I decided to start working on some project, software company run by 1 person. By now, my contribution is pretty big and from the beginning, I told him, that I don't want money (as little as there was).
Right now the condition has changed. There is a moderate amount of money and I kind of want some. Is it ethical to even ask for it at all?
EDIT: It's time consumption is just too big and growing and the thing has grown lots
EDIT2: There is no contract or signing, the owner owns everything and I just have been contributing
EDIT3: Not money for previous work, just further work. Also the general timeline is a year from me starting and 9 months of "actually" working every few days few hours, first months were emailing basically.
