The founder of the last startup I worked at made 100k per month and wasn't even the CEO, and that was pre-product and pre-revenue. He just raised a bunch of money on a pitch deck.

I'm definitely not saying that's common, but it's not unheard of either. Inside Silicon Valley there's a tightly prescribed set of norms that tend to be followed, but outside of there money tends to change hands a lot more quickly and fluidly. That's the benefit of being in a place like NYC, because people tend to be motivated more by self-interest rather than by trying to look cool or fit in, so it's a lot easier to pitch folks on stuff if you find a novel but rational opportunity.
