Persistent Systems vs Sigma Software Group: overview
Persistent Systems
Persistent Systems was founded in Pune, India in 1990 and has grown to nearly 24,000 employees, occupying a middle tier between the true mega-giants on this list and the mid-market global players: large enough for serious enterprise programs, small enough that account relationships are less layered. Its practice covers software engineering, data, AI, and cloud services for enterprise clients, with a particular focus on technology and life sciences sectors. Its scale sits well below Accenture or TCS but comfortably above most of the boutique firms reviewed here.
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.
