Sigma Software Group vs Belitsoft: overview
Sigma Software Group
Sigma Software Group was founded in 2002 and is headquartered in Stockholm, Sweden, with more than 2,100 professionals across 40 offices in 19 countries and over two decades of continuous operating history. Its AI practice spans AI-assisted development through agentic task execution in well-bounded modules, emphasizing quality and predictability in real production codebases, and it contributes to industry initiatives on agent-based interactions in programmatic advertising. Its wide European office footprint is an asset for procurement teams weighing GDPR-aligned data residency, though its agentic AI work is scoped more narrowly (well-bounded modules) than some competitors' full multi-agent architecture offerings.
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.
