Successfully realised projects
I particularly appreciated two things in working with cronn: These were the very high quality standards of all employees we worked with and the very transparent communication and project management.
— Reiner Berg, Head of Development at Ingenico Marketing Solutions
The collaboration with cronn was a great enrichment! Due to the regular exchange and the constant thinking of the entire cronn project team, an uncomplicated and particularly effective cooperation at eye level has resulted, from which an excellent result has emerged.
— Laura Wittemann,Project Manager of m&p: public relations
What we particularly liked about the cooperation with cronn was the direct contact with the developers. Thus our requirements were met individually and professionally - for us the project with cronn was a complete success.
