Tensorway vs ML6: overview

Tensorway

Tensorway is the AI-focused unit of an established software development company headquartered in Alicante, Spain, with roughly 25 years in the market, giving it an EU legal entity and EU data residency by default rather than as a retrofitted option. Its six-phase delivery methodology names compliance — GDPR, HIPAA, and ISO 27001 — as an explicit phase rather than an afterthought, and its lightweight, API-first architecture is designed to connect into a client's existing systems without a platform overhaul. As a Spanish company operating fully within EU jurisdiction, it avoids the cross-border data-transfer questions that non-EU vendors on this list have to answer.

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.
