  Building on recent advances in the understanding of gauge-Yukawa theories we
explore possibilities to UV-complete the Standard Model in an asymptotically
safe manner. Minimal extensions are based on a large flavor sector of
additional fermions coupled to a scalar singlet matrix field. We find that
asymptotic safety requires fermions in higher representations of $SU(3)_C\times
SU(2)_L$. Possible signatures at colliders are worked out and include
$R$-hadron searches, diboson signatures and the evolution of the strong and
weak coupling constants.
