I will say that the fact that you're only making $9/hour at a company that's supposedly about to go big is a huge red flag. If you've made as many contributions as you say you have, then there's something very wrong. Either you have failed to negotiate fair compensation for yourself, or the company is banking that you will continue to break your back for the chance to go big.
The last time I made $9/hour was hauling bags of salt at a retail warehouse selling pools. If I were you, I'd go back to school. $9/hour is not only unsustainable, but a serious red flag regarding how the company views their relationship with you.
