Endava vs Twistag: overview

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.

Twistag

Twistag is a Lisbon, Portugal-based team of senior AI engineers, designers, and strategists founded in 2016, with 11–50 employees. 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.
