It may help to take a look at Marcia Yudkin's works on marketing to/for introverts.

Replace "introvert" with "deep person / product" if that's a more comfortable model.

Self-promotion is a really important area of consideration here and our shouty marketing culture is really kind of unipolar about it until you know what to look for. Good luck.
