Hearts & Science

Specialist data-driven media agency within the Omnicom ecosystem, smaller in scale than OMD and PHD but differentiated by analytics-first methodology

Hearts & Science is a data-led media agency founded in 2016 by Omnicom, purpose-built to win and service the AT&T account. The agency was designed from the ground up around a data-first philosophy, integrating advanced analytics, audience science, and real-time optimization into its core media planning and buying capabilities. It operates at a specialist scale, positioned between boutique shops and the full breadth of Omnicom's larger media networks like OMD and PHD. The agency differentiates itself through a proprietary blend of data science, technology partnerships, and human creativity, enabling clients to connect with consumers across linear TV, digital, streaming, and emerging channels. Hearts & Science has expanded its client roster beyond AT&T over the years to include major brands across retail, entertainment, and consumer goods, while maintaining its identity as a precision-focused, analytically rigorous shop. Hearts & Science operates as a distinct agency brand within the broader Omnicom Media Group structure, benefiting from Omnicom's scale in data, technology, and negotiating power while maintaining its own leadership, culture, and go-to-market identity. The agency is headquartered in New York City and has offices across major U.S. markets.
