360i is elevating president Jared Belsky to CEO and making current CEO Sarah Hofstetter the agency's chair. Bryan Wiener, who had held the chairman role, is leaving to become comScore's chief executive after 13 years of leadership at the agency.
The Dentsu Aegis Network-owned shop which works with clients including HBO, National Geographic, Chili's and DSW in late March also shifted CMO Abbey Klaassen to president of the agency's New York headquarters.
Belsky joined 360i in 2008 as managing director of the Atlanta office and has been president since 2013. Hofstetter has been at the agency for more than a decade, and has held the CEO title for nearly five years.
