Le Groupement Mousquetaires selects Médiaperformances as its in-store Retail Media partner to accelerate its omnichannel strategy in France and across Europe.

Paris, December 17, 2025 – Following a competitive tender process, Le Groupement Mousquetaires has appointed Médiaperformances as its strategic partner for the deployment and management of in-store Retail Media for Intermarché and Bricomarché. This multi-year partnership will be rolled out across more than 2,000 stores in France, Belgium, Poland and Portugal, in close collaboration with Infinity Advertising, the Group’s Retail Media sales house. This alliance marks a key milestone in Le Groupement Mousquetaires’ ambition to build a robust, scalable and performance-driven Retail Media ecosystem, fully integrated into its omnichannel strategy. By combining Infinity Advertising’s data and commercial expertise with Médiaperformances’ in-store execution capabilities, the partnership aims to deliver a seamless and consistent brand experience across physical stores, retailers’ digital platforms and the wider digital media landscape.

A data-driven, omnichannel Retail Media proposition
Together, Infinity Advertising and Médiaperformances will offer brands a coherent, data-led activation framework, aligned with key consumption moments and shopper journeys. The objective is to strengthen the strategic role of in-store media while ensuring continuity between on-site, off-site and in-store activations, supported by unified measurement standards. In close coordination with Infinity Advertising, Médiaperformances will be responsible for the roll-out, orchestration and optimisation of in-store Retail Media solutions, contributing to revenue diversification for Intermarché and Bricomarché. Activations will combine digital in-store media (DOOH) and print formats, with a clear roadmap to progressively digitalise stores and enhance campaign performance and monetisation.

“Our ambition is to establish Le Groupement Mousquetaires as a leading Retail Media player in Europe. This partnership fully supports our strategy to diversify revenues and create sustainable value for our banners, store owners, brand partners and shoppers,” said Stéphane Sinopoli, Director of Data Monetisation at Le Groupement Mousquetaires. Complementary expertise to scale Retail Media performance
Infinity Advertising will oversee the co-commercialisation of Retail Media offerings, leveraging its proprietary transactional data and audience expertise, while Médiaperformances will ensure best-in-class in-store execution. Both partners will jointly deliver end-to-end measurement, covering in-store exposure, retailers’ digital environments and extended digital ecosystems.

“This partnership strengthens our ability to deliver a fully integrated, measurable and performance-oriented Retail Media proposition to brands. It represents a new phase in the development of Infinity Advertising as a fast-growing European Retail Media reference,” commented Alban Schleuniger, Chief Executive Officer of Infinity Advertising. Recognized as a leader in in-store communication, Médiaperformances was selected for its strong operational excellence, deep understanding of retail environments and proven ability to deploy solutions at scale. Its collaborative mindset and capacity to build operational synergies with Infinity Advertising were decisive in Le Groupement Mousquetaires’ choice.

“We are proud to support Le Groupement Mousquetaires in deploying its in-store Retail Media strategy across four countries and two major retail verticals. This partnership validates the relevance of our model, combining data, technology and field expertise to accelerate the digital transformation of in-store Retail Media and deliver more relevant, measurable and high-performing campaigns at the point of sale,” said Claire Koralewski, Chief Executive Officer of Médiaperformances. Already deeply engaged in the digitalization of in-store Retail Media through its strategic partnership with VusionGroup, Médiaperformances reaches a new milestone with this agreement. The partnership strengthens its market position, expands its footprint beyond the grocery sector and confirms the international recognition of its expertise.

This collaboration unlocks a powerful, fully integrated and measurable Retail Media environment for brands, covering the entire shopper journey and aligned with sharp business objectives.
