How would such a company come together in the very beginning? What would the formation process be exactly? I’m having a hard time imagining it because usually there’s one person or a few with expert knowledge, awareness of an opportunity, and a vision of what they want to achieve. They make great effort and sacrifice in the early days to take that vision from 0 to 1. They eventually build it up into a larger organization with employees, but it didn’t start that way. For those folks to only own 20% of their own venture - not even a controlling a share of their own baby - may not be enough incentive. Every company starts somewhere, so how would this system work in reality? On the other hand, if a large group of workers have a good idea for a new company and want to start one with shared ownership, they can already do that using an LLC or other corporate structure.
