Several theoretical arguments and many experimental evidences call, at present, for an extension of the standard model of elementary particles. The flavour puzzle and the nature of dark matter are undoubtedly among the most important and challenging ones. Although they separately point towards the existence of New Physics, these two mysteries may in principle have a common explanation. In this paper, we will discuss how precision physics can be exploited to realize an explicit connection among flavour and dark matter. Firstly, we will discuss the state of the art of phenomenological studies of semileptonic B-meson decays, in particular 
and 
. Secondly, we will review the importance of a peculiar mechanism of production of dark matter, the so-called thermal decays, as a concrete way to find combined solutions to the anomalies observed in flavour data and to the abundance of dark matter observed in our Universe. Interesting prospects for the future will be also discussed in detail.
