Specialist data-led media agency within Omnicom Media Group, positioned between large network agencies and boutique shops; now merged into Hearts United
Hearts & Science was a data-driven media agency network launched by Omnicom Media Group in April 2016 as its third agency network, alongside OMD and PHD, with Procter & Gamble as its inaugural client; AT&T followed later in 2016. It was headquartered in New York. On August 28, 2026, Omnicom Media combined Hearts & Science with Mediahub to form Hearts United, a 40-market network; the Hearts & Science websites now redirect to heartsunited.com. Between 2021 and 2025 Hearts & Science grew its billings by 50%, according to Omnicom Media. In Australia, Hearts & Science took the Hearts United name. Its UK company, Hearts & Science Ltd, kept its name.
