We present a flavor-dependent U(1)_X gauge extension of the standard model that naturally explains the number of fermion families, generates small neutrino masses via the scotogenic mechanism, and predicts two stable dark matter candidates. This leads to a two-component dark matter scenario with rich phenomenology. The model also features flavor-dependent couplings and a new gauge boson Z', offering testable signatures via flavor-changing neutral currents and collider searches.
