AI at Qonto

We see AI as a catalyst for our success.
We always choose thinking over routine. That's 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. That is why 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.

⚙️ Our stack & practices

Our app is 100% Swift based, built on MVP & clean Architecture principles with modular design (35+ independent modules can already be built and rendered separately). We leverage the Coordinator pattern to ensure a robust and scalable codebase.

We are committed to a modern UI: all new screens are built with SwiftUI in MVVM, and we have already migrated 80+ screens , with modern async/await patterns to follow modern standards). We also use Tuist for project generation and Tuist cache to decrease build time.

Our CI/CD pipeline includes GitHub Actions, Bitrise, Firebase Test Lab, Sonar, and Fastlane for comprehensive automation.

We prioritize technical excellence by:
• Adhering to Clean Code / SOLID principles
• Investing heavily in stability & tests: 30000+ unit tests and 450+ Snapshot tests
• Adopting a module-based architecture with 32 reusable modules and a centralized design system ensuring faster builds, clear ownership, and safer iterations.
• Using SwiftyMocky for comprehensive mock generation and protocol-oriented testing
• Latest LLMs are used heavily to increase our ability to add meaningful code and rely on AI when necessary.
