Having gone through it, I think the single most important things are missing. Your co-founder needs to have the same vision as you, they need to want the same outcome. And you don’t find out that you want different outcomes for a long time, it’s very very easy in the beginning to agree you both want a successful company, for your software to be awesome, and for money to roll in. Later when things get real, you may discover your shared vision isn’t quite as shared as you thought. The other thing I want in a co-founder is someone who will have my back unflinchingly and always when speaking to others, whether it’s investors or customers or just friends and family, because inevitably things will come up that worry you which can sow mistrust if not caught quickly. I was lucky to have such a co-founder, and I actually feel guilty for worrying that they didn’t always support me. I tried to return the trust at all times. But note that discovering differing visions can and does threaten your ability to know if a co-founder trusts you! I think it’s a miracle that companies survive, knowing how easy it is for people to want different things.
