I will discuss how the Hybrid inflationary potential can lead to
observationally compatible predictions in a regime where the defect field is
light, and more than 60 e-folds of accelerated expansion occur after the
symmetry breaking transition. Considered in such a regime, the model is an
example of hill-top mechanism, for which analytical expressions giving f_NL
can be derived. Using these expressions as a guide, we identified
parameters leading to significant non-Gaussianity and satisfying WMAP
observational bounds. Focusing on a particular example leading to large fNL,
I will discuss the likelihood of the initial conditions at horizon crossing.
