Ella McWilliam

Ella’s career is defined by the rare ability to build commercial success without ever losing sight of people, purpose and culture. At just 26, she co-founded Full Fat in 2012 alongside Megan Morass, and over the past 14 years has grown it into one of the UK’s leading creative and culture communications agencies. Under her leadership, Full Fat has achieved consistent year-on-year growth, becoming a multi-million-pound business while remaining values-led and fiercely people-first. Her resilience was most visible in 2021, when Covid wiped out 75% of revenue overnight. Ella led with calm, empathy and decisive action, stabilising the agency and driving a remarkable recovery that saw 2021 become the most successful year in Full Fat’s history. She has also built an outstanding workplace: over the past three years, 100% of the team have said Full Fat is a great place to work, reflecting a culture rooted in trust, accountability and inclusion. Ella’s leadership has been recognised through B Corp certification in 2024 and DEI awards from PRWeek and PR Moments. Beyond the agency, she is actively shaping the industry’s future, founding FOLD in 2025 and co-founding Her Table to create space for learning, community and change. Her work has earned top-tier recognition, including PRWeek Boutique Agency of the Year 2025 and three consecutive appearances in PRWeek’s Power Book.
