Very interesting question because a pitch is like a piece of art. That’s why its “Art of the Deal” or “Art of the Pitch”. It can be anything from your hand movements and eye contact to the information you’re providing. To the way your voice fluctuates during key moments or the silence and the way you reply to the questions that have been asked. It is for YOU to maximize all the attributes you have as a person when communicating and to try to stay away from your weakest points to provide the best pitch possible. Of course, it’s always best to have as much information that you can provide, but they say 70% of communication is body language, 20% is how you say it, and 10% is what you’re saying.
