Tim Hipperson has resigned as CEO of ZenithOptimedia UK after just eight months in the role, the company has confirmed.
The news follows the recent loss of the £135m UK and Ireland L’Oréal account to Maxus.
Hipperson will continue to work on consulting projects for the network and he is in discussions with Publicis Groupe about “potential leadership opportunities”, a statement said.
Hipperson said: “In my time at ZenithOptimedia, we have formulated a business plan to help redefine the role of the media agency with data, strategic consultancy and content at its core.
“The media industry has a unique opportunity to change the way the communications industry works and I have helped set ZenithOptimedia on that course.
Coinciding with the news, ZenithOptimedia has created a new management board based in the UK to oversee both UK and global operations.
Global managing partner Belinda Rowe has been named chairman of the board, and she will be joined on it by Mark Howley, managing director of ZenithOptimedia UK; Natalie Cummins, managing director of Optimedia UK; Charlotte Frijns, chief finance officer of ZenithOptimedia Worldwide and UK; Sean Healy, global communications planning director at ZenithOptimedia; and Tom Cijffers, who has been appointed managing director of Zenith UK.
Cijffers, currently managing director of client service and ZenithOptimedia Worldwide, is taking over the role from Stephen Farquar, who has been named managing director of Zenith China.
Steve King, CEO, Worldwide, ZenithOptimedia, said: “Since taking up the global managing partner role in 2010, Belinda Rowe has transformed our Worldwide operation.
“The new group structure she will lead will help us to better deliver our Live ROI promise to clients and to build on our specialisms, such as branded content, data and digital performance marketing.”
