I like experiments in having employees actually own companies, or make their own decisions, but the closest I see in the consumer facing sector is stuff like REI or Valve software maybe — and that is only at the pleasure of its actual owners.
By contrast, HOAs and housing cooperatives like Mitchell-Lama, or credit unions, are truly owned by their members. A growint number of DAOs online are as well.
Most universities have an element of democratic governance as well.
Other than that, most other concerns is owned by outside shareholders, with some shares often traded on a public stock market, but the ones who call the shots are the same people who sit on each other’s boards and lobby Congress etc.
