Sigma Software Group vs Apriorit: 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.
Apriorit
Kernel drivers, virtualization layers, and reverse engineering, the low-level systems work sitting underneath the applications most general outsourcing vendors on this UK-facing list actually build, are what Apriorit has specialized in since its 2002 founding in Kharkiv. That's a genuinely rare skill set, and it's exactly why a UK security vendor or infrastructure company needing this specific work should look here rather than toward a generalist. It is simply the wrong fit for a buyer who needs a standard business application built.
