The Swiss firm, founded in 1943, has annual turnover of US$5m and is the fifth acquisition made by Leger Marketing in the last 10 years after it bought Canadian firms Criterion, Criterion Research, Claros Research and US-based Arc Research.

Isopublic will continue to be led by president Mattias Kappeler, who also serves as vice president of the Worldwide Independent Network of Market Research agencies. Leger boss Jean-Marc Léger is president of the network. He becomes chairman of Isopublic post-acquisition.

Léger (pictured) said: “The acquisition of Isopublic is a strategic move for Leger Marketing, giving us access to international clientèle based in Switzerland. Our presence in Europe also allows us to support our North American clientèle in European markets – clients such as Johnson & Johnson, Microsoft, Merck, Wells Fargo and Walmart.”

Kappeler added: “Leger Marketing’s arrival allows Isopublic to benefit from their unique technological expertise in online polling, as well as their research models and advanced statistical analysis.”
