Coops, exactly. These days I'm reading the Mars Trilogy by Kim Stanley Robinson (WARNING: minor spoilers), and he mentions a lot the system of coops in the new Martian economy. One of the examples mentioned is a real-life one: the Mondragón Corporation, the world's largest coop with 80,000 employees and more than 14 billion euros in revenue.

(For anyone interested in economics, politics, geology and many other topics, this Hugo-winning trilogy is a great read. https://en.wikipedia.org/wiki/Mars_trilogy)
