ML6 vs Sopra Steria: 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.

Sopra Steria

Sopra Steria Group SA was founded in 1968 and is headquartered in Paris, France, with approximately 58,000 employees, positioning itself as a European tech leader in consulting, digital services, and software development. In June 2026 it published the first European study dedicated to agentic commerce, based on a survey of 8,400 consumers across eight countries, estimating €310 billion in transactions could be assisted by AI agents across Europe within a decade — giving it a research-driven credibility angle among the larger European systems integrators on this list.
