Say a little more about what space you are in. Let me assume that you have a consumer product -- an app, or a piece of hardware. There are things out there that do something vaguely similar, but you think yours is better. Go to the comments sections of various chat boards that are discussing the current way of doing things. Make note of the complaints. Ask the people there if they will chat with you for 5-10 minutes about a product idea. Be polite.
