Does anyone know a truly good Ads platform?

Recently I was trying hard to find a mobile ads platform however it ended up pretty frustrated. It seems non of them support keywords or demographic targeting except choosing categories(racing, action etc.), genders or ages. In the end I can only turn to Facebook or Twitter for a more specific targeting (people who loves multiplayer and fishing, etc.)

Do you have same problem with me? Does anybody know any mobile ads platform that can allow me target those features?

Thanks in advance!
