This, in two words, is the secret of the new marketing.
Find ten people. Ten people who trust you/respect you/need you/listen to you...
Those ten people need what you have to sell, or want it. And if they love it, you win. If they love it, they'll each find you ten more people (or a hundred or a thousand or, perhaps, just three). Repeat.
If they don't love it, you need a new product. Start over.
Simple. Accurate. Hard to do. Necessary.
