Andersen vs Endava: overview

Andersen

Andersen is a European IT company founded in 2007 and headquartered in Warsaw, Poland, with more than 3,700 experts across 16+ global locations, the majority of them European — Germany, the UK, Lithuania, Hungary, and Cyprus, alongside Kazakhstan, Georgia, Azerbaijan, and the UAE outside the continent. It embeds AI tooling into the software development lifecycle and builds conversational agents integrated with CRM, helpdesk, and messaging platforms, positioning itself as a broad staff-augmentation and delivery vendor rather than an AI-only boutique.

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.
