  Using the dS/QFT correspondence in the context of inflation allows for the
study of interesting, otherwise inaccessible physics. In particular, by
studying inflation via its dual field theory at the boundary of the de Sitter
space, it may be possible to study a regime of strongly coupled gravity at
early times. The purpose of this work is to completely express cosmological
observables in terms of the free parameters of a dual field theory and to
compare them with CMB data. In this way, constraints on the observational
parameters constrains the validity of the strongly coupled inflation picture by
imposing limits on the parameters of the field theory. The fit with data
defines a limit for the consistency and validity of the approach taken and
shows that, within this limit, the model is almost unconstrained, but quite
predictive, producing power spectra of density perturbations extremely near
scale invariance.
