Infosys vs Sigma Software Group: overview
Infosys
Infosys was founded on July 2, 1981 by seven engineers in Pune before relocating its headquarters to Bengaluru, and has since grown to more than 328,000 employees serving enterprise clients globally. It runs dedicated practices in cloud, AI, data, and enterprise application services, and its scale gives it staffing depth for large digital transformation programs. Like the other Indian IT giants on this list, its size means engagements typically run through structured account management rather than direct engineer access.
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.
