I get asked a lot what presentation format to use when talking with venture capitalists. Well, I have used many different forms, but it never hurts to first map it to the Sequoia Pitch template. Or course these days, who really even needs to have a pitch or a product, pretty much whispering "bitcoin" will get you $20M (just kidding), but while there are many different templates, this is a good one.
What I really like is putting the Problem and solution up front and then the Why Now as that is the core thing which is having a solution to a real problem that real people have and have some reason why it hasn't happened yet. Very useful.
