Having users is an unpleasant business. They make you scale your product, they cost money to sell to and always complain about not having enough. Now, investors? Those guys are great. You give them a pitch and a slideshow and they’ll throw millions at you. Once you try your series A funds, just IPO, then market to the public and get them to buy your stock. The big investors see the stock go up and buy, and the retail investors see big investments so they buy. Eliminates all kinds of hassle.
