I have exactly this problem with our product, and have known for over a year what the solution is. If you can't tell whether your product is viable, talk to its prospective customers until you can.
Unfortunately, this is awfully hard for nerds like us to do. One way I know this to be true is by watching people who have an easy time of it hustle through customer meetings, taking a product idea from zero to "purchase order" with nothing but some static web pages.
