So I've got an informal meeting with a VC this week - originally, the meeting was setup to talk about positions within the startups he's funded. The meeting took a while to happen because of various delays/vacations - and during that time I've come up with an idea I'm executing on. But it isn't ready to show, and, quite honestly, I'm not sure a VC would be interested in it, but they might be. Should I just talk about the positions, or bring up the idea? I'm concerned I'll appear to be all over the place (does the guy want a job or to run his own shop), when the reality is that the side project is an exploration at this point. My current plan is to NOT discuss the idea as I don't have a prototype working yet (probably 1-2 months), but then contact him again later when I've got something to show. Thoughts?
