N-iX vs Sigma Software Group: overview
N-iX
N-iX was founded in Lviv, Ukraine in 2002, growing out of work building product applications for Novell's Linux platform before Novell acquired that technology and the founding team stayed together as an independent firm. It now reports more than 2,000 engineers and a legal headquarters in Malta, delivering software engineering, cloud, AI, and data analytics services alongside more than 60 completed IoT and embedded projects covering firmware development, connected device engineering, and industrial IoT. That scale gives it delivery capacity few boutique firmware teams can match, though embedded and firmware work is one practice inside a much larger enterprise software portfolio rather than the firm's primary identity.
Sigma Software Group
Sigma Software Group was founded in Kharkiv, Ukraine in 2002 by five friends and now employs more than 1,100 people across Ukraine, Sweden, Poland, and the United States. In 2006 the Swedish IT conglomerate Sigma Group acquired a 60% stake in the company, an ownership structure that has held since; the remaining 40% stays with the original Ukrainian founders. Its embedded and IoT services cover application development, firmware, middleware, device drivers, and human-machine interfaces, delivered as one practice within a much larger portfolio spanning gaming, aviation, and telecom software.
