IBM Consulting vs EPAM Systems: overview

IBM Consulting

IBM Consulting's roots go back to 1991, and it operates out of Armonk, New York with a global headcount around 160,000. Rebranded in 2021 from IBM Global Business Services, its AI advisory work is built around IBM's own watsonx platform and decades of enterprise account relationships. For a buyer already running IBM infrastructure, that tie-in is a real advantage; for a buyer who isn't, it's a real constraint worth weighing before shortlisting.

EPAM Systems

EPAM Systems was co-founded in 1993 in New Jersey and Minsk by Arkadiy Dobkin and Leo Lozner, and has traded on the NYSE as an S&P 500 constituent since 2012. It employed roughly 62,850 people across more than 55 countries at the end of 2025. AI advisory and transformation engineering runs as a marketed practice across the firm, distinguished from pure Big Four strategy firms by EPAM's engineering-heavy delivery model: advisors sit alongside the technical staff who actually build what gets recommended.
