1,000 True Fans (2008)

As a creator who is about halfway to building her thousand true fans, I gotta say that Kickstarter and Patreon have both made it a hell of a lot easier to survive on the way to pumping out enough product to get $100 every year from each True Fan. Patreon especially.
Best of luck with your work.

Right now I'm mostly mooning about with a bad case of seasonal depression, and sssslllloooowwwwllllyyyy working on the beginning of my next two comics. And the kickstarter for the last volume of Rita.
Though the underlying idea is sound: you don't need to be a mainstream star to make a living. You just need to be loved enough, valuable enough to enough people. You needn't to appeal to everyone. Instead, find Your People, find your niche.
The article even says, "ONLY" 1,000 true fans which seems to be a way of making the idea within reach of the everyday layman/procastinating wantrepreuner.
I would argue that to get 1,000 true fans your work has to be brilliant to a point of gaining a kind of religious zeal within a small number of a much larger audience.
This is just my opinion though.
So I think there is a sustainable business model where, rather than trying to go mass-market, you sell a specialized product to a much smaller number of very dedicated fans.
If you knew how much money your favorite customers made, and asked for just one day of their income to support you, it becomes trivially easy to work out a definition of sustainability for your business.
For SAAS businesses, the number of "true fans" that are therefore required could be ridiculously low. 100? Maybe 10!
