Pay Attention to the Insights of Co-Founders
If you’ve ever applied to an accelerator or approached (many) investors for funding, one of the most important points they check, especially in the case of investors, is team.
Above all, they want to know about the co-founders, and truth be told, most investors shy away from a startup with a solitary founder, the stated reason most often being that you should be able to find at least one person who shares your vision or passion and is willing to throw in with you. It’s also difficult to operate in a vacuum: much easier if you have that other person off whom to bounce ideas, and to keep you in check, if need be.
