Throughout his career, Jeff Kreisler has built a reputation for transforming behavioural science into practical business advantage. His work focuses on helping organisations understand why people often make irrational decisions and how behavioural insights can improve leadership, communication, customer experience, financial wellbeing, and organisational performance. Drawing on research from psychology, economics, and neuroscience, this respected speaker demonstrates how small changes in behaviour can create significant improvements in business outcomes.

As Head of Behavioural Science at J.P. Morgan Private Bank, Jeff works with executives, investors, advisors, and business leaders to overcome decision biases, improve strategic thinking, and strengthen long-term planning. His expertise spans behavioural finance, consumer psychology, organisational behaviour, negotiation, employee engagement, and change management. Jeff is particularly recognised for showing how behavioural economics can influence everything from sales and marketing to innovation, pricing, wellbeing, and workplace culture.

A former professional comedian and winner of the Bill Hicks Spirit Award for Thought Provoking Comedy, he delivers keynote presentations that are insightful, relatable, and genuinely entertaining. Audiences leave with practical frameworks for making better decisions, reducing bias, improving collaboration, and creating environments where individuals and organisations consistently perform at their best.
