The discovery of a light Higgs boson at LHC may be suggesting that we need to revise our model building paradigms to understand the origin of the weak scale. We explore the possibility that the Fermi scale is not fundamental but rather a derived one, i.e. a low energy mirage. We show that this scenario emerges in a very natural way in models previously used to break the electroweak symmetry dynamically and provide explicit realizations of this idea. Our scenario is built on the existence of an intermediate energy scale Λuv ~ 1010 GeV, which is suggested also by the results of the stability analyses of SM-like Higgs sector.
