The radiative seesaw model is one of the simplest scenarios of physics beyond the Standard Model that can account for neutrino masses and dark matter at the TeV scale. It contains another scalar doublet and three additional Standard Model singlet fermions, all odd under a Z2 symmetry. I will consider a new realization of this scenario in which the lightest singlet fermion does not reach thermal equilibrium in the early Universe so that it behaves as a Feebly Interacting Massive Particle (FIMP).
