Ask HN: How would you fund a tech cooperative owned by workers and users?

I built a marketplace for therapist friends (sana.so) and we're trying to turn it into a proper cooperative. Inspired by David Graeber's anarchist ideas, I want to create a tech tool that's genuinely owned by both users (therapists) and workers, with direct voting rather than committees (Voting in committee members doesn't feel democratic enough for me). What models or examples should we investigate for funding and governance?
