And there you have it, the core of the Silicon Valley concept, the ideal startup, the business model of VCs.
1. Create a new product.
2a. Create a new market; have first mover advantage
or 2b. Use Predatory Pricing or Anticompetitive actions to gain advantage
3. Establish monopoly
4. Cash out big.
5. Use money to fund new business ventures, see 1.
Nom mobile games. Let's say team fortress 2 or other games subsidized to make game free for all. When a small portion are buying crates and skins.
Uber could do same with black car. Delivery services. Etc.. And then offer discount /free for the (multiple independent ride share or other) to those that want to be cheaper.
Very few people other than those pesky customers, seem to care if a business is actually making money on its own these days.
EDIT: typo ("irrelevant" -> "relevant")
There's so much in our world we could do if we only demanded profit, rather than 20+% profit YoY from every corner of our existence.
The business models that lead to hockey sticks are anything where the initial use is free to the user. Essentially, how Google, Facebook, and Twitter all started. They can use advertising to monetize that growth, and eventually ancillary paid services (Google Drive storage for example).
I have been sold to the Idea that Investors are killing any Internet "Business" by advising Founders against simple & straight-forward business plans. They constantly ask founders not to monetize earlier and wait until founders have no choice but to trash out the company/app to advertisers. The End Result is that founders get more and more scared of asking their customers for money.
If It was upto me, I would take 1000 paying customers over 100k free customers any day. Also this would mean free customers(subsidized customers in Uber's case) not hogging company's valueable resources and company could better serve lower number of paying customers.
Edit: I don't really know how to spell "customer".
