Tensorway vs B12 Consulting: overview
Tensorway
Tensorway is the AI-focused unit of an established Alicante, Spain software development company with roughly 25 years in the market, spun out specifically to build agentic systems at a team size (50–249 people) closer to an agency than a global systems integrator. Its six-phase delivery methodology takes a client from assessment to a working agentic MVP in roughly a month, with compliance embedded rather than bolted on, and a discovery-first exploratory track lets smaller buyers de-risk before committing to a full engagement. That agency-scale headcount, paired with a decades-old parent company, is an unusual combination on this list.
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 an agency expert in artificial intelligence, data science, and custom software development, with a technical, research-adjacent culture reflecting its founders' academic backgrounds.
