As a founder of an SF tech company that now makes tens of millions of dollars a year, our revenue was never enough (or made fast enough) for the investors we talked to when we were raising our early rounds. Sometimes, if we made $X in 6 months, the VC's "no" was "We would have liked to see you make that in 3 months". It's why I have a tough time watching Silicon Valley -- it's too accurate and painful to watch.
