Tensorway vs Vstorm: 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.

Vstorm

Vstorm is a Wrocław, Poland-based boutique agency founded in October 2017 by CEO Antoni Kozelski and VP Bartosz Gonczarek, with a compact team of 11–50 people, operating exclusively as an agentic AI engineering consultancy. It was the first AI consultancy accepted into the Agentic AI Foundation (AAIF) and publishes its own TriStorm delivery framework. As an 11–50 person shop, it sits at the smaller end of this list, giving buyers direct access to the same senior engineers who scope the work.
