Agriculture has a lot, utility services including fiber internet, electrical, and natural gas, many credit unions, there are a few retail stores like REI, mutual insurances, a number of pharmacies and homecare and other health services are co-op, many other worker co-ops, and there are a decent number of housing co-ops. Other than maybe a few rural fiber co-ops most are not super fast growing businesses, and they lack attention seeking rich owners, so they don't get a lot of attention, but co-ops as a whole has steadily gained more market presence nearly across the board over the decades.
They're a worker owned co-op and have grown very nicely over the years.
