Selling the stocks is the one-time operation, right? So you get paid once... Is there any other scenario, when you get % of revenue constantly, e.g. on a monthly basis for the rest of your life? i.e. even if you leave the company (maybe after some vesting period). Here, I say "revenue", because in case of "profit" the company can reinvest it, leaving you with nothing. EDIT: So basically, is there a way to transform your employment into a passive income?
