Omnicom Media, an Omnicom (NYSE: OMC) Connected Capability, today officially launched Hearts United, a new global media agency created through the combination of its Hearts & Science and Mediahub networks.
Bringing together two high-growth challenger organisations with complementary capabilities, cultures and geographic strengths, Hearts United is built to help ambitious brands navigate a media environment where influence moves continuously across platforms, creators, communities, commerce, and AI.
“Hearts & Science helped pioneer data-driven decision-making, while Mediahub broke new ground by proving media could serve as a creative platform,” says Omnicom Media CEO Florian Adamski. “In bringing them together as Hearts United, we have created a new globally scaled network built from complementary strengths, approaches and footprints, and grounded in the shared principle of putting client growth at the heart of every decision.”
The new agency – which operates across 40 markets and represents approximately $9.1 billion in 2025 billings – launched following sustained growth at both organisations. Between 2021 and 2025, Hearts & Science increased its billings by 50%, while Mediahub grew 33% – momentum that has continued into 2026. As result, the new agency debuts with one of the best new business performances in the industry as tracked by the COMvergence real-time dashboards, currently ranking #1 in the US YTD with $294m in total new business (wins minus losses, including retentions); and #3 globally and in EMEA with $567m and $242m, respectively, outperforming agencies that are up to three times its size.
Four principles define the new agency’s approach:
- Outcomes-oriented: An evolving commercial model connects the agency’s success with client growth, putting accountability into the operating model.
- Predictive by design: AI is embedded into workflows and the operating model to expand capacity, strengthen human judgment and give talent more time to solve higher-value problems.
- Ecosystem mastery: Teams plan holistically across the platforms, communities, creators, and commerce environments where attention and influence move, rather than treating channels as isolated decisions.
- Focused and senior-led: Expert teams work as extensions of clients’ organisations, reducing silos and handoffs while bringing senior guidance and diverse expertise to the work.
Like its sibling Omnicom Media agencies OMD, Initiative, PHD and UM, Hearts United will leverage the singular advantages and assets of the world’s largest global media network in scale, data & technology, identity, commerce capabilities, and talent to deliver disproportionate growth for its clients.
Hearts United will be led in EMEA by Ross Jenkins, who previously led Mediahub across the region. During his tenure as EMEA CEO, Jenkins expanded Mediahub’ s footprint into new markets, accelerated its growth, attracted major international clients, and established a reputation for combining challenger thinking with operational excellence. He has also built cross-market teams around an entrepreneurial culture, a model that will carry into the new Hearts United EMEA organisation.
“With Hearts United we’re building the kind of agency we believe clients increasingly need to connect with people in motion across an AI-mediated world – one that discovers what others overlook, that finds the truths hidden in behaviour, and that dares to find an original way in, with media as the creative platform,” said Jenkins. “It is an agency where curious people are encouraged to challenge convention, experiment and solve problems creatively, and where ambitious clients come to find undiscovered and unexpected answers.”
Hearts United joins the Omnicom Media agency portfolio as the group has the best 2026 YTD total new business performance among all global media groups for 2026 – including earning more new client billings ($4.1b) than any other group – resulting from a streak of wins including Adidas, Delta, Dyson, IBM, Mark Anthony Brands, Novo Nordisk, On, and Subway.
