Vstorm vs Emerline: overview

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.

Emerline

Emerline is an IT services and consulting agency founded in 2011, with LinkedIn listing its headquarters in Miami, Florida (other sources cite Mountain View, California), and roughly 500–520 employees across Europe, North America, and Asia. It has operated as part of LeverX Group since 2011, helping startups and established businesses build software products, with agentic AI as a newer addition to that practice — the LeverX Group ownership structure is a material fact buyers should confirm during due diligence.
