Who we are

We are ZWEIDENKER, a software agency and an international team of creative specialists. We develop mobile IOS and Android apps, including Flinkster and Call a Bike, as well as individual software. In order to remain flexible and to be able to act quickly, we work with flat hierarchies and agile processes.
In our beautiful office in Cologne we develop on the latest hardware. Since continuous development is important to us, we meet regularly and exchange ideas, optimize our processes and upskill our team members. Your personal development is also important to us, that is why we support you wherever we can.
In addition, we regularly enjoy our balcony with our nice colleagues barbecuing or spending a relaxed time on our annual team trip.

Opinions of our team

„Je trouve que travailler à IID est très agréable grâce à l'atmosphère détendue et la bonne humeur qui y règne. Le bureau est très spacieux, aéré et calme. Nous partageons régulièrement nos connaissances ce qui m'a permis d'apprendre beaucoup de choses et de grandement m'améliorer en programmation.”

(„I like working at IID - because of the good and relaxed atmosphere. The office itself is spacious and quiet. We regularly share our knowledge and experience - this has taught me a lot and has improved my programming

Guillaume | Android und Backend Developer

“As a software developer at Zweidenker, I like working independently and being able to contribute my ideas. We use current mobile technologies like Swift or Kotlin and focus on quality. Working in a small team means that the communication is easy and quick - all this in a beautiful office with the best location in Cologne.
We also have a spacious balcony where we enjoy barbecues in the summer.
