Médiaperformances accelerates international expansion with the opening of five subsidiaries in Europe

Paris, 8 September 2026 – Médiaperformances has reached a new milestone in its development with the opening of subsidiaries in Spain, Poland, Portugal, Italy and the United Kingdom. This acceleration reflects the Group’s ambition to strengthen its position in the European retail media market and support retailers and brands in new markets and sectors.
Under the leadership of Claire Koralewski, CEO of Médiaperformances, the Group is continuing to roll out its model internationally. The International Division, headed by Stefano Ghidoni, is tasked with steering and accelerating this European expansion, working closely with local teams and management.

A new European dimension for Médiaperformances

This international acceleration forms part of a growth trajectory already underway and driven by several key market wins. Beyond its long-standing expertise in the food retail sector, Médiaperformances is now extending its know-how into new retail and consumer sectors, including DIY and beauty. New retailers will thus gradually enrich the Group’s portfolio across these various European markets.
This diversification, combined with the opening of these five subsidiaries, will enable Médiaperformances to deploy its expertise on a larger scale while drawing on local teams and an in-depth understanding of the specific characteristics of each market.

“The simultaneous opening of five subsidiaries marks an important milestone in Médiaperformances’ history. Our international expansion is now a reality, driven by the trust of major retailers, the strength of our business model and our ability to extend it to new markets and sectors. We are becoming Europe’s leading omnichannel Retail Media player, combining scale, innovation and performance with close relationships with retailers and brands,” said Claire Koralewski, CEO of Médiaperformances

His role will be to lead Médiaperformances’ international development, support the growth of its various subsidiaries and facilitate the rollout of a common model tailored to the specific requirements of each market. He will also directly oversee the development of the Italian market.
