertisers and agencies on StackAdapt. Clients can onboard first-party data seamlessly, access Experian-powered audiences, and activate more efficient media campaigns across programmatic channels.
This extension strengthens StackAdapt’s position as a unified AI advertising platform, helping brands and agencies achieve stronger ROI through data-driven, privacy-compliant strategies.
