Mumbai: Lintas Media Group chairperson and chief executive Lynn de Souza is leaving the media buying and planning agency after a 17-year stint.

IPG Mediabrands, the holding company of Lintas Media Group, in a statement on Monday said that De Souza, “an active participant in the non-profit space for several years, has expressed her desire to become a social entrepreneur. She will announce the launch of a pioneering new initiative for the development sector in early 2013, and will be leaving IPG Mediabrands at the end of November."

Meanwhile, Shashi Sinha, chief executive of Lodestar UM, also a part of IPG Mediabrands, has been appointed as the chief executive of IPG Mediabrands India. “Initiative, BPN, Reprise and the Outdoor company will all now report to him, in addition to his existing charge, Lodestar UM. This both represents the commitment IPG Mediabrands has made to the Indian market, and recognizes that Shashi, an IPG veteran of over 20 years, has contributed greatly to that growth," said the company in the same release.
