Have you guys incorporated yet? I'm assuming you have but in any case, the sooner you guys settle the shares/vesting the better. How much of an asset do you consider yourself to be in the company? If you were to leave next week, would the company suffer a huge loss? If so, you have the edge and I do believe you deserve more than a 10% stake, even for the work you've done thus far.

EDIT: I also agree that you don't always need to raise money. If you guys have the means to continually fund yourselves (as you mention break-even in 3 months), it's really not necessary especially once you hit a substantial profit margin.
