Because we believe the best teams are built on merit.

AI at Qonto

We see AI as a catalyst for our success. We always choose thinking over routine. That is why AI is already deeply embedded in how we work – not as a trend, but as a way to raise the bar for the entrepreneurs who count on us. We grant our Qontoers unlimited access to the best AI tools on the market – Claude Code, Cursor, Copilot, Dust, and Notion AI. We want people who experiment without waiting for permission, who push AI beyond the obvious, who know when to trust it and, more importantly, when to question it. Already pushing AI limits? You'll fit right in.
