Chris Kuenne is stepping down as chairman of Rosetta, the digital agency he founded in 1998. Kuenne had also been CEO of the agency until April of 2013. He was succeeded in that role by Tom Adamski.

The agency is now part of Publicis Groupe, which bought the Princeton, N.J.-based firm in 2011 for $575 million.

“Through vision and passion, Chris was able to build and scale a truly unique agency model,” said Publicis Groupe CEO Maurice Levy. The shop now employs more than 1,000 staffers across 10 offices around the world.

Kuenne said he would spend more time running a new private equity firm, Rosemark Capital Group, that will focus on investing in tech start-ups. Among other projects, the firm has launched a study evaluating the commonalities of successful tech-focused entrepreneurs -- which will be published in about a year, according to the company.

Kuenne has also signed on as a professor of technology and entrepreneurship at Princeton University.

Separately, Rosetta said Thursday it had promoted Tammy Soares to Managing Partner. She will work alongside Managing Partner Grant McDougall overseeing the Technology and Telecommunications Industry Group, which is the agency’s largest in terms of revenue.
