LONDON, 3 December 2025 - Ocado Ads has partnered with Epsilon, a leader in technology, data and services, to develop a retail media solution powered by COREid — Epsilon’s industry-leading identity resolution platform. This people-based approach allows brands to connect with real individuals, not proxies, across a wide range of offsite environments, including TV.
It marks a major step forward in Ocado Ads’ vision to build a media platform grounded in precision, performance and advertiser control. With COREid integrated, the groundwork is laid for brands to connect offsite activity through a unified attribution framework that links exposure to outcomes across channels, establishing a single, connected view of performance.
“This partnership reinforces our commitment to putting real control in the hands of advertisers,” said Ben O’Mahoney, AdTech & Data Partnerships Lead from Ocado Ads. “By bringing digital media, data and retail execution together, we’re making it easier for more brands to participate—and more likely for shoppers to connect with the brands that matter to them.”
Ocado’s retail media proposition is underpinned by a unique operating model, a foundation that has helped make it Britain’s fastest-growing retailer for over a year (Kantar). Operating exclusively online, Ocado offers one of the richest, most complete grocery data sets in market with no requirement for loyalty card data.
Collaborating with the Epsilon Retail Media platform further leverages the data by enabling brands to extend their reach beyond Ocado’s properties, seamlessly activating across the open web, connected TV and audio. Whether it’s Netflix, Disney+ or Spotify, brands can connect with verified audiences wherever they are, while maintaining consistent, personalised messaging.
Epsilon’s COREid brings stability and accuracy to activation. With closed-loop measurement and actionable insight built in, advertisers can now tie investment directly to sales performance, supporting incrementality, faster optimisation, and greater accountability across campaigns.
“The focus is on enhancing the entire shopping experience and driving incremental value for brands and shoppers, delivering on the full promise of retail media”, commented Tim Frankcom, President of Europe and APAC, Epsilon. “Together, we’re giving brands a single, powerful route to real, verified shoppers across every screen. It’s retail media without any guesswork.”
