We construct asymptotically safe extensions of the Standard Model by adding gauged vector-like fermions hereby completing the theory before reaching the gravity scale. Using large number of flavour techniques we argue that all gauge couplings, including the hypercharge, and the Higgs coupling achieve an interacting ultraviolet fixed point.
