You should check whether the people from VC firms who've contacted you are associates or partners. If they're associates, you're no closer to a deal than if they hadn't contacted you.
Thanks for the tips pg. Of the people we've spoken to, its been a mix of associates and partners. I guess what you are saying is that none of it really matters until you get a term sheet. That's fine with us, since we are not desperate for money. The type of value add we're looking for is guidance/networks/advice, not monetary.
