I think we just need better platforms for enterprise procurement.

The issue is that currently you either publish as free & open-source and get tons of traction and usage but little funding, or you publish as paid and get no traction.

The blocker for paid software isn't actually the money itself (this is solvable by just pricing it reasonably), it's all the red tape that someone has to go through to get their company to purchase a license to begin with.

Maybe a marketplace that preemptively does audits, provides insurance, code escrow, licensing, etc ahead of time, that vendors can put their software on it proactively and companies can have accounts where their employees can just open an "app store" and just buy/license software directly? Similar to the AWS marketplace but for libraries.

It already exists. Tailwind has had GitHub sponsorships enabled for years but only 5 people have ever given them money that way.
