Over the past 30 years, Mayer Brown’s outsourcing practice has represented leading companies as customers in over 400 information technology outsourcing (ITO), business process outsourcing (BPO) and other outsourcing transactions with an aggregate market value exceeding $250 billion. This experience translates into superior skill at getting these deals done and current market knowledge that allows us to bring solutions that work and secure high-value commitments, options and incentives. Chambers USA has given us its top ranking in the IT/Outsourcing category for 19 consecutive years and Legal 500 has awarded us its top ranking in the US IT/Outsourcing for as long as the category has existed.

As outsourcing transactions have expanded to leverage cloud, XaaS, AI, RPA and other technologies, we have expanded our areas of expertise. Our role in the industry has been as thought leaders, developing contracting concepts to help customers secure commitments to value for each generation of technology. We have incorporated what we have learned into tools, templates, training, best practices and solutions that work in a variety of circumstances. As a result, we can deliver better outsourcing deals faster.
