ELI5: How do sites that don't display ads make money?

I'm talking about websites like streamable.com, torrent sites etc. (only examples I can think of).

As website you can make money by selling ads, but also by selling user data.

Alternatively, the site is devoid of money making schemes as part of its growth strategy, and will monetize once it secures enough market share. 

Why bother showing adds when you barely get 100 visitors a day, better keep it add free to develop a proper following ,and only then switch on the adds.
