  Sweet spot supersymmetry is a phenomenologically and cosmologically perfect
framework to realize a supersymmetric world at short distance. We discuss a
class of dynamical models of supersymmetry breaking and its mediation whose
low-energy effective description falls into this framework. Hadron fields in
the dynamical models play a role of the messengers of the supersymmetry
breaking. As is always true in the models of the sweet spot supersymmetry, the
messenger scale is predicted to be 10^5 GeV < M_mess < 10^{10} GeV. Various
values of the effective number of messenger fields N_mess are possible
depending on the choice of the gauge group.
