Neurons Lab vs Endava: overview

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.

Endava

Endava was founded in 2000 and is headquartered in London, UK, with over 10,000 employees across 26 locations. It has embedded OpenAI's AI agents directly into its own software delivery workflow, branded as DavaFlow, making it one of the few firms on this list that has publicly documented using agentic AI to redesign its own internal delivery process, not just sell it to clients. As a UK-headquartered, NYSE-listed company, it offers public financial disclosure but sits outside EU jurisdiction post-Brexit for its own corporate entity.
