The goal of a private company is, first, zero to one. Get past the product market fit, figure out whether people actually care about what you're trying to build and someone will pay you money for that. That's the zero to one problem. So scaling, one through N, is figuring out can you do that at scale and how big is the scale. And when people pay you more than what it costs for you to make it, does that equation end up leaving you with money left over, i.e. profits.
