The main point of my article was the surprise around the extent of the VC network and the helpful interactions with them. Before going through this process, VC was a black box to me. Now, a lot less so.
A few folks below have pointed out that I must have had an extensive VC network to draw on. Not quite. I knew 3-4 VCs casually from having worked at a couple of other startups. None of them invested in us by the way. It certainly didn't hurt to get their advice. Now, of course, I have a rolodex full of dozens I could potentially call up at some point, which is useful. I can see how founders who have done it before likely find it a lot easier to get the ball (and the checks) rolling.
