EPAM Systems vs LeewayHertz: overview

EPAM Systems

EPAM Systems was founded in 1993, is headquartered in Newtown, Pennsylvania, and employs more than 61,000 people. It bought NEORIS and First Derivative in recent years to expand in Latin America and financial services. Its AI work sits inside a large software engineering business, so production AI usually arrives as part of a broader platform or product program. That suits enterprises with many products more than a company with one stalled pilot.

LeewayHertz

LeewayHertz was founded in 2007, is based in Gurugram, India, with a San Francisco office, and has around 200 people. The Hackett Group bought it in September 2024. It publishes a large volume of articles on AI development, and its own platform, ZBrain, is used as a base for client builds. Look past the content to production references before shortlisting it.
