Euro RSCG 4D Discovery, the data and analytics arm of Euro RSCG Worldwide, has added Clive Maclean as chief executive officer. Maclean replaces Zain Raj. Once a ringleader in the Euro RSCG management team, Raj is leaving to take what is described by Euro RSCG as "a leadership role" in an independent company of Lake Capital, a private equity firm in Chicago.

Most recently, Maclean was the head of his own consultancy, Clive Maclean Consulting. Prior to that, he served as North American president of The Marketing Store, where he worked with clients such as McDonald's, Coca-Cola and Allstate. Maclean also has previously been president of FCB Direct in Chicago and Leo Burnett Interactive in South Africa, where he's originally from.

"We're very excited to be able to bring in somebody who has a track record of driving growth for some of the nation's leading marketers," said Ron Bess, president and COO of Euro RSCG North America.
