I present extensions of the Standard Model where the global symmetries baryon and lepton number are gauged and subsequently spontaneously broken. These models have intriguing consequences due to the requirement of anomaly cancellation demanding the introduction of additional fermions: the new lepto-baryon fields can be a dark matter candidate and/or generate neutrino masses. I discuss symmetric and asymmetric dark matter, neutrino masses, as well as the generation of the baryon asymmetry in these scenarios.
