EPAM Systems vs Belitsoft: overview
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.
Belitsoft
Belitsoft was founded in 2004 and is headquartered in Warsaw, Poland, with over 250 core employees and more than 400 developers, testers, and DevOps staff distributed across Poland, Latvia, and Georgia. The company expanded into cloud and generative AI development in 2024, layering AI solutions on top of an already-established web and mobile development and team augmentation business. That makes generative AI a genuinely recent addition rather than a rebrand of older services.
