Our team is 104 cronners strong and includes highly qualified analysts, designers and developers as well as DevOps and test automation engineers.

cronn work closely with their clients to develop individual software solutions: starting with specialized technical conception, through implementation and commissioning up to maintenance and support; we go from connecting databases, through backends with business logic up to accessible advertising spaces and apps for iOS and Android. Our backends are built exclusively using Java and Kotlin, while our frontends rely on TypeScript, Kotlin or Swift.

We develop with passion, love Clean Code, test-driven development, agile processes, Continuous Integration and delivery.
