I disagree somewhat with the other posters about what you "deserve". You deserve about as much as you can negotiate. The more willing you are to lose the whole thing, the harder you can negotiate. That being said, if you go in to negotiate, don't go in with the fairness argument. Describe how you are excited about the company, appreciative of the offer and that you took the low equity because you were unproven, but now that you have proven yourself you would like more. Be prepared to sacrifice cash for equity or to walk. The one thing I would say is this, if you don't ask you definitely wont get more. I don't think any of us can truly judge if it is a good deal because we dont have enough information.
