Twistag vs Rootstrap: overview

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 an agency of its size.
