  We propose a unified setup for dark matter, inflation and baryon asymmetry
generation through the neutrino mass seesaw mechanism. Our scenario emerges
naturally from an extended gauge group containing $B-L$ as a non-commutative
symmetry, broken by a singlet scalar that also drives inflation. Its decays
reheat the universe, producing the lightest right-handed neutrino. Automatic
matter parity conservation leads to the stability of an asymmetric dark matter
candidate, directly linked to the matter-antimatter asymmetry in the universe.
