ML6 vs Smart Agent Technologies: 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.

Smart Agent Technologies

Smart Agent Technologies was founded in Vienna, Austria on April 15, 2008, and is headquartered there with roughly 57 employees. Its name and founding date predate the current agentic AI wave by well over a decade, giving it an unusually long operating history in the agent space specifically relative to most competitors on this list. As an Austrian EU entity, it offers a Central European jurisdiction distinct from the Poland-heavy cluster and Western European majors elsewhere in this roster.
