I present a study of several SM extensions which are free of Landau poles and instabilities until the Planck scale, stabilise the Higgs sector, and allow to accommodate discrepancies of lepton anomalous magnetic moments.
Our models feature a singlet matrix scalar field, three generations of vectorlike leptons, and direct links to the Higgs and flavor sectors via new Yukawa and portal couplings.
I will highlight properties the renormalisation group evolution, important phenomenological implications and some aspects of collider searches.
