Check out the story behind Cisco before you give up.

And on another note, ask a VC if they reject you why they reject you, there really is a huge difference in the spectrum of available parties to work with, from assholes to fantastic people to work with and everything in between, make sure you partner with a group that feels right rather than just looking at the terms sheet. That's where the action is of course but sometimes it is better not to have a deal than to have a deal with the wrong party.
