Claper on stage

Our mission

To transform the most boring presentations into the most engaging experience.

« The first time I went on stage, the first feeling I felt was to be distant from my audience, left to myself and limited in my interaction with them.

Claper's mission is to help these people presenting an idea or a message by giving them the opportunity to make their presentation unique and to have real-time feedback from their audience.

On the other side, as a participant, when I am in front of a speaker I always have questions in my head or want to participate actively. Which is often complicated depending on the situation.

Claper's mission is to help each participant to take their place, to be an actor in the presentation, in the meeting and to feel important and useful.»
