- Product will be open-source after achieving N active users - Product will be open-source after achieving N in revenue
I think this could help startups in competitive/commoditized markets, who want to open-source but are too small to enforce their license on bad actors with complete ripoffs which I read about on HN before. I'm thinking of GPL, AGPL, but also other more restrictive licenses like BSL. It incentivizes community to help the startup grow.
(I believe I have seen "after 36 months" type of pledges before, though can't remember where.)
You don't mention the area you are targeting or your biz model, so I can't help on that side. But I wouldn't be so thrilled to contribute to something that "might be" or "will become" open source. I have seen projects that do "funded development", where features are added based on customer or $$ flows -- like "feature X will cost $2k, so 10 new customers or equivalent community contributions and we'll work on it".
