I wonder how viable a sort of "micro PE" firm would be, basically a company that just buys many of these micro indie projects with positive cash flow with the goal of holding on to them for profit or investing into their operations and eventually reselling them.

There's been this trend of new firms popping up that acquire small ecommerce brands (in fact, there was one on HN just the other day). I'm wondering if the same model can (or has) been applied to small "indie" companies and projects.
