We discuss an implementation of a discrete A4 flavour symmetry in holographic composite Higgs models that guarantees tri-bimaximal neutrino mixing at leading order. A generic feature of this construction is the possibility that the tau lepton is quite composite and it is accompanied by other composite states, related to it by custodial symmetry, the tau custodians. We discuss the possibility of discovering such states at the LHC.
