Hearts & Science

Specialist data-led media agency within Omnicom Media Group; smaller than OMD and PHD but differentiated by deep data science capabilities and agile operating model

Hearts & Science is a data-led media agency launched by Omnicom Media Group in 2016, purpose-built to win and service AT&T's estimated $3 billion media account. The agency was designed from the ground up around data science, audience intelligence, and agile marketing principles, differentiating itself from traditional media agencies by embedding data analysts and technologists directly into planning teams. Its name reflects the dual philosophy of combining analytical rigor ('Science') with human insight and creativity ('Hearts'). The agency quickly grew beyond its founding client, adding major brands such as Procter & Gamble, Gap, and others to its roster. It operates as a specialist agency within Omnicom Media Group alongside OMD and PHD, occupying a mid-tier position in terms of scale but punching above its weight in data sophistication. Hearts & Science has been recognized for its use of first-party data, advanced attribution modeling, and cross-channel media optimization capabilities. Following Omnicom's announced merger with Interpublic Group (IPG) in late 2024, Hearts & Science continues to operate as an active entity within the combined Omnicom Media Group structure. The agency's positioning as a data-first, agile media shop remains its core identity, and it continues to serve large enterprise clients requiring sophisticated audience targeting and media investment optimization across traditional and digital channels.
