This is very interesting, and maybe goes against normal reasoning. I've heard the general idea is not to become business partners with friends, but the opposite seems to be true with startups. In the two startups I've been involved in previously, I hung in there because I didn't want to let the other person down. One ended up dissolving, but we remain on good terms. The other is ongoing, where I freelance, but give it my all because I don't want to let the other person down. The third is new, and I just was approached by an old friend who wants to get involved. I thought about it for a second, then realized he's the kind of person I don't want to let down and I'm pretty sure the feeling is mutual.
