I would have a hard time imagining your chances of success would be even close to equal as having two founders. From what Zack and I have found when working on our site, we have peaks and valleys of output. Both of us have other responsibilities (meaning we are not funded and have other income we have to bring in), and life just happens: when I am in a lull, usually Zack is pushing stuff out and vice-versa. Very occasionally we both lull at the same time and user interaction suffers, traffic drops and we get a swift kick in the ass to get moving again :) Not to be saying it can't be done, but, be prepared to do nothing but the startup (get some funding, live off savings etc).
