Hearts & Science

Hearts & Science has consistently outperformed the market and was crowned 2024’s fastest-growing agency, delivering +74% year-on-year billings growth. But growth alone was not the goal. Our focus was simple: ensuring Hearts became not just bigger, but better, by delivering work that truly works.

Work that drives growth for clients’ brands and businesses, challenges the industry, earns critical acclaim, attracts talent, inspires people to join Hearts, and contributes positively to the world. In the past year, Hearts delivered +42% organic revenue growth, +7% headcount growth and £42m in new billings, including wins and extensions with Go.Compare, Clorox, Red Equipment, Trip.com, Future Publishing and TJX. Client satisfaction reached 9.0 versus a 7.7 industry average, while employee churn stood at 16.7% compared with an industry average of 23.2%. Sixty-seven percent of entry-level hires came from diverse backgrounds. Creatively and strategically, Hearts achieved 76 award shortlists and 32 wins, a 60% year-on-year uplift, with talent recognised across the industry. Two achievements stood out: being named Agency of the Year at the AdWanted Research Awards and securing IPA Effectiveness Accreditation for a second time. Above all, we are proud of delivering effective campaigns, generating over £1.2bn in revenue and ROAS exceeding £5 for clients.
