No, I am sorry but as a developer you are the product, look at it this way, you can focus your development time on your own idea for free and retain 100% ownership. I never understood why developers accept 10% for building the whole thing, when they could work on their own ideas. I understand the need for someone who can sell, but it has been by experience that if you have a working product you can find someone to sell it, you only need someone who can sell, when you have something to sell. Now in saying that there is value in finding a co-founder that has domain knowledge of the market you are targeting and if they can sell great, I personally would not go into a "I develop the whole thing" arrangement without at least 30% and 50% if there are only two of us. Anything less than that and they have to start ponying up a salary, it is just not enough equity to take the risk, when I can go build something myself with that time spent. As well it sounds like you are dealing with people that feel that there is value in ideas. It has been my experience that those individuals (and their lack of experience, in start-ups) can feel like they did all the work they need to in coming up with the idea. This can create a sour environment where you feel like you are doing all the work.
