ELEKS vs Sigma Software Group: overview
ELEKS
ELEKS opened its doors in Lviv in 1991, a year before Ukraine itself became independent, which makes it the longest-running company on this list by a wide margin. More than 2,000 engineers now work across custom product development and enterprise system modernization, with particular depth in healthcare, insurance, and financial technology. That much institutional history gives ELEKS mature delivery processes and a deep senior bench, though its public materials lean on longevity more than on any single narrow technical specialty.
Sigma Software Group
Five friends, four programmers and a lawyer, started Sigma Software Group in Kharkiv in 2002. More than two decades later the company runs roughly 40 offices across 19 countries with over 2,100 engineers, building software for aerospace, gaming, fintech, and automotive clients under named domain practices rather than one generic development service. Its post-2022 expansion has shifted a real share of delivery capacity outside Ukraine, so a buyer who specifically wants Ukraine-based engineers should confirm current team location.
