  The LHCb experiment is designed to study properties and decays of heavy
flavored hadrons produced from $pp$ collisions at the LHC. During Run~1, it has
recorded the world's largest data sample of beauty and charm hadrons, enabling
precision spectroscopy studies of such particles. Several important results
obtained by LHCb, such as the discovery of the first pentaquark states and the
first unambiguous determination of the $Z_c(4430)^-$ as an exotic state, have
dramatically increased the interest on spectroscopy of heavy hadrons. An
overview of the latest LHCb results on the subject, including the discovery of
four strange exotic states decaying as $X \to J/\psi \phi$, is presented. LHCb
has also made significant contributions to the field of $B_c^+$ physics, the
lowest bound state of the heavy flavor $\bar{b}$ and $c$ quarks. A synopsis of
the the latest results is given.
