In this talk, we shall provide a classification of extremal scaling geometries in Einstein-Maxwell-Dilaton theories, allowing for the possibility of a broken U(1) symmetry, and examine whether they constitute acceptable ground for holographic superfluids. We distinguish between scale invariant geometries with a constant scalar and solutions with a runaway scalar. We also study to what extent the former can mediate fractionalisation transitions when a relevant perturbation exists.
