Something many keen investors look for, when they evaluate a business startup, is whether or not the company is a one man (or woman) show, or if they have a partner on board. The reasoning ought to be fairly obvious - if someone cannot convince their own friends that they have a good idea, or worse, has no friends, it does not reflect well on that company. Even if neither of these issues are actually present, there is still a deep concern. For one, there is no obvious person with an emotional attachment to the company who can criticize potentially hazardous decisions.
