I'm not sure this list passes the "mutually exclusive" test - for example, eBay fits into both the "marketplace" and "auction" category. "Freemium SaaS" is clearly a strict subset of "SaaS". Might seem like a minor quibble, but a categorisation system isn't very useful if the categories are all jumbled up.
I'd probably focus on pure "revenue models" as they're easier to define. Then you can ask: who pays you (all your users / some of your users / someone other than your users), how often do they pay you, and how much do they pay you? The benefit of this scheme is you can plot different revenue models on a 2-dimensional or 3-dimensional graph. Eg, if all of your users regularly pay you a little, you have a B2C subscription business. If someone other than your users occasionally pays you a lot, it's likely you're selling user data or high-end advertising. If your users pay you a one-off, medium amount, it's likely you're in ecommerce or equivalent.
I'd also look at the most frequently used revenue models first, because I think people are sometimes tempted to find "innovative" ways of making money when boring old banner ads would do better. Advertising, subscriptions and selling physical or virtual products seem to be the most proven business models. Affiliate marketing or transaction fees can work, but they're harder to pull off. Stuff like "selling user data", contrary to popular belief, only works if you really know what you're doing (I briefly worked on one of those "subscription food service" ideas with the bright idea of selling customer feedback data - turns out there's a ton of enterprise companies like BrandView already selling far more detailed customer data).
That kind of info is more useful imo because it actually helps people figure out a model that's more likely to work.
Who gives you money?
1) All users
2) Premium users
B) Company's that pay for groups of Users
D) Referral Programs
The list itself is amazing and just what I have been looking for, though. :)
Anybody can edit Wikipedia without logging in, why not this?
Some other opensource projects also fund parts of their development through donations, either from businesses or consumers.
It won't make you rich, but it might bootstrap you into some better revenue model.
Also awesome list, definitely saved for later :)
It says the last update was five days ago, so I take it that you missed it. Either that or the "last update" feature is borked.
that he wanted this "final" version to be edited by invitation only and wasn't sure how to make the change to the original version.
