Now you know what not to say. Here's what you should say:
"This is what my company does..."
It's that simple. What you're trying to do is get potential investors to fantasize about how your product or service will make a boatload of money. They can't fantasize if they don't know what you do. And they don't want to be your friend, mother, or psychiatrist until they understand what you do, so cut the crap and explain what you do.
