Sure you have. Amazon grew without giving stuff away for free. Customers paid (just below market rate) from day 1. This demonstrated the -convenience- of ecommerce. It had revenues from the first sale. Yes, it spent mountains of VC money on marketing and development, but -not- on just buying stuff for you so you think it'll be free forever.
Uber is the same, although it's less clear that users will pay gor what a ride really costs. (And their margin makes it attractive for competition)
In both cases though there us revenue from customers from day 1. You can wind prices up. It's really hard to "go from free to paid".
