Ipsos was founded in Paris in 1975 by Didier Truchot, an economist. Jean-Marc Lech, a philosopher and sociologist, joined as Co-President in 1982.
Their goals were to make survey-based research one of the primary means to understand contemporary society; and to make Ipsos a strategic partner for those who wished to better understand the world and play an active part in it.
Ipsos had established itself as a successful and innovative company in France by the end of the 1980's, with a recognized brand in public opinion and media research, advertising research and an omnibus survey.
In 1989, the time was right to launch onto the international scene to enable their global clients to compare data across countries.
By mid 1990's, Ipsos companies were prominent in the five major European markets of France, Germany, Italy, Spain and the UK. There were also Ipsos companies in Belgium, Portugal, Hungary and Poland.
The push to develop further afield began, with companies and investments in the USA, Latin America and the Middle East. In late 1997, Ipsos acquired ASI, one of the USA's leading advertising research companies; while in Latin America, the Novaction companies were integrated within the Ipsos network.
In 1999, Ipsos started doing business in the Asia-Pacific region.
International expansion accelerated and, between 2000 and 2008, the Group acquired 44 companies and opened 16 new offices.
Currently Ipsos has offices in some 70 countries and operates in over 100.
