ML6 vs Belitsoft: overview

ML6

ML6 is an AI engineering company founded in 2013 by Nicolas Deruytter and Michael Lemmer, headquartered in Ghent, Belgium, with roughly 178 employees across offices exclusively in Ghent, Amsterdam, Berlin, and Munich. Unlike most firms on this list, it operates with zero non-EU offices — every delivery location is inside the EU, which materially simplifies data-residency and cross-border transfer questions for European procurement teams. Its positioning as "Enterprise Superintelligence" reflects a broader AI engineering practice, of which agentic AI is one growing part.

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.
