This is tautological, unless you have a definition of “success” other than “be worth a lot of money”. Which raises the question of whether that should be the measure of success. A great many creators are scraping by on merch sales and now Patreon, devoting themselves to making the things they love full-time. If they do it consistently and garner an audience who loves their work, is that not success? You might even call them small businesses… and yet, they don’t have stock worth a lot of money. But the investment model doesn’t leave any room for that kind of success, because the primary thing investors want is to get richer. You provide an incredibly useful service that everyone uses and loves? Great. How much money does it make? How much money do I make? Did you try putting ads on it?
