10-20-30 Rule

This is the rule if you are going for a pitching - requesting for a funder to fund your business idea. But might also be good for sales presentations.

In summary:
10 - Prepare your slides not more than 10 slides.
20 - Present your presentation within 20 minutes.
30 - Use the minimum of 30 points for font size.

Simple video but I thing this is important when you do business pitching.
