One of the easiest ways to rule out people who are pitching to me is when they don’t know the details of their business. There are easy tell-tale signs. I’ll start with an obvious one – I talk with the entrepreneur about competitors. You can always tell during this discussion whether the entrepreneur has logged into their products, talked to their customers, read all the news stories and gotten all of the back channel info on the competition. You can tell if they have a deep-seated competitive spirit. Can’t go a mile deep on competition? Buh-bye.
