I agree. You can certainly do it without the "background", but we specifically had to get some well-connected "right-backgrounded" people involved before folks would answer our calls because all our principals had degrees from schools they never heard of (Ben-Gurion University of the Negev) and experience in little niche defense contractors that aren't "cool" by SV standards.

(However, we did what we needed to do--get some Stanford people with ties to Sand Hill Road--and got it done.)
