Valve is far from a typical company. While technically not, they operate pretty much like a worker owned cooperative. Have a look at their employee handbook: https://www.valvesoftware.com/en/publications
(and Igalia, the company presenting in OP is really a worker owned cooperative).
holy crap I want to work there. I never had any idea they had such a radical structure (or lack thereof)
