When pitching investors, you might say and do everything precisely right, yet still get a no in the end. What gives? Oftentimes, "this is less about your company and whether it is a good one, and more about the internal dynamics of the fund," Mark MacLeod writes. Investors may already be overweighted in your industry, for instance, or they may have had a bad experience in the past with an idea similar to yours. So just because the answer is no, "you should not assume you don't have a great business," MacLeod writes.
