Didier is Ipsos Co-Chairman and Chief Executive Officer. He graduated in economics and started his career in 1969 with the IFOP institute in Paris (a well-known market and opinion research company in France), where he met Jean-Marc Lech, his future business partner. From 1972 to 1975 he was Research Director at the IRSEC institute. In 1975, he created Ipsos.
Didier, who originated a policy of offering standardized research products, first developed Ipsos in the fields of advertising and media research. In 1982, when Jean-Marc joined the company, Ipsos started offering public opinion research and, since then, added to its portfolio two other specialties – marketing and CSM/CRM research.
Didier and Jean-Marc are co-chairs of Ipsos, which now ranks as the world’s third largest survey-based research group.
