IBM Consulting vs EPAM Systems: overview

IBM Consulting

IBM Consulting's history runs back to 1991, and it operates today out of Armonk, New York, with a global headcount near 160,000. The 2021 rebrand from IBM Global Business Services signaled a shift in focus, and its AI work now leans heavily on IBM's own watsonx platform alongside decades of enterprise client relationships. For a company already standardized on IBM infrastructure, that's a genuine advantage; for one that isn't, it's a real limitation worth weighing before a shortlist gets built.

EPAM Systems

EPAM Systems was co-founded in 1993 in New Jersey and Minsk by Arkadiy Dobkin and Leo Lozner, and it's been an S&P 500 constituent on the NYSE since 2012. By the end of 2025 it employed roughly 62,850 people across more than 55 countries. Its AI advisory and transformation engineering work runs as a company-wide practice, and what separates it from a typical Big Four strategy firm is that its advisors sit directly alongside the technical staff who build what gets recommended, rather than handing off to a separate delivery team.
