LONDON, BRUSSELS Keystone Strategy LLC (Keystone), a consultancy to top technology companies, government agencies and global law firms on strategy, economics, technology, and competition, today announced that Stefan Hunt would join as Partner and Head of Keystone Advanced Technology Services (K.ATS) in Europe, on 24 January 2023.

Dr Hunt is an advanced analytics leader and economist with 20 years of experience using rigorous analytics in competition, regulation and business strategy. Stefan will work closely with Andrea Coscelli and Cristina Caffarra – the joint heads of Europe, leading Keystone’s European expansion – and Rohit Chatterjee, the global head of K.ATS.

Keystone was founded by Greg Richards and Professor Marco Iansiti in 2003 and is one of the world’s most prominent advisors to the technology sector, building deep expertise by handling high-profile cases with a specific focus on the digital economy. Keystone’s affiliates are all top academic experts on digital transformation, innovation, platform economics, computer science, strategic management, and ecosystems, supported by 150 professionals across its US and London offices.

Dr Hunt spent nearly five years at the UK’s Competition and Markets Authority (CMA), creating the world-leading data and technology function among competition agencies, now a team of over 50 specialists. Before that, he founded data science, behavioural economics and rigorous micro econometric analysis capabilities at the UK’s Financial Conduct Authority. He has a PhD in Economics from Harvard University.

Stefan Hunt said, “Keystone’s mix of economics, strategy and technology disciplines gives it an unrivalled offering in the digital and technology space. The future of legal advisory work – for antitrust, IP, risk and regulation or tax – and the future of business strategy is about harnessing the power of integrating these disciplines. I’ve already worked closely with Andrea, who shared the vision of pushing the integration of data and technology capability into competition at the CMA. Working with him, Cristina Caffarra and the rest of the Keystone team, we aim to provide informed advice on antitrust and strategy questions grounded in technological expertise.”

Cristina Caffarra said, “Economists often have limited insights to offer in complex digital cases without support from data and computer scientists with a deep understanding of the technology. Stefan built a best-in-class data and technology function that delivered for key CMA cases. Other global competition agencies have recognised this and engaged with Stefan and the CMA to develop their digital capabilities. I am looking forward to working with him.”

Rohit Chatterjee said, “Stefan brings a wealth of technology and analytics experience from his time at the CMA and the UK’s Financial Conduct Authority and, with his economics background, will fit well into Keystone. I’m looking forward to building the global K.ATS function with him.”

The new Keystone office in London will serve as the European headquarters for the firm. Although Keystone has served major technology clients in the European region for the last decade, the expanding team in London will help the firm play a key role in future competition, regulatory, and litigation matters while attracting more talent to the business.
