For several decades \, the quark model suggested 60 years ago as a classification scheme for m ultiquark states had been a powerful and successful tool to understand and predict properties of hadronic states in QCD.

However\, since 2 003\, when the Belle Collaboration discovered the X(3872)\, an enigmatic s tate in the spectrum of charmonium with the properties at odds with the pr edictions of the quark model\, a new era in the spectroscopy of hadrons co ntaining heavy quarks began.

Since then\, many new states in the spectrum of charmonium and bottomonium have been discovered that do not f it into the quark model scheme and qualify as exotic states. Most of them reside near strong open-flavour thresholds that leave imprint on their nat ure and properties.

I will discuss how one can extract the infor mation contained in the experimental data on exotic hadrons with heavy qua rks and employ this information to make predictions for not yet observed h adrons and their properties.
