N-iX vs Sigma Software Group: overview
N-iX
N-iX was founded in Lviv in 2002 and has grown to more than 2,000 professionals spread across eight countries, Poland, Ukraine, Sweden, Bulgaria, Malta, the UK, the US, and Colombia, giving it a genuine UK presence rather than a purely offshore sales relationship. Its practice spans custom software, cloud, and data engineering for enterprise clients, with the multi-country footprint offering real delivery-risk diversification a single-country vendor can't match. That spread is a real advantage for a UK buyer wary of concentrating delivery risk in one location.
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.
