I present a model of gauge mediation without a messenger sector. This is the first phenomenologically viable model of this type. The sector of dynamical supersymmetry breaking couples directly to the standard model gauge groups. The apparent gauge unification is preserved despite the direct coupling. The inverted hierarchy mechanism plays a crucial role in dynamics. The model is completely chiral, and hence there is no need to forbid mass terms by hand. Still vector-like messengers emerge as a consequence of dynamical breakdown of gauge symmetries.
