As privacy regulations reshape digital advertising strategies, the StackAdapt Experian partnership aims to help marketers unlock stronger performance by activating first party data with advanced identity resolution and audience intelligence.
StackAdapt announced a strategic collaboration with Experian to enhance data driven advertising capabilities for UK marketers. The partnership enables advertisers to combine their own customer data with Experian’s identity resolution technology and audience segments, including Mosaic profiles, within StackAdapt’s AI powered programmatic platform.
The StackAdapt Experian partnership arrives at a time when brands are adapting to evolving privacy standards, shifting consumer expectations, and reduced reliance on traditional third party identifiers. As marketers increasingly prioritize first party data strategies, the integration provides a privacy conscious pathway to translate customer insights into scalable campaign activation and measurement.
Through the collaboration, advertisers gain access to Experian’s signal agnostic ID resolution system, which covers approximately 80 percent of UK households. This capability allows brands to achieve higher audience match rates across media channels while maintaining compliance with privacy requirements. By layering deterministic data onto advertiser owned datasets, marketers can expand reach without compromising accuracy or relevance.
Brands and agencies using the StackAdapt platform will also benefit from Experian’s extensive third party audience segments, offering demographic, behavioral, and transactional insights. These enriched datasets are designed to support more precise targeting, improved measurement frameworks, and personalized campaign execution across multiple digital channels.
“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.”
The partnership builds on an existing relationship between the companies in North America, where similar integrations have helped advertisers improve data activation and campaign performance. The expansion into the UK market reflects growing demand for interoperable identity solutions that support omnichannel media buying in a privacy first environment.
“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 now available to UK advertisers and agencies, enabling seamless onboarding of first party datasets alongside access to Experian powered audiences. As advertisers seek durable targeting solutions amid ongoing industry change, the StackAdapt Experian partnership underscores the growing importance of identity resolution and data collaboration in delivering measurable return on investment across modern programmatic advertising ecosystems.
