Omnicom Media has officially launched Hearts United, a new global media agency created by combining its Hearts & Science and Mediahub networks.
The new agency will operate across 40 markets and has approximately $9.1 billion in billings for 2025. The launch follows strong growth by both Hearts & Science and Mediahub in recent years.
According to an Omnicom Media press release issued on August 28, 2026, Hearts & Science increased its billings by 50 percent between 2021 and 2025, while Mediahub recorded 33 percent growth during the same period. The new agency will focus on helping brands manage media across platforms, creators, communities, commerce and AI.
Hearts United will use AI in its workflows and combine media, data, technology, creativity and commerce to help brands grow. The agency will also focus on connecting different media channels instead of treating them separately.
Nicole Estebanell, former CEO of Mediahub US, will lead Hearts United in the US, while Ross Jenkins, who previously led Mediahub in EMEA, will head the agency in the region. Leaders for APAC and LATAM are expected to be announced in the fourth quarter.
