Plus or minus tiny details, the description from the article:
A demand co-op is a cooperative that pools and directs the spending power of its members. Demand determines what gets built, who survives, and where wealth flows. Most communities already have enormous spending power, but because that demand is unorganized, the value created from it is captured by outside businesses and investors. A demand co-op coordinates that spending so economic activity can build communal businesses, assets, and long-term ownership instead of constant leakage.
covers a multitude. Eg: CBH from the 1930s onwards has pooled the spending power of grain farmers into building out farmer owned transportation networks (rail, ports, shipping, large scale silo storage) as communal assets and source of jobs for relatives and communities.* https://en.wikipedia.org/wiki/CBH_Group
