This is terrible advice if I've ever seen any. You do not start a productive long-term relationship my lying to investors or treating them like shit.

I have noticed a growing trend in generally arrogant founders in the past few years, and it's disappointing to see. I do have a strong "no assholes" criteria, and won't fund such founders no matter how good everything else looks. At the end of the day, a startup is people first, and life is too short to work with assholes.
