Intermarché

Jean-Pierre Le Roch launched Intermarché in 1973 to give independent grocers a fighting chance against massive hypermarket chains. The cooperative model let local merchants pool their buying power while keeping their stores locally owned and managed. This structure allowed the brand to spread rapidly across France, creating a network that prioritized regional access over centralized control.

By 2024, the chain had grown into the third-largest retailer in the country with a 14.3% market share. It operates more than 1,800 locations ranging from small convenience shops to large hypermarkets. The company also runs a successful click-and-collect service known as Drive, which lets customers order groceries online and pick them up at designated spots without entering the store.

The group faces significant scrutiny following a major cyberattack in October 2026. Hackers manipulated Danfoss refrigeration controllers in hundreds of stores, causing temperatures to spike and spoiling millions of euros worth of food. Some freezers caught fire during the incident, highlighting critical vulnerabilities in industrial internet equipment used by European retailers. [edit]
