Hearts United

Newly launched specialized media agency within Omnicom Media's portfolio, positioned to deliver integrated, data-driven media solutions at scale

Hearts United is a global media agency network within Omnicom Media, launched on August 28, 2026 by combining Omnicom Media's Hearts & Science and Mediahub networks. It operates across 40 markets and represented approximately $9.1 billion in 2025 billings, and is headquartered in New York. It sits alongside Omnicom Media's other agency networks — OMD, PHD, Initiative and UM — and draws on the group's shared scale in data and technology, identity, commerce capabilities and talent. Omnicom Media describes its approach around four principles: outcomes-oriented commercial models, AI embedded in workflows, planning across the platforms, creators and commerce environments where attention moves, and senior-led teams. Its launch leadership was regional rather than global: Nicole Estebanell (U.S. CEO) and Ross Jenkins (EMEA CEO), both previously Mediahub leaders, with Garrett O'Reilly as UK CEO and Dominik Scholta as Germany CEO; APAC and LATAM leaders were due in Q4 2026. In Australia, Hearts & Science took the Hearts United name while Mediahub Australia continues as a separate agency.
