Tech Mahindra vs Sigma Software Group: overview

Tech Mahindra

Tech Mahindra was formed on October 24, 1986 as a joint venture between Mahindra & Mahindra and BT Group, and has grown into a standalone IT services company of more than 148,000 employees headquartered in Pune. Telecom remains a visible strength given its BT Group origins, alongside broader enterprise digital transformation, cloud, and network services work. Being part of the larger Mahindra Group conglomerate gives it access to cross-industry relationships an independent firm wouldn't have.

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.
