France's Valiuz Takes Its Retail Media Network to Poland
Updated: 6 days ago

Valiuz, the French retail-data and retail-media powerhouse backed by the Mulliez family and the Groupement des Mousquetaires, is expanding into Poland, extending a European push that already spans Spain, Romania and Germany.
What Valiuz is doing
Valiuz is extending its retail media operations into Poland, the latest leg of an aggressive European expansion. The company pools first-party shopper data across major French retail groups and has publicly set out to become Europe's retail-media leader.
Poland joins a footprint that already includes Spain, Romania and Germany, giving Valiuz a cross-border, cross-retailer data network that few European rivals can match.
Why retail media is the land grab of 2026
Retail media is the fastest-growing corner of the ad market, as retailers turn first-party purchase data into advertising revenue while third-party cookies fade. European retailers are consolidating their ad businesses precisely to compete with Amazon's scale.
Valiuz's pitch is breadth: one network spanning several retailers and now several countries, sold to advertisers who want reach and measurement without stitching together a dozen separate deals.
The Marketing Minute read
For advertisers, more retail-media networks mean more first-party reach but also more fragmentation to manage. The networks that win will be the ones offering genuine scale and clean, comparable measurement across borders.
Our take: stop treating retail media as a bolt-on and give it a strategy of its own. Demand transparent measurement, test the new European roll-ups against the incumbents, and do not let every retail euro default to the biggest platform out of habit.
Quick FAQ
What is Valiuz?
A French retail-data and retail-media company backed by the Mulliez family and the Groupement des Mousquetaires, pooling shopper data across major retailers.
What is retail media?
Advertising sold by retailers using their own first-party shopper data, on their sites and apps and increasingly on TV and across the open web.
Why expand across Europe?
Scale. A cross-border, cross-retailer network is more attractive to big advertisers and better placed to compete with Amazon.
Retail media is the quiet giant of this decade's ad market, and Europe is finally building players big enough to matter. Valiuz's bet is scale across borders and retailers, and for advertisers that is a real alternative to sending every retail-media euro to Amazon by default. — Daniel Nikolla, Founder of Merx Marketing
Retail media's European land grab is on, and the networks that offer genuine cross-border scale and clean measurement will take budget that used to flow automatically to the biggest platforms.
Is retail media just a line item in your plan, or a core channel with its own strategy and measurement?
