Sigma Software Group vs Softengi: overview

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.

Softengi

Three decades of general custom development and consulting sit behind Softengi's current positioning, dating back to a 1995 founding in Kyiv, part of the earlier wave of Ukrainian software companies to launch after independence, with a timezone that overlaps UK working hours comfortably. Public data on its current team size and specialization is thinner than for the more heavily marketed firms on this list, so buyers should verify current capacity directly. Its positioning is general enterprise software development rather than a named vertical or technical niche.
