Stefan Hunt

Stefan is a Partner in the London office and Head of Keystone’s Advanced Technology Services (K.ATS) in Europe. Stefan has over 25 years of experience in using cutting-edge analytics to deliver impact for businesses. He has a background in economics and strategy as well as technology and works across Keystone’s practice areas.

Prior to joining Keystone, Stefan was the Chief Data and Technology Insight Officer at the UK Competition and Markets Authority (CMA). He created and led a team of technologists – including behavioural scientists – that grew to nearly 60 people and became the world-leading unit of its kind. Stefan worked on digital regulation and was actively involved in all the CMA’s major digital cases, from mergers and acquisitions to market studies and investigations, to antitrust cases. He created the CMA’s initiatives on algorithms and online choice architecture that have had significant impact on competition cases and have been influential globally.

Stefan was the founder and head of the behavioural economics and data science unit at the UK Financial Conduct Authority, and prior to that he was a strategy consultant with Marakon Associates and Prudential Corporation Asia, working on a full range of strategy projects including acquisitions and divestitures.

He has a PhD in economics from Harvard University, a master’s in experimental psychology and mathematics from the University of Cambridge, and he is an Honorary Professor in economics at the University of Nottingham.

Outside of work, Stefan enjoys running after his young daughters, biking, swimming and the self-flagellation of supporting Tottenham Hotspur (hoping, eternally, that this last part is redundant by the time you read this).
