N-iX vs Belitsoft: overview

N-iX

N-iX is a software engineering services company founded in 2002, with headquarters reported as Lviv, Ukraine (also listing a Valletta, Malta corporate address), and more than 2,400 professionals across Europe, the Americas, and APAC. Its cloud, data, embedded, IoT, and AI/ML services span multiple technology domains, so procurement teams already contracting N-iX for one of those can typically add agentic AI as a scope amendment rather than issuing a fresh RFP. Its scale is an asset for enterprise programs but means agent work competes internally with many other active service lines for senior staffing priority.

Belitsoft

Belitsoft is a custom software development company founded in 2004 with headquarters in Warsaw, Poland and delivery teams distributed across Poland, Latvia, and Georgia, totaling roughly 130–400 developers, testers, and other specialists depending on the source. Its existing vertical contract history in e-learning, healthcare, and fintech gives procurement teams in those sectors a directly comparable reference base to request. Reported employee counts vary significantly by source, so buyers should confirm current team size directly during due diligence before finalizing a large program.
