I would say this is true in NYC, but not Silicon Valley. Our company is based in NYC and you're right about VCs not talking to you if you don't already have a concrete business model that's already generating revenue. However, it seems from my experience that the west coast is a completely different world. I'm sure there are many good reasons for this, but I wouldn't say that most VC's/investors won't talk to you, I would say that most NYC investors won't talk to you.
