I disagree. Three is better than two. no more, no less. Look at Youtube as the perfect case study. Jawad, the thrid foudner, gave up operation dutities togo back to school. he still advised, and was paramount in the early stages of the company/product. If the OP has already found one right partner (it takes more than just chemistry), then losing that person may harm you and your business. At a same time, a 3rd founder who is a specialist could really help you in this situation. I don't think I can add any more value about that than it's been already said here. Goodluck and make sure to post updates as to your founder search.
