What are Some Sustainable Community Business Model Examples?

I have 90K followers on twitter in the food & beverages space. I have been trying to find a good business model to be able to make my community a sustainable business. My ultimate goal of building this network is to build my next products/businesses on top of. So far, the only source of revenue has been from 1-3 months sponsorships and one time off ads. I am looking for existing community business models to get ideas from other than getting subscriptions from existing members. Would appreciate your thoughts.
