ELI5: How do apps such as Hq Trivia earn profit from giving away money everyday? Where are they getting this money from?

They don't make ANY money... yet. HQ is run by the same people that founded Vine. They're burning through venture capital money right now in an attempt to get as many users as possible. This is similar to the business model used by Venmo, by the way.

Once they have a ton of users, they'll figure out a way to make money off of them. But they're not spending money that quickly, and they're getting tons of users. Eventually, they'll start running ads, like other internet companies.
