Thomas McGuffie

Senior Associate

Tom is a founding member of the Markets Innovation Group (MIG), a group of lawyers, technologists and developers, who are focused on the creation of innovative solutions for clients that help them meet large-scale legal and regulatory challenges.

Tom has been featured by the Financial Times as a leading innovative practitioner in law.

Tom is a key member of the firm’s market-leading, cross-practice and multijurisdictional AI advisory practice; he works with some of the largest companies in the world on the safe deployment of AI in their businesses, as well as on broader legal and compliance digitisation projects. Tom has also played a leading role in the development and implementation of A&O Shearman’s own AI strategy, including assessment of third-party tools, governance and risk management.

Tom has been at the forefront of the development and delivery of A&O Shearman’s “Matrix” suite of products – most recently the generative AI powered “ContractMatrix” technology, which is streamlines contract drafting, analysis and negotiation. It was developed by the firm in partnership with Microsoft and Harvey. This was the first ever collaboration between a law firm and Microsoft to develop an AI tool. ContractMatrix is used extensively within A&O Shearman, as well as by clients.

Tom also leads MIG’s work on the digitalisation of our clients’ legal and operational processes, with his utilities being used daily by multiple large financial institutions.

At the FT Innovative Lawyers Awards (Europe) 2024, A&O Shearman won the award for the “Most innovative law firm in Europe”, which the FT noted was largely down to the firm’s pioneering approach to generative AI development and deployment, as well as the award for “Innovative in generative AI tools” for ContractMatrix.

Tom’s background is in OTC derivatives and he has experience across all major asset classes.
