Chris Kuenne, who founded Rosetta in 1998, has stepped down from his non-executive role with the Publicis Groupe shop.
Kuenne negotiated a $575 million sale to Publicis in 2011, and served as CEO of the interactive agency until last May.
The three-decade marketing veteran looks to turn more attention to Rosemark Capital Group, a private equity firm he launched last year. He helped Princeton, N.J.-based Rosetta land digital marketing accounts in categories such as healthcare (Novartis, Bristol Myers-Squibb, among others); retail (Office Max and Hickory Farms); and financial services (Nationwide, M&T Bank, etc.).
"Chris started Rosetta 15 years ago based on the idea of empowering marketers through a deep understanding of consumer behavior," said Rosetta CEO Tom Adamski, in a statement. "That founding idea led us to where we are today, the only agency in the world that can combine the insights and technology of data-driven marketing with the ideas and experiences of next-generation storytelling."
