Even for the stuff I've been hired to build, there was something there when I got there. It's your responsibility to insure that they have properly represented what they already have. Deception in the recruitment process is a real turn-off.
I agree, regarding deception. As for something being there -- that's kinda the point with a startup: there's quite possibly nothing there yet, but you get to help build it. Someone has to start the process. Just don't hire on with someone that expects you to do that and lies about it.
