This is a TED talk, just released on the TEDblog yesterday, although it was recorded last year. David Rose presents it as 10 things you need to know before you pitch your plan to a venture capitalist. I think it’s more universal than just pitching to venture capitalists; it applies just as well to talking about your business to anybody.
For example, in about the middle of this, he points out how what you might think are silly, easily explainable errors throw off your credibility. And beyond that, this is a good treatment of presentations in general, pitch presentations specifically, and what matters to investors.
So see what you think . . .
