About the Founders

Mrs Katie Massie-Taylor

Katie Massie-Taylor is an entrepreneur and strategic growth leader focused on building products that solve real, everyday challenges for families. As co-founder of The Flourishing Brain, she brings a strong track record of translating insight into practical, engaging tools that people actually use.

Katie began her career in the City as a derivatives broker, where she developed a strong commercial and analytical foundation. She is FSA qualified and CELTA qualified, reflecting both her financial training and early experience in education.

She later moved into consumer tech and community-building, most notably as co-founder of Mush, the UK’s leading app for mothers, which she scaled into an international platform and successfully exited to Mumsnet. Since then, she has worked across a range of ventures spanning wellbeing, digital platforms, and brand development, with a particular focus on women and family life.

Her work is driven by a belief that powerful ideas only matter if they are accessible and actionable. Through The Flourishing Brain, Katie is focused on bringing together science and real-world application to help parents better understand and support their teenagers.

Katie lives in Wiltshire with her husband and three daughters, and spends as much time as possible outdoors, usually around sport, fresh air, and family life.

Dr Katy Granville-Chapman

Katy Granville-Chapman’s interest in the brain, flourishing, and leadership began in high-pressure environments early in her career, where she saw how relationships, mindsets, and character shape whether people struggle or thrive. After serving in the British Army in Iraq, Europe, and the United States, she moved into school leadership roles focused on performance and development, and later completed a Doctorate at Oxford University exploring leadership and flourishing. She now teaches at Oxford, is a Senior Fellow of the Flourishing Network, hosted by the Human Flourishing Program at Harvard, and is a Deputy Head at Wellington College.

Katy co-founded a global youth leadership movement now active in over 100 countries and works internationally at the intersection of flourishing and wellbeing science, education, and leadership. Through her writing and teaching, she translates research into practical ways adults can help young people and teams to grow in character and flourish. A former GB synchronised swimmer, current GB age-group triathlete and lover of skiing, surfing, mountain biking, and ballet, she is driven by a simple question: how do we create the conditions for people—and their brains—to thrive?
