I don't know about fully open, but I think Buffer is an example of a company that shares unusually much. https://buffer.com/resources/revenue-dashboard/ https://buffer.com/resources/revenue-dashboard/ There's some sort of list at https://openstartup.tm/ https://openstartup.tm/ but I think a lot of companies listed there are open with only select pieces of info. Both of these are about public sharing though. Employee sharing is trickier to know from the outside. Perhaps Valve Software because of the lack of hierarchy?
