  There are a lot of works within a class of classically scale invariant model,
which is motivated by solving the gauge hierarchy problem. In this context, the
Higgs mass vanishes at the UV scale due to the classically scale invariance,
and is generated via the Coleman-Weinberg mechanism. Since the mass generation
should occur not so far from the electroweak scale, we extend the standard
model only around the TeV scale. We construct a model which can achieve the
gauge coupling unification at the UV scale. In the same way, the model can
realize the vacuum stability, smallness of active neutrino masses, baryon
asymmetry of the universe, and dark matter relic abundance. The model predicts
the existence vector-like fermions charged under $SU(3)_C$ with masses lower
than $1\,{\rm TeV}$, and the SM singlet Majorana dark matter with mass lower
than $2.6\,{\rm TeV}$.
