Greg B Davies is a behavioural finance expert and leading authority on applied decision science, widely hired as a motivational speaker for his ability to transform complex psychological and financial theory into practical strategies for better thinking and performance. With more than two decades of experience working at the crossroads of psychology, finance and technology, Greg equips audiences with tools to make clearer, more confident decisions in high pressure and uncertain environments. His talks resonate with leaders, teams and organisations seeking to improve judgement, reduce bias and unlock more consistent results.
Greg’s early career laid the foundation for his distinctive approach to decision making. Entering the world of decision finance in the early 2000s, he became Director of Decision Technology, where he deepened his expertise in how psychology, economics and finance interact. He went on to join Barclays as Head of Behavioural Quant Finance, where he established the first behavioural finance team in global banking. There, he pioneered financial personality profiling and championed the use of behavioural data analytics, helping shift the industry’s focus from purely numerical models to a more human understanding of financial behaviour.
Building on this success, Greg founded Centapse, a firm dedicated to designing practical decision making solutions for businesses and their customers. He later became Head of Behavioural Finance at Oxford Risk, focusing on behavioural finance, risk profiling and financial decision processes. Alongside his corporate work, Greg has held influential board and advisory roles, including serving on the editorial board of the Journal of Behavioural and Experimental Finance and chairing the Savings Steering Group for the Financial Capability Strategy for the UK. He has lectured at the London School of Economics and Imperial College Business School, and has been a fellow at Saïd Business School and University College London. He is also a co-author of 'Behavioural Investment Management' and creator of widely respected online courses on behavioural investing and decision science.
As a motivational speaker, Greg stands out for his rare ability to blend rigorous science with engaging storytelling and real world relevance. He helps audiences recognise the hidden biases, emotional triggers and decision traps that influence performance, then provides clear frameworks to overcome them. Having advised major financial institutions and delivered keynotes around the world, he empowers people not just to think differently, but to act with greater clarity, discipline and confidence. His sessions leave delegates with practical mental tools they can apply immediately, making him a powerful catalyst for smarter decisions and stronger outcomes.
