Heh I have an entire division of my business based around this idea. People create an idea in isolation and then realize nobody wants it!

There's a specific strategy for doing so, and I help these product creators reorient their marketing to (here's the hint:) tie in with what their target market already believes.

From what you shared, my interpretation is:

> you haven't gotten specific enough on your target market, at least the INITIAL niche

> you haven't figured out the value equation

> your marketing message doesn't match up with what the people you wish would buy actually believe.

I have to tell you, most product creators in your position fail. Well, it ain't gonna be a cheap or fast fix, but it can be done.
