My understanding: there are a lot of varieties of coops, consumer coops (REI, the Green Bay Packers, in some respects) are primarily owned by their customers, purchasing coops like ACE Hardware are owned by a group of businesses to increase buying power, and most relevant to this thread, worker coops are where workers own the enterprise. Multi-stakeholder cooperatives blend multiple forms of ownership to try to align the incentives of the enterprise with everyone who has a stake in its success. To me, it sounds really hard to get right, but also transformative if you can, so I’m very interested to learn more!
