Our hearts beat for software craftsmanship, our customers, and our team! Since 2013 we have been successfully implementing software projects in Bonn, Hamburg and Białystok (PL). Always in our toolbox: Java, open-source technologies, and agility. In addition, customer orientation and quality are particularly important to us – and, of course, the fun of working together.
Requirements often change in the course of a project! Thanks to our agile methods we are prepared for this. Continuous adaptation to new requirements allows us to react quickly to changes, always offering our customers the best solution. This speeds up software development and reduces costs.
Software testing tells no lies, provides security in the event of changes and is the basis for continuous integration. A good test base increases the quality of the code as well as the end product and saves effort in debugging, refactoring, and maintenance. This enables faster and higher-quality development cycles. And our developers have more time to devote to the essentials: good code!
The status and quality of a software project requires constant checks, which results in many repetitive tasks. Manually, this could quickly become painful. That is why we rely on a smooth, automated connection between development, version management, testing and deployment to production.
Programming languages were invented to write software in a manner intelligible to humans, then use it to solve complex problems. Therefore, source code should remain understandable. That is why we write clean code that is easy to read, understand, and maintain.
Some words by our CEO
Good code with good people - that's why I founded cronn. cronn is more than just a software company for me. It is a place where the joy of good code is the focus. Both for our team, which develops it, and for the customer, who uses the software in the end.
— Jobst Eßmeyer, CEO
A handful of people has, over time, grown into more than 150 dedicated cronners, all taking customer projects over the finish line and constantly making cronn better and better! Matters of software development, testing, and business analysis are faced head-on by our colorful teams at our 3 locations in Germany and Poland. And let us not forget the front office, HR, sales, and marketing, all keeping the wheels turning.Meet our team

cronn has been around since 2013. It all started with software developer Jobst, who wanted to develop high-quality, user-friendly software, all while using the latest open-source techs, agile methodologies, a test-driven approach, and still be fun to work on. Or, as he puts it himself: He wanted to write good code with good people. The best way to implement his ideas was in his own company, so he founded one.
Since then, more than 150 people have joined us at three locations in two countries. The original spirit still permeates our corridors and offices today. Be it in project meetings, Scrum events or over our end-of-week Friday beers, at company runs or our legendary cronn celebrations: Whatever we do, we do together and with pleasure. And often right in the middle of it all: founder Jobst..
