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 designs and ships production-grade AI agents, AI-ready data platforms, and AI-native products, and its named client roster — Nike, Volkswagen, Autodesk, Sanofi, Galp, Glovo — is unusually well-documented for a boutique of its size. As a Portuguese EU entity, it offers full EU data residency alongside genuinely large-enterprise reference clients.
