About Didier Truchot

Didier Truchot is the founder of Ipsos, the global market research and polling group listed on Euronext Paris. Born in Boulogne-Billancourt in 1946, and educated in economics at Paris-Sorbonne University, he began his career in 1968 as a researcher at IFOP, the French Institute of Public Opinion. That early experience in opinion research and consumer insight laid the foundation for his later career as a business builder and strategic leader. He founded Ipsos in Paris on October 1, 1975, with an innovative idea for the time: to work very closely with clients and provide them with practical, decision-ready research. Initially focused on advertising effectiveness and media research, the company gradually broadened its scope. Under Truchot’s leadership, Ipsos expanded internationally and diversified into public opinion, social research, consumer studies, and client experience. The group built a strong global footprint and developed into one of the major players in the research industry. Truchot also oversaw periods of strategic growth and transformation, including the launch in 2018 of the “Total Understanding Project,” a program centered on platforms, data, and insights. This strategic shift strengthened Ipsos’ positioning and its ability to deliver reliable information for a deeper understanding of Society, Markets, and People. From a governance perspective, Didier Truchot was for many years the central figure at Ipsos, serving over time as co-chairman, Chairman of the Board, and Chief Executive Officer before handing executive leadership to Ben Page in November 2021. He remained closely associated with the company as founder and long-standing board leader. More recently, Ipsos announced that he stepped down as Chairman in 2026 for health reasons, while staying on as a director and principal shareholder. His career is a notable example of a founder-entrepreneur who shaped not only the growth of a listed company, but also its independence, strategic discipline, and corporate identity.
