Sigma Software Group vs Apriorit: overview
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.
Apriorit
Most software development companies write applications; Apriorit writes the kind of low-level code that sits underneath them, kernel drivers, virtualization layers, and reverse-engineering work, a specialization built up since its 2002 founding in Kharkiv. That skill set is genuinely rarer than general web development, and it's what makes Apriorit a strong fit for security vendors and infrastructure companies specifically. The team stays smaller and more technically concentrated than the enterprise-scale firms on this list, which suits deep systems work better than very large parallel programs.
