Being married and running an all-out startup is probably a bigger risk (unless your spouse is completely on board and works there too) to your marriage than the other way around (or even adultery).<p>The reason is simple, you only have so much time to spend on all the things that you have to do in order to launch a successful company, this can easily lead to your significant other to feel neglected (whether that's true or not is up for debate). Long hours, business trips, business crises, they're all par for the course.<p>Having a supportive spouse can help enormously but it definitely is not a guarantee.<p>Investors are just as interested in the moral fibre of their potential partners as they are in their ability to go over and beyond the call of duty. Being married is not always an advantage.<p>Oh, and of course investors would never cheat on their wives...
