I'm fortunate enough to be on a Spiral Grant 🙏  and think this is a great model to support projects or people you like but maybe not great to attract new people to the space.

I suspect you don't want to build a big pool of devs that you pay and direct to work on this and that cause that is of course the most direct way of getting dev attention to the problems you want to get solved.

Devs are not necessarily good at marketing (themselves) or at hiring other devs to increase their capacity to take on load but maybe you can help with that like the Bitcoin Design Community grants help many projects that are dev-heavy to solve non-dev issues.

You know who built the gossip client and NDK. Help them hire people to advance your goals.
