Tinuiti began life in 2004 as Elite SEM and adopted its current name after consolidating with acquired agencies CPC Strategy, Email Aptitude, and OrionCKB. The company positions itself as the largest independent full-funnel performance marketing agency in the United States, reporting more than 1,200 employees, roughly $4 billion in annual digital media under management, and around $235 million in annual revenue. The business is backed by New Mountain Capital, Antares Capital, and Mountaingate Capital. Headquarters sit in New York City at 111 West 33rd Street, though the workforce is roughly 99% remote following a deliberate post-pandemic shift away from physical offices. Abbey Klaassen took over as CEO in April 2026, succeeding Zach Morrison. A separate offering called Foundation serves startups and SMBs not yet ready for the enterprise practice.
