Unlimitail will sell the advertising inventory of Coopérative U's online store, CoursesU.com, and its apps.
By adding this new player to its retail media network of 40 partners, Unlimitail creates a single point of entry to nearly 35% of the French grocery market for brands and agencies: one team, one technology and one measurement standard for advertisers.
Paris, October 2026 - Coopérative U and Unlimitail today announce a multi-year retail media partnership, which will begin in January 2027 with the sale of the Cooperative's digital inventory in France.
2026 will have been a turning point for retail media, with investment surpassing that of linear television worldwide for the first time. By drawing on Unlimitail, Coopérative U is accelerating its retail media strategy and will benefit from the expertise of France's leading grocery retail media player, whose network will represent nearly 35% of the grocery market and nearly 50% of e-commerce retail media investment.
Coopérative U, a fast-growing retailer that complements the Unlimitail network
Coopérative U is a cooperative of independent retailers comprising more than 2,000 stores. The fourth-largest French grocery retailer, it posts one of the sector's most dynamic growth rates and, through its CAP 15 plan, has set itself a target of 15% market share by 2030.
CoursesU.com reaches a family customer base that brands particularly seek out, along with a growing base of omnichannel customers, who shop in store and online and spend more overall. For a brand, it is the ideal retail media terrain: reaching the customer online and measuring the effect all the way into the store.
With more than 2,000 stores at the heart of peri-urban and rural areas, Coopérative U extends Unlimitail's grocery offer well beyond city centres. Brands thus have access to one of the broadest grocery retail media offers in France, run end to end by a single team at Unlimitail.
"With Coopérative U, more than a third of the French grocery market is brought together, a power now accessible to all brands on our platform. They run their campaigns there from brief to measurement, with an operational simplicity that directly benefits their performance."
Alexis Marcombe, CEO of Unlimitail
Offer details, timeline and next steps
Unlimitail's teams will support brands from the coming days to prepare their 2027 media plans. The first campaigns will run on Coopérative U's digital inventory from January 2027.
From January, brands will have access to the most diversified offer on the market, combining sponsored products, banners and videos to meet every objective, from awareness through to conversion.
