We show that gauge‐singlet real scalars added to the Standard Model can both soften the little hierarchy problem and offer a candidate for Dark Matter. Masses of the scalars are in the 1–3 TeV range, depending on the Higgs boson mass and the number of singlets present. If the scalars couple to the Majorana mass term for right‐handed neutrinos then one neutrino must be massless. The mixing angles are consistent with the tri‐bimaximal mixing.
