The Retail Media Fix? dunnhumby Launches Network Alliance to Fight Fragmentation
26 June 2026
By Joe Farely – Head of Strategy
Retail media has a fragmentation problem. Right now, brands chasing scale must juggle a dozen different networks, decipher completely inconsistent metrics, and swallow massive operational headaches just to see if their ads are working.
dunnhumby’s new network alliance wants to fix that.
Announced on June 19, the alliance gives brands and agencies a single, streamlined method to run campaigns across multiple major retailers. Big names like Tesco, B&Q, John Lewis, and Waitrose are already signed up for pilots launching this summer, covering everything from grocery to DIY, with tech firm Kevel handling the build and delivery.
The idea itself is simple enough: instead of forcing brands to manage separate relationships with every single retailer, the alliance sets up a shared framework for activation and reporting. Retailers still hold the keys to their own media businesses, but they get the advantage of standardized infrastructure. Essentially, dunnhumby wants to turn a messy collection of isolated environments into a functioning, connected market. Dunnhumby is uniquely positioned as they has the credentials and experience to act in this way.
Can a Unified Network Solve Retail Media’s Biggest Challenge?
The industry has needed this kind of simplification for a while, the question is whether a network alliance can deliver what individual networks couldn’t. This partnership is in its infancy and a long way off challenging some of the more dominant retail media networks such as Amazon or Criteo.
The real test will be scale. While the pilot focuses on existing inventory, the alliance will need to expand fast to keep up with agency demand. If it can deliver on consistent measurement and ease of use, it will dismantle the two biggest roadblocks holding back brand spend and that’s a commercial bet well worth watching.
