We present a very minimal model for baryogenesis by a dark first-order phase transition. It employs a new dark $SU(2)_{D}$ gauge group with two doublet Higgs bosons, two lepton doublets, and two singlets. The singlets act as a neutrino portal that transfer the generated asymmetry to the Standard Model. The model predicts exotic decays of the Higgs and $Z$ bosons, $\Delta N_\text{eff} = 0.09-0.13$, and stochastic gravitational waves, all detectable by future experiments.
