Carrefour

Carrefour is Europe's largest retailer with $90 billion in annual revenue operating 12,000+ stores across 30 countries. The French chain, founded in 1958 in Annecy, invented the hypermarket format and remains the market leader in France, Belgium, Spain, and Brazil. Its strategic pivot toward e-commerce and discount formats has helped it navigate intense competition from discounters like Lidl and Aldi.
