ELEKS vs Sigma Software Group: overview
ELEKS
Lviv sits one to two hours ahead of UK time depending on the season, close enough for a full overlapping working day, which matters for ELEKS specifically given the company has been running continuously from there since 1991, a year before Ukraine declared independence. That three-and-a-half-decade history has produced a deep healthcare, insurance, and fintech track record and a stable, senior-heavy delivery process. Its public positioning leans on decades of history more than any single sharp technical specialty.
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.
