How and how do organizers of an esports tournament make money?

Question

Monetization

Hello dear geeks and just users. I am one of the organizers of an esports tournament. We already have more than 3-4 high-quality tournaments on our shoulders, it's a pity so far only in one discipline and with small prize money. But the players are satisfied with the quality of the tournament and everything else too.
I would like to ask the pros if there is any specific moment of tournament monetization, what to focus on and what you can earn on?
I will be glad to any answer :) Thanks in advance.
