Mark Lewis

Senior consultant

For over 35 years, and recognised as one of the UK’s leading practitioners, Mark has specialised in transactions for, and advice on, the acquisition and use of IT and business process products, systems, and services, including all forms of outsourcing, managed services and cloud computing transactions, many of them mission- or business-critical.

Mark represents customer- and supply-side organisation in all forms of IT, business process and operations sourcing and outsourcing transactions.

He advises on the deployment of advanced technologies and business models, including AI, cloud computing, digitalisation, and cyber-related issues.

Much of his representation is in the financial services sector. His clients have included global, FTSE and challenger financial services firms and fintech providers across the banking, insurance and asset management industries.

His other clients have included governments, international organisations, and corporates in the utilities, media, business services, manufacturing, mobile telecommunications, security and aviation sectors.

In all the sectors he covers, Mark has represented a broad range of IT and business process service providers, from the largest globally to early-stage niche technology companies. Representing both customers and providers – which is rare in the market - gives him an unrivalled perspective of both sides in any IT and outsourcing transaction. This enables him to help clients on both sides secure effective and long-lasting commercial relationships.

Mark is a Visiting Professor in Practice in the Law School of The London School of Economics and Political Science, where he has lectured on AI and machine learning, cyber security and resilience, cloud computing, and legal technologies.
