Greg Smith, the CIO of McCann Worldgroup who founded and was CEO of an affiliated creative technology unit called Split, has left to become global CIO at French market research company Ipsos.
A successor at Worldgroup has not yet been named; earlier this year Split was absorbed into the company's Creative Technology Group which is run by Mark Fallows, who was named Worldgroup's chief technology partner a year ago.
A Worldgroup exec confirmed the change; Smith could not be reached for comment.
Smith created Split in January 2010 to develop global marketing and technology partnerships with agencies and marketers and to produce new product offerings. It was founded as an independent IPG revenue center but was aligned with Worldgroup, which at that point was still run by former CEO John Dooner. Smith worked with former McCann N.Y. chief creative officer Joyce King Thomas in testing out the concept. King Thomas has since left McCann ; last November Linus Karlsson was brought in as chairman, CCO of McCann N.Y. , as well as London, by Worldgroup’s new chief Nick Brien .
Smith joins Ipsos after it bought Synovate from Aegis this summer,  making Ipsos the world’s third-largest market research firm. He had been affiliated with IPG companies since December 2001, working as CIO at Universal McCann and chief technology catalyst at Mediabrands before joining Worldgroup as CIO in 2004.
