  The Neutrino Option is a scenario where the Higgs mass is generated at the
same time as neutrino masses in the type-I seesaw model. This framework
provides a dynamical origin for the scalar potential of the Standard Model and
suggests a new approach to the hierarchy problem. Here we review the
preliminary analysis of Ref. [1], that showed the viability of this scenario,
as well as the improved study of Ref. [2], that led to a better identification
of the region of the parameter space where the Neutrino Option can be realized.
We find that experimental constraints from both Higgs and neutrino physics can
be accommodated introducing 2 heavy Majorana neutrinos with mass $M_1\simeq
M_2\sim 0.5 - 10$ PeV and Yukawa couplings to the lepton doublet of order $
10^{-4}-10^{-2}$, assuming that at the scale $M$ the classical Higgs potential
is approximately conformal, with a quartic Higgs coupling $\lambda_0\sim
0.01-0.05$. Specifying the light neutrino mass ordering, the ratio $M_2/M_1$ or
a given value of the top quark mass identifies narrower ranges for all the
parameters. Although no further signature of the Neutrino Option is generally
predicted at the currently accessible energy scales, conformal UV completions
have been proposed, that could be tested e.g. via detection of gravitational
waves. Leptogenesis can also be successfully realized in this scenario, that
intriguingly ties together the breaking of the conformal and electroweak
symmetries with the violation of lepton number.
