But that's not enough. Take Uber, which is losing millions each year despite being valued at $50 billion. They even introduced a carpool service that's only costing them more money, probably because wanted to snatch the name "UberPool" before Marvel used it for a Nietzsche / Ryan Reynolds mashup.
It's the same all over. We've told you before of how Spotify and Shazam are deeper in the red than the Egyptian Navy. Airbnb, whose business model is "save money on hotels by putting up with the smell of cat piss," is losing $150 million a year, and isn't expected to turn a profit until 2020. YouTube brought in a staggering four billion dollars in 2014, which was good enough to, uh, break even. Even Reddit, which it's easy to forget is even a business, can't get in the black by monetizing its 70 million users. Hell, if we had 70 million users, we'd ask each one for 50 cents and then buy a spaceship.

As countless abandoned Xanga and Myspace pages taught us, a good idea means nothing if you can't dominate the market. Someone else will take your idea, improve it, and leave you in the dust. You have to monopolize the market at all costs, and then you can worry about the trivial little detail of making money.
