1) What if your company is indeed growing but not scaling at the rate that it needs? An investment would boost that ability correct? An owner would be able to hire more employees, perhaps buy more necessary technology, etc.
2) I don't think that is good advice. Zuckerberg had built things previous to Facebook but never anything that made money. I am not as familiar with Twitter and Pinterest's founders but I don't believe they had money-making businesses before. If a service is good and attracts people, why not build it??
1) Then you're not in the "early founder who just jumped out of the corporate world" ship anymore. Congrats. You're now the owner of a successful business looking to scale.
2) That's a lottery ticket, not a plan. 99.9% of the facebook-alikes failed so miserably you didn't even hear about them. That's roundabout your chances if you go that way. I wouldn't quite my job for a 0.1% chance of making it.
