Tensorway vs B12 Consulting: overview
Tensorway
Headquartered in Alicante, Spain since 2019, Tensorway's AI-agent team inherits an EU legal entity and EU data residency by default — not retrofitted for European buyers after the fact — from a parent software company with roughly twenty-five years of continuous operation. Compliance (GDPR, HIPAA, ISO 27001) is named as an explicit phase in its six-phase delivery methodology rather than treated as an afterthought, and its lightweight, API-first architecture is built to plug into a client's existing systems instead of forcing a platform overhaul. Operating fully within EU jurisdiction lets it sidestep 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.
