Tensorway vs B12 Consulting: 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.
B12 Consulting
B12 Consulting was founded in 2012 by a group of PhDs in Physics sharing a passion for complex problem solving, headquartered in Louvain-la-Neuve, Belgium with an additional Brussels presence, and roughly 35 FTE. It is a services company expert in artificial intelligence, data science, and custom software development, with a technical, research-adjacent culture reflecting its founders' academic backgrounds. As a Belgian EU entity, it offers full EU data residency at a compact, deeply technical headcount.
