Fred Wilson today blogged about the “panel pile-up,” in which a dozen or so entrepreneurs line up to pitch him after speaking at a conference. Not surprisingly, Fred doesn’t believe such situations are ideal for in-depth interactions (he suggests folks just take 60 seconds to give name, rank, serial number and why you want to meet with him).

Anyway, it got me to wondering if any VCs have done a deal in which the initial point of contact was made as part of a “panel pile-up.” I threw out the question in this morning’s peHUB Wire, and received two positive replies. Get them after the jump…
