  Motivated by the $b\to s\ell^+\ell^-$ anomalies recently reported by the LHCb
collaboration, I present a class of flavored U(1)' gauge extensions of the
Standard Model that naturally accommodates them and possesses a rich
phenomenology. This model is characterized by the presence of tree-level
flavor-changing interactions in the down-quark sector, protected by
off-diagonal quark-mixing matrix elements. Anomaly cancellation fixes the
extension of the symmetry to the lepton sector in a very specific way, giving
rise to flavor-conserving family-non-universal Z' couplings. The fermion
content of this model is the same as in the SM while the scalar sector is
extended with an extra Higgs doublet and a scalar singlet. The model will be
tested in the next run of LHC and presents specific correlations in certain
flavor observables that allow to clearly discriminate among them and from other
new physics signals.
