Hearts & Science

Garrett O'Reilly

2023 saw Garrett create a vision and culture that has inspired Hearts to become the UK's fastest growing media agency winning over £200m in net new business wins - surpassing the combined growth of its 2nd, 3rd, 4th and 5th closest competitors. Having established a new leadership team to enrich Hearts’ culture and reshape agency operations to better service client demands, he has overseen over 40% growth in organic revenue this year.

A visible and empathetic leader, Garrett has created in Hearts a new kind of agency with a culture that encourages innovative work, challenges conventions, leverages data and technology, and embraces the future of media.
