Twistag is an AI, data and software agency in Lisbon, Portugal. We design and ship production AI agents, AI-ready data platforms and AI-native products. We work with start-ups, scale-ups and enterprises across Europe, the UK and the US. Founded in 2016.
Twistag is 25+ senior engineers, designers and AI specialists. Most have eight or more years in their discipline. A typical engagement runs with one or two forward-deployed engineers. A forward-deployed engineer works inside your systems and your team, not from a separate agency backlog, with AI tooling doing the heavy lifting alongside them. Larger programmes scale to a squad of 3 to 8. The people you meet are the people who build.
Since day one. Data integrations, BI tools, recommendation engines and machine learning have been part of what we do since inception. Production LLM and agentic AI work since 2023. More than thirty AI agents in production and counting, from internal workflow automation to customer-facing features.
Financial services, retail, e-commerce, hospitality, healthcare, manufacturing and media. We have shipped for Autodesk, DHL, VW, Bangkok Bank, Ruinart and Glovo, alongside dozens of European scale-ups.
Twistag is ISO 27001 compliant. We are an AWS Partner and an Anthropic Partner, and a member of the Data Science Portuguese Association. We were listed in the Deloitte Technology Fast 500 EMEA in 2023 and 2024. Our Clutch rating is 4.9 across 13 client reviews.
Twistag is based in Lisbon, Portugal. We work remote-first with clients across Europe, the UK and the United States, and we travel for kickoffs and key milestones. Lisbon sits inside the UK and EU working day and overlaps the US morning.
