Help build sovereign AI.
twenty5ai builds Quinta — the on-premise AI platform that lets organizations run AI on their own hardware. We’re looking for people who love technology and take control seriously. Not a single byte leaves the building — ours included.
Substance, not hype
We build a product that delivers real control over AI — measurable, verifiable, without buzzwords.
European & sovereign
Data sovereignty isn't marketing here — it's the core of the product. That shapes how we work.
Remote-first
Work where you're most productive. We meet at the customer and regularly as a team.
Close to the customer
We solve real problems of regulated industries — at the source, not from a distance.
