The measurements of b→sμ+μ− processes at LHCb and BELLE have revealed several tensions at the 2−3σ level. Combined fits to the available data suggest that these tensions might have their common origin in New Physics beyond the SM. In this talk I will discuss the impact of a generic class of models featuring new heavy scalars and fermions that couple to the SM fermions via Yukawa-like interactions. The models induce one-loop contributions to b→sμ+μ− as well as to the anomalous magnetic moment of the muon, and I will discuss the possibility of a simultaneous solution of the respective anomalies.
