  We consider the most minimal scale invariant extension of the standard model
that allows for successful radiative electroweak symmetry breaking and
inflation. The framework involves an extra scalar singlet, that plays the
r\^ole of the inflaton, and is compatibile with current experimental bounds
owing to the non-minimal coupling of the latter to gravity. This inflationary
scenario predicts a very low tensor-to-scalar ratio $r \approx 10^{-3}$,
typical of Higgs-inflation models, but in contrast yields a scalar spectral
index $n_s \simeq 0.97$ which departs from the Starobinsky limit. We briefly
discuss the collider phenomenology of the framework.
