There’s also the cooperative. Here in Switzerland they are rather popular - some of the biggest banks, insurances and property owners, and more notably, the two largest supermarket chains (making up >80% of food / non food market) are organised this way. Your customers could be part of the ownership structure of your company, which creates a strong loyalty effect and a focus on organic & vertical growth rather than growth just for the sake of beating quarterly numbers.
