Vstorm vs Innowise: 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.

Innowise

Innowise is an international full-cycle software development company founded in 2007 and headquartered in Warsaw, Poland, bringing together more than 3,500 IT professionals across a broad portfolio of custom software, and more recently agentic AI services. Its scale gives it capacity for large, multi-team European programs, though its origins are as a generalist software house rather than an agentic-AI-first specialist. As a Polish EU entity, it sits fully within EU jurisdiction for its headquarters operations.
