  We propose that neutrino masses are "seeded" by a dark sector within the
inverse seesaw mechanism. This way we have a new, "hidden", variant of the
scotogenic scenario for radiative neutrino masses. We discuss both explicit and
dynamical lepton number violation. In addition to invisible Higgs decays with
majoron emission, we discuss in detail the pheneomenolgy of dark matter, as
well as the novel features associated to charged lepton flavour violation, and
neutrino physics.
