ITRex Group vs EPAM Systems: overview
ITRex Group
ITRex has been based in Southern California since 2009, and public headcount estimates range from around 221 up to over 250 employees across three continents. The agency pairs generative AI and machine learning with data analytics and cloud computing rather than offering AI in isolation, which means clients get a partner who can handle the data plumbing a generative AI system needs before the model itself gets built. That broader scope costs some depth relative to generative-AI-only specialists but avoids a common integration bottleneck.
EPAM Systems
EPAM Systems dates to 1993, co-founded 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, a scale category no other agency on this list approaches. Generative AI transformation engineering is a marketed practice area, but at this size it functions as part of a much larger digital engineering business rather than a standalone specialty.
