GlobalLogic vs Sigma Software Group: overview

GlobalLogic

Hitachi's roughly $9.6 billion acquisition of GlobalLogic in 2021 folded a Santa Clara-founded, Ukraine-heavy engineering workforce into a Japanese industrial conglomerate's supply chain. Founded in 2000, the company now runs roughly 5,700 engineers, out of a larger global headcount, from Kyiv, Kharkiv, Lviv, and Mykolaiv, cities that all sit close enough to UK time for genuine working-day overlap. Corporate structure under a large conglomerate does mean less direct founder-level access than a UK-facing boutique on this list.

Sigma Software Group

Five friends founded Sigma Software Group in Kharkiv in 2002; the company has since scaled to more than 2,100 professionals across roughly 40 offices worldwide, with its post-2022 expansion adding real Western European delivery presence alongside its original Ukrainian base. Named practices in aerospace, gaming, fintech, and automotive engineering give it a technical-consulting positioning UK buyers evaluating a specific vertical need can lean on. That same expansion means a buyer specifically wanting Ukraine-concentrated delivery should verify current team location directly.
