360i

360i is a digital advertising agency brand operated within the Dentsu network. Founded in 1998 and acquired by Dentsu in 2010, 360i was folded into Dentsu Creative in 2022. In June 2026, Dentsu revived the 360i name as a lean, four-person, fixed-fee unit — a departure from the traditional agency model, led by managing director Christine Cotter and aimed at winning back work going to smaller, specialized shops.
