At Tonfunk, we also carefully handle customer ideas. They are thoughts or visions; they can initiate development and become signposts to a successful future. Therefore, handling them demands experience, competence and understanding of the respective technical scope of the task.

Coordination of an idea is in the hands of experienced engineers, from concept creation through validation, development of test models, and all the way to prototype creation.
