I think doing proper personal due diligence up front can often help you avoid a breakup; it can also help avoid starting a company together in the first place if the fit isn't there, and make breakups easier should they happen. I wrote a blog post about my own experience doing this with the co-founders of Otelic. We have since lost one co-founder in a completely undramatic way - which I largely attribute to talking everything through in great detail prior to starting. Many times you're so excited about working together on a cool product that you neglect to do this; it's happened to me before and it's a costly mistake to make. http://gigaom.com/2012/01/26/the-questions-every-founder-must-ask-themselves/ http://gigaom.com/2012/01/26/the-questions-every-founder-mus...
