On paper you're close to rich, in the sense that your stock in the company is worth a lot. But it's illiquid, and most of it may not legally be yours yet because of vesting. On the other hand, after a series A round you'll be able to pay yourself a decent salary-- maybe 1/2 or 2/3 of market rate, which will probably be a great improvement.

In a startup you generally want to make your salary as low as possible. You're not going to get rich from salary but from the company scoring, so why take money out of it?
