An attractive explanation of the flavor puzzle of the Standard Model is the multi-scale origin of the flavor hierarchies, where the SM Yukawa couplings of the different fields are generated at different scales. An interesting way to implement this idea is by extending the gauge group of the SM to a non-universal larger group. In this setup, an approximate global U(2) flavor symmetry minimally broken can emerge, that allows to circumvent the stringent flavor bounds for New Physics, opening the possibility of interesting UV completions of the SM at the TeV scale. In this talk I will explore this approach to BSM physics and discuss different realizations and their phenomenological implications.
