This is the first article I've read that mentioned what the typical return on a fund is. I have had educated guesses, but why don't we see this broadcast more broadly. Is it that only LPs care? I'd generally prefer to get investment from people whose judgement has proven they know how to get a good return on an investment, because founders typically get the same "return" from that stage on.
