We review theoretical and phenomenological properties of conformal rolling scenario, the novel model of primordial scalar perturbations creation. We focus on the particular prediction of this model, statistical anisotropy. We search for the corresponding signal in the CMB data, and establish the constraint on the unique parameter h2 of the conformal rolling scenario.
