Good entrepreneurs are good networkers. They know how to find prospects in a crowd. Upon finding a supporter to advance his cause, the entrepreneur will get fifteen minutes or so to make a pitch to the network. If little or no interest is garnered, it is a sign that something is wrong. Pitching the same proposal to more investors will likely produce a similar result.
Angels invest in people.
They know that most successful companies today are not doing what they set out to do in their original business plans. The founders' talents, skills, and commitments are often revealed in their articulation of their vision and plan and it is these facets that attract angels. As an added bonus, those who do get angel funding will find it easier to attract traditional financing because of the reputation and connections of the angel backers. VCs like co-investing with angels. In some cases, VC's have co-invested with angels after having initially rejected a submission.
