There are several software companies whose license models are based on your revenue. Not "free until you make money", more like "$X to get a license and then additional costs based on your annual revenue".

I agree.

Just to add that most people don't consider those licenses "open source", only "source available".

There are other possibility that is dual license, i.e. AGPL for everyone, but the business can buy a non AGPL version it they don't want to publish their secret sauce.

I'm not sure if someone is mixing the two approaches.

I may have confused the issue - I was answering in more generic terms. There are license agreements that are based on overall revenue.

I wasn't commenting on the OP's question of an open source license or whether anyone would pay based on the revenue created just from that tool.
