Our success stories

Accelerated Development and Continuous Innovation

Together with the Comsysto Reply team, as the Product Owner of the Used Car Platform, I was able to develop a modern and flexible sales platform which we brought to go-live within less than 12 months. Thanks to the extensive technical and methodological competence of the Comsysto Reply team, the Used Car Platform is continuously being developed further and will serve us at AUDI AG as the central platform for B2B sales of all commercial and used vehicles in the future. Throughout our long-term collaboration, the team provided a wealth of creative suggestions and efficient solutions – both for technical challenges and process optimizations. Based on my project experience, I would recommend Comsysto Reply to any of my colleagues as a development partner!

Seamless Modernization of Legacy Systems

I had the opportunity to collaborate with Comsysto Reply on the further development of the Used Car Platform. A particular challenge in the project was to integrate the modern cloud application into an existing system landscape with legacy systems, thus achieving a rapid go-live. Comsysto Reply significantly contributed with outstanding expertise to sustainable solutions. The collaboration was always partnership-driven, which is why I would recommend Comsysto Reply at any time.

New Home Screen for Customers

Just coming out of the Stakeholder Review. I am absolutely thrilled by what I have seen. There was so much of what we at RIO stand for and want to stand for: starting from the customer perspective, rather getting something done fast than building ages without feedback, create and measure impact to then decide how to continue. And that all with a cross-functional team. I am impressed... Congrats to the Team!
