Our Philosophy

andagon – the name stands for quality and excellent service. Our company location is Germany and it is our mission to provide “quality made in Germany” with our products and services world-wide. Our customers are able to ensure the quality of their systems and therefore the lasting success of their business with the help of our QA products and apps as a service. The key to the continuous improvement of this concern is innovation. We operate in a fast moving world. Even in a technological world in which the pace continues to increase, quality must not be neglected in favour of production speed and mass Quality is important, in no matter which industry.

We adapt our economic methods to the circumstances in order to remain one step ahead of progress. We put bold and energetic new concepts to the test, at the same time carefully weighing up the potential risks.


Founding of andagon GmbH in Königsdorf
Stefan Gogoll founds andagon GmbH, its focus being IT development and consulting
First load and performance testing
andagon carries out first load and performance testing for a DAX-listed company.
Cross browser testing commissioned by a customer.
First cross browser testing is carried out and designed for a customer.
Birth of andagon aqua
andagon’s customers work with completely different test tools, which is why there is a lack of transparency. For this reason, andagon developed an internal tool supporting our customers’ QA consulting. For the first time, tests on different tools can be managed, results collected and clearly represented for customers on a single platform.
„aqua goes public“
aqua is fully developed and can be launched. Following a tendering process, the first customer decides on aqua – independently from a consulting project realised by andagon. Further customers rapidly follow suit.

New location in Munich
andagon continues to grow and move into another location. As of now, we are also represented at the Design Offices in Munich on Luise-Ullrich-Straße.
andagon in the heart of Cologne
After my career as a cycling professional, I took the first steps in self-employment in 1999 during my computer science studies. At that time, I was able to develop and program the first track and trace system for Deutsche Post AG. After successful completion, I implemented the test automation in IT at T-Mobile. This led to the foundation of andagon GmbH in 2001. In both projects, the added value for high-quality solutions became immediately apparent. This joy in quality drives me every day to deliver the decisive difference for our customers with our teams. Since the first day, the topics test automation and quality assurance in IT are the core competencies of andagon. With our constant growth path, we are able to improve more and more company quality transparently - not just in IT.
