How important is it that at least one of the co-founders in a tech startup is a willing and effective cold caller (to potential customers, investors, media, etc.)?<p>I've noticed a high correlation in my projects between success and having a co-founder who was willing to cold call. But that's a fairly small data set... have others noticed the same thing, or is it passe in a Web 2 world, or is it a skill you can just hire?<p>Is the importance dependent upon whether the startup is B2B, B2C, etc.?
