Matellio vs Belitsoft: overview

Matellio

Matellio is a custom software development company founded in 2014 and headquartered in San Jose, California, with additional offices in Denver and the UK and engineering labs in India, totaling roughly 150–250 people. Its client base ranges from startups to Fortune 500 companies, giving procurement teams a broad reference spectrum to request against a specific company-size profile. Agentic AI is one part of a broader AI and cloud engineering practice, so buyers wanting a pure AI-agent specialist should confirm current agent-team allocation before contracting.

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.
