Thierry Garnier

Operator

Thierry Garnier is best known as the CEO of Kingfisher plc, the pan-European home improvement retailer operating brands such as B&Q and Screwfix, where he has led a significant digital transformation and omnichannel retail strategy since 2019. His leadership has positioned Kingfisher as a data-driven retailer, with growing investments in retail media and first-party data monetization — areas of increasing relevance to the AdTech ecosystem as retailers build out commerce media networks to compete with Amazon Advertising and Walmart Connect. Prior to Kingfisher, Garnier spent over two decades at Carrefour, one of the world's largest retail groups, where he held senior leadership roles including CEO of Carrefour China. His experience scaling retail operations across diverse international markets gave him deep expertise in consumer behavior, supply chain optimization, and the intersection of physical and digital commerce. These foundations have informed his approach to leveraging customer data assets for both operational and advertising purposes. Note: The query associates Garnier with Ahold Delhaize, but based on publicly available information, Thierry Garnier is associated with Kingfisher plc as CEO. If this refers to a different Thierry Garnier at Ahold Delhaize, specific details could not be verified with confidence. The information above reflects the most prominent public figure by this name in global retail leadership.
