Inflationary spacetimes can be approximated by de Sitter space, which enjoys as many isometries as Minkowski space. These isometries are related to the conformal group in a simple fashion. I will show how the assumption of a quasi-de Sitter universe during inflation can constrain certain observables, like non-Gaussianities and so called consistency conditions between tensor and scalar power spectra. The constraints arise from the (weakly broken) conformal symmetry of the wavefunction of the Universe.
