What you need to do is codify this imbalance in ownership. If you're bringing more to the table you get more. It begs the question: what's the other person for? As that other person does more they might get more...or they might not. One thing I've learned in tech is that sales is much more important than product. There are people who can sell stuff that isn't built. There are even more people that can build stuff that doesn't sell. Don't be that guy.
