Twin Higgs (TH) models explain the non-discovery of new colored particles responsible for natural electroweak symmetry breaking. I will discuss supersymmetric UV completions of TH models that feature natural electroweak symmetry breaking even for stop and gluino masses above 2 TeV and show that the Lightest Supersymmetric Particle which generically resides in the twin sector is a natural dark matter candidate with promising signals at future direct-detection experiments.
