EPAM Systems vs Sigma Software Group: overview
EPAM Systems
EPAM Systems was founded in 1993 and trades on the New York Stock Exchange, headquartered in Newtown, Pennsylvania, with more than 50,000 employees globally and a large Ukraine-based delivery workforce specifically. That's a different geographic bet than the India-anchored giants on this list: EPAM built its reputation on Central and Eastern European engineering talent rather than the traditional offshore-India model, giving it a distinct technical-culture reputation among the mega-scale vendors. Public-company scale still means formal enterprise sales cycles and account structures.
Sigma Software Group
Sigma Software Group's roughly 40-office footprint today is a long way from where it started: a single office in Kharkiv, opened in 2002 by five friends, four programmers and a lawyer. More than 2,100 professionals now work across named practices in aerospace, gaming, fintech, and automotive engineering, giving it a technical-consulting positioning closer to the mid-market global firms on this list than to a pure staffing vendor. Its post-2022 global expansion has genuinely diversified delivery risk away from any single country, though a buyer specifically wanting Ukraine-concentrated delivery should verify current team location directly.
