Can you point out some existing ones with traction? I'm looking more at the list of people who are on board with it ("Trusted by open source creators" section) than who is actually running it, which I think is more important to get buy in than whoever is pulling admin strings in the back.
You said: "There are many existing projects like this", directly followed by "That's kind of the point, there are none." when asked for an example. Which one is it?
It's seems like a pretty thankless fundraising job but one where having connections to companies, banks and experience with distributing funds comes in handy. What's in it for a VC? I'd assume incoming deal flow and connections to new open source companies.
Seems more promising to me than a technical open source maintainer stepping up to do it on the side. But time will tell.
