EPAM Systems vs Sigma Software Group: overview

EPAM Systems

EPAM Systems trades on the New York Stock Exchange, which sets it apart from every other company reviewed here: it's a publicly audited, multi-billion-dollar corporation headquartered in Newtown, Pennsylvania, founded in 1993, with Ukraine long standing as one of its largest delivery geographies alongside Belarus, Poland, and India. It has consistently ranked among the top IT employers in Ukraine by revenue, and its scale gives it engineering and consulting practices spanning cloud, data, AI, and enterprise platform work that most single-country firms cannot replicate. As with GlobalLogic, the trade-off is similar: EPAM uses Ukraine as one of several delivery hubs rather than operating as a Ukraine-founded or Ukraine-owned business, and its size means engagements typically run through formal enterprise sales and account-management processes.

Sigma Software Group

Five friends started Sigma Software Group in Kharkiv in 2002; the company now runs roughly 40 offices across 19 countries with more than 2,100 professionals. It runs practices across gaming, aerospace, fintech, and automotive engineering, positioning itself as a technology consulting and product development partner rather than a pure staffing vendor. The company's own relocation and expansion since the 2022 full-scale invasion has moved a meaningful share of delivery capacity outside Ukraine, which buyers who specifically want Ukraine-based delivery should confirm directly.
