StackAdapt and Experian expand UK tie-up

StackAdapt has entered a strategic partnership with Experian to strengthen its data capabilities in the UK, enabling marketers to activate first-party data with enhanced identity resolution and audience insights.

The agreement gives UK advertisers access to Experian’s ID resolution technology and audience segments, including Mosaic, within the StackAdapt platform. The companies state that the integration will improve match rates across media channels and provide deeper audience insights to support campaign performance and return on investment.

Privacy-aware ID resolution for UK marketers

As privacy regulations and platform requirements evolve, brands are placing greater emphasis on activating first-party data alongside verified third-party datasets. Through the partnership, StackAdapt integrates Experian’s signal-agnostic ID resolution, which covers 80 percent of UK households, offering advertisers a privacy-aware way to translate customer data into targeted media activation and measurement.

The integration also enables advertisers to layer deterministic data from Experian to extend campaign reach while maintaining relevance and compliance.

Michael Shang, SVP, Advertising Technologies, StackAdapt: "This marks a major milestone for our UK growth strategy. 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."

Extending North American collaboration to the UK

The partnership builds on an existing relationship between StackAdapt and Experian in North America and now brings the combined offering to the UK market.

Brands and agencies using StackAdapt in the UK will gain access to Experian’s third-party audience segments, covering demographic, behavioural and transactional data. The companies say this will support improved measurement, audience enrichment and multi-channel campaign delivery.

Colin Grieves, Managing Director, Experian Marketing Services, UK&I: "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. 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 available immediately to UK-based advertisers and agencies.
