I think the comments that precede mine are valuable and should be the basis of your decision. I can offer a relevant perspective because I pursued my startup solo. I have said for a while that if anyone asked my opinion my response would be, "don't do it." My understanding is that Y Combinator prefers teams as opposed to solo founders because of the amount of work and the truly gut-wrenching process of bringing anything to market. I agree. I am fortunate because I am married. The strength of will not just to weather the storms, but to remain focused, positive and productive is a shared contribution with my wife and I. She has no interest in being considered a founder, but the value of her contribution in that regard, is indisputable. Even with a great support system and a decade of experience in my field everything took longer. When there's a "million" things to do and nothing else gets done while you are doing something it's easy to lose heart. So, I would recommend valuing the partnership beyond your individual contributions (assuming it is effective/satisfying/pleasant - aside from the split discussion). My personal opinion is that a quality partnership is worth 5-10% difference.
