My co-founder and I were sitting in Coupa cafe two years ago with a couple of VCs who told us that the Youtube co-founders had pitched them right from the same booth we were were sitting at. "Did you invest in Youtube?", I asked, to which they said, "no - the idea seemed preposterous at the time".

"Well", I said, smiling, "you'll probably think our idea is just as preposterous, and saying you didn't take the jump like it's a badge of honor probably means your firm won't work for us".
