I discuss a unified model of scalar particles that addresses the flavour hierarchies, solves the strong CP problem, delivers a dark matter candidate, and provides the trigger for electroweak symmetry breaking. Besides furnishing a unification of the recently proposed axiflavon with a Goldstone-Higgs sector, the scenario can also be seen as adding a model of flavour to elementary Goldstone-Higgs setups. Including constraints from flavour physics, we find that the model is very predictive, restricting the axion decay constant to a thin stripe of f_a ~ (10^11−10^12) GeV in the minimal implementation.
