LeewayHertz vs EPAM Systems: overview

LeewayHertz

LeewayHertz has operated from San Francisco since 2007, though its ownership changed in September 2024 when The Hackett Group acquired the company. That's relevant to anyone evaluating long-term strategic direction, since the agency now answers to a larger consulting parent. Public employee counts have also shifted, from roughly 300 in earlier reporting to about 182 by mid-2026, worth confirming directly given the volume of content marketing the agency publishes relative to its actual team size.

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. AI transformation engineering is a marketed practice area, but at this size it functions as part of a much larger digital engineering and cloud transformation business rather than a standalone specialty.
