2,550 community examples, torn down.

Every community in this index is a worked example of a business somebody already built: what they charge, how many people pay it, what they sell alongside the community, how long it has been running and which channels it grows from. Each listing carries a teardown of those numbers, and where somebody has written notes on what makes it work, those too.

Start with the model you have in mind. A $100-a-month room and a $9-a-month one are different businesses, and the collections below show real examples of each. Then read the category you know, where the page opens with what the whole category charges. When you can picture what you would build, the Idea Finder checks it against the same data.
