What is 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.

ML6 works primarily with clients in Manufacturing, Financial Services, Retail & E-commerce, Technology & SaaS sectors. Its primary differentiator is: A 100% EU office footprint (Ghent, Amsterdam, Berlin, Munich) with zero non-EU locations — the cleanest data-residency story among the boutiques on this list.
