EPAM Systems vs LeewayHertz: overview

EPAM Systems

EPAM Systems was founded in 1993 and is headquartered in Newtown, Pennsylvania, with over 61,200 employees at the end of 2025. Acquisitions shaped the recent mix: NEORIS (2024) for Latin America and Iberia, and First Derivative (completed December 2024) for financial-services data. Management targets more than $600 million of AI-native revenue in 2026, after reporting over $105 million in Q4 2025. Its AI/Run tooling and Agentic QA product support large engineering programs more than single-workflow pilots.

LeewayHertz

LeewayHertz was founded in 2007 in Gurugram, India, and keeps a U.S. office in San Francisco, with roughly 150–300 staff. The Hackett Group bought it in September 2024 for $7.8 million, per Hackett's SEC filings, and the two formed a joint venture around its ZBrain enterprise AI platform. It publishes a very large volume of AI content, which inflates its visibility relative to its verifiable delivery record. ZBrain is model-agnostic across the major LLM providers.
