The CSI Team

Customer exaltation is our main objective. We see ourselves as service provider and double check everything we do by taking a look at the task from our customers' perspective. All of us live this philosophy daily - starting with the director and not ending with the car washer.

In times of digitalization and connectivity, CSI pioneers the hail market introducing new digital products and automated processes. Nonetheless, the human being - our customer - plays the main role in the act. We are conscious about the specifics of our business and we choose our employees wisely. Through internal training and growth programs, CSI can raise its own business leaders, who fully incorporate our customer-driven business culture. We grow together and create trust, allowing us to take fast decisions and to work efficiently in formal circumstances as well as in a very informal environment. Our team is small but highly capable to take any challenge.
