Answer:
10/20/30 rule was coined by Guy Kawasaki, a Silicon-Valley based author, speaker, entrepreneur, and evangelist. Kawasaki suffers from Ménière’s disease which results in occasional hearing loss, tinnitus (a constant ringing sound), and vertigo— something that he suspects can be triggered by boring presentations (among other medically-proven things). While he may have been kidding about presentations affecting his Ménière’s, it did inspire him to put an end to snooze-worthy pitches once and for all. As a venture capitalist, he’s no stranger to entrepreneurship, pitches, and everything in between. We’d be willing to bet that he’s heard his fair share of pitches that have fallen on deaf ears (almost literally, in his case).
To save the venture capital community from death-by-PowerPoint, he evangelized the 10/20/30 rule for presentations which states that “a presentation should have ten slides, last no more than twenty minutes, and contain no font smaller than thirty points.”
