I think what would make it work and give it life would be if all members of CoTech had to pool a % of revenues/ profits and then that money was allocated via CoBudget.
I really REALLY think the systematic pooling of resources within CoTech is needed for the network to be successful (it is what pretty much every single successful co-op network does).
Perhaps we could start with something like what the Valley Alliance of Worker Co-ops do? i.e. pay dues of 1/8 of 1% (i.e. 0.00125%) of their revenue to cover CoTech’s operating expenses and pool 5% of their profits into a co-operative development fund/ CoBudget.
We could of course choose different %s to those, but I suggest those as one of the lowest %s I’m aware of in other successful co-op networks.
