Vstorm vs Smart Agent Technologies: overview

Vstorm

Vstorm is a Wrocław, Poland-based boutique founded in October 2017 by CEO Antoni Kozelski and VP Bartosz Gonczarek, with a compact team of 11–50 people, operating fully within the EU 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, with a public commitment to AGENTS.md documentation on every project. As a Polish company, it falls squarely under GDPR without any cross-border transfer questions for EU clients, and its founders speak and publish regularly on EU AI Act readiness specifically.

Smart Agent Technologies

Smart Agent Technologies was founded in Vienna, Austria on April 15, 2008, and is headquartered there with roughly 57 employees. Its name and founding date predate the current agentic AI wave by well over a decade, giving it an unusually long operating history in the agent space specifically relative to most competitors on this list. As an Austrian EU entity, it offers a Central European jurisdiction distinct from the Poland-heavy cluster and Western European majors elsewhere in this roster.
