Omnicom agencies

Omnicom is a New York-based marketing and sales group listed on the NYSE. It completed its acquisition of Interpublic in November 2025, so agencies that used to belong to IPG now sit under Omnicom.

0 agencies in the directory belong to Omnicom. Each profile links to the page its membership was read on, starting from Omnicom’s own site. A group name on the door doesn’t tell you who will do the work, so read each profile on its own.
