Hearts & Science
Hearts & Science is a media agency for planning, buying and measuring cross-channel campaigns.
Analyst Perspective
Hearts & Science is a media agency within Omnicom Media Group that provides managed services across media planning, media buying, paid search, paid social, analytics, marketing science, CRM-related programmes, content marketing and strategic consulting. Its offer is aimed at advertiser brands and senior marketing teams that want media strategy, activation and measurement tied together through a single agency relationship. The company makes money primarily from agency fees linked to planning, buying, analytics and consulting engagements, with additional economics likely tied to managed media spend and buying scale within the Omnicom network. Its customers are business buyers rather than consumers, especially enterprise marketing organisations seeking cross-channel campaign execution and performance accountability.
