My grandfather founded a construction company that became quite successful and remained privately owned by him. When it was time for him to retire, he sold the company to the employees who turned it into a worker cooperative. They have since seen wild success and many dozens of people have made some incredible amounts of money. The culture my grandfather established remains present. I believe the key was never going public and therefore avoiding being controlled by external investors with no stake in the company’s culture.
