Vstorm vs Neurons Lab: 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.

Neurons Lab

Neurons Lab is a London-headquartered AI-exclusive consultancy founded in 2019, with 51–200 employees, that has delivered agentic and broader AI transformation projects to more than 100 clients across Europe and the UK, per the company. Its AWS Advanced Tier partner status, with named competencies in Generative AI and Financial Services, gives buyers an independently checkable credential, and its reported client roster (HSBC, Visa, AXA) points to genuine regulated-industry delivery experience. As a UK-headquartered firm, it sits outside strict EU jurisdiction post-Brexit but maintains UK GDPR alignment and serves EU clients directly.
