  Radiative seesaw models are examples of interesting and testable extensions
of the Standard Model to explain the light neutrino masses. In radiative models
at 1-loop level, such as the popular scotogenic model, in order to successfully
reproduce neutrino masses and mixing, one has to rely either on unnaturally
small Yukawa couplings or on a very small mass splitting between the CP-even
and CP-odd components of the neutral scalar mediators. We discuss here
scotogenic-like models where light-active neutrino masses arise at the
three-loop level, providing a more natural explanation for their smallness. The
proposed models are consistent with the neutrino oscillation data and allow to
successfully accommodate the measured dark matter relic abundance. Depending on
the specific realization, it is also possible to explain the W-mass anomaly and
to generate the baryon asymmetry of the Universe via leptogenesis. The models
lead to rich phenomenology, predicting sizable charged-lepton flavor violation
rates, potentially observable in near future experiments, while satisfying all
current constraints imposed by neutrinoless double-beta decay, charged-lepton
flavor violation and electroweak precision observables.
