Partners that take more than 50% aren't really your partner, they're just employing/using you. They'll come up with all kinds of wonderful excuses as to why they shouldn't pay you, like they're the "business" person, they have to support their spouse but you're just single, it was their idea, etc etc etc. The best thing you can do is ask for 50%, then when they refuse, get out of the partnership. It took me a couple of decades to learn this simple truth, and cost me (I don't even want to think how much) money. I basically worked for less than $1 per hour for YEARS. If you take the 10%, then treat it like investment income and don't do any more work on the product. It's a big world out there, and the opportunity cost of sticking with it is the income you could be receiving from other projects. Sorry to be harsh, but this is the #1 thing I wish I would have told myself when I was young and motivated.
