Deviniti vs Belitsoft: overview

Deviniti

Deviniti is a Wrocław, Poland-based software company founded in 2004 by Piotr Dorosz and Jacek Machata, with roughly 260 employees across Europe and North America. Its established Atlassian Marketplace app and consulting business gives European procurement teams a checkable, independently reviewable track record beyond the vendor's self-reported claims. As a Polish company, it sits fully within EU jurisdiction, and its financial-sector origins mean it has existing compliance-aware delivery experience relevant to GDPR-sensitive agentic AI work.

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 experience in e-learning, healthcare, and fintech gives European buyers in those sectors a directly comparable reference base. Its Poland and Latvia offices sit within the EU; its Georgia office sits outside EU jurisdiction, worth confirming per-project data residency.
