  In these proceedings we discuss a flavor-safe explanation of the anomaly
found in $R_K= {\cal B}(B \to K \mu^+ \mu^-)/{\cal B}(B \to K e^+ e^-)$ by
LHCb, within the framework of composite Higgs models. We present a model
featuring a non-negligible degree of compositeness for all three generations of
right-handed leptons, which leads to a violation of lepton-flavor universality
in neutral current interactions while other constraints from quark- and
lepton-flavor physics are met. Moreoever, the particular embedding of the
lepton sector considered in this setup provides a parametrically enhanded
contribution to the Higgs mass that can weak considerably the need for
ultra-light top partners.
