Twistag vs OpenKit: 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. Its senior-only positioning means no client work gets handed to junior staff.

OpenKit

OpenKit is a UK-based AI and software development agency founded in 2019, headquartered in Durham with additional presence in London and Cambridge, and a very small team of just 2–10 people. Despite its size, it holds ISO 27001 and ISO 9001 certifications and is Cyber Essentials certified — independently verifiable security credentials unusual for a micro-agency, serving legal, healthcare, education, financial services, and manufacturing SMEs and mid-market businesses across the UK.
