Dentsu digital shop 360i has promoted president Sarah Hofstetter to U.S. CEO.
The agency's current CEO, Bryan Wiener, will become global CEO and chairman. Jared Belsky, formerly evp, takes Hofstetter's U.S. president title.
The new title means added responsibility for two longtime executives at the shop, as Wiener shifts focus to the agency's global expansion and to launching new services.
"Sarah and Jared have proven themselves to be incredible leaders, operators, and client strategists," said Wiener.
Hofstetter has been with the agency eight years, and Belsky for five.
The agency has had a strong new business run in 2013, adding work on clients like Subway, HBO and Ben and Jerry's. It also launched its first outposts abroad with help from Dentsu, opening shops in London, Toronto and Sao Paulo.
Its core presence remains in the U.S., with 430 staffers in New York, 120 in Atlanta and 45 in Chicago. London employs 20, Toronto houses five, and Sao Paulo, the newest, has four.
Hofstetter, based in 360i's New York office, will continue to oversee the agency's global strategy and social marketing practice, which has in recent years helped it gain broad recognition for work like Oreo's Daily Twist campaign and the Super Bowl blackout tweet. The agency's clients also include Oscar Mayer and Coca-Cola.
Hofstetter's new role adds oversight of all aspects of the agency's U.S. business, including the agency's search, media, and analytics practice. The agency's creative department will also now report to her.
Belsky, based in Atlanta, will continue to run 360i's search, media and analytics practice. He'll also take on some strategic and operational aspects of the agency's brand marketing and social practice, as 360i moves to combine the two—previously run as separate business units—into one. "We're now bringing those together to reflect many more of our clients having integrated owned, earned and paid [media]," said Wiener.
