Wir arbeiten bereits seit einigen Jahren erfolgreich mit cronn zusammen. Auch in diesem Projekt haben sie unsere Anforderungen schnell verstanden. So konnten wir gemeinsam eine KI-basierte Lösung entwerfen und in Produktion bringen. Wir schätzen cronns Know-how in den Bereichen KI sowie Backend und sind mit der Umsetzung sehr zufrieden.
cronn has experience in designing and developing mission-critical software for various industries and partners.

Custom software is developed specifically for your unique business processes and requirements. Unlike standard software, which often requires compromises, custom software is a perfect fit with maximum efficiency and the flexibility to adapt to changing business needs.
While the initial cost of custom software may be higher, it offers better value for money in the long run. Customized solutions can be tailored to your exact needs, helping avoid license fees for unused features and reducing the need for costly adjustments later down the line.
The cost of custom software development varies widely and depends on multiple factors, such as the complexity of the project or specific requirements and features. We would gladly discuss your requirements, provide a cost estimate and find the right pricing model for your project: fixed price (work contract), agile fixed price or billing based on working hours. And the first consultation is on us! .
We start the development process with a thorough analysis of your requirements in order to fully understand your needs and goals. During development, we rely on regular meetings and feedback from you to ensure that the final product fully meets your expectations.
In one word: Yes! We ensure seamless integration with your existing systems and workflows while adding necessary solutions to your ecosystem.
