This is really well thought through and I applaud your effort.
I’m curious about the second bullet in Ownership:
Individual cook’s ownership will reflect how early they join Josephine and how much time/energy they invest (e.g. meals served)
Much like employment, where employees risk personal liquidity for a potential payout at the end, joining Josephine early as a cook is related to risk. However, it also seems related to access and the implicit privileges that come from knowing that a platform such as Josephine exists, which is only available if you’re connected to the same circles that employees and their first outreach efforts are in.
Have you considered this and thought about how to approach it?
