VCs don’t owe you a goddamn thing—and especially not after they’ve already met with you. That was the time they had for you. They offered a meeting—no more and no less.
The fact that you didn’t spend the last few minutes of the meeting asking for specific feedback and posing the question of whether or not the VC was going to move this forward as a champion of the deal or at least whether they wanted to schedule a next call is your failure. When you’ve got any kind of a lead—be it for selling your product or selling your equity—and you let them go with no scheduled next step, you risk never speaking to them again.
That’s your problem, not theirs.
