Discrepancies between recent experimental results and their respective Standard Model predictions, known as flavour anomalies, are reported in semileptonic charged and neutral-current $B$-decays, the muon magnetic moment $(g-2)_\mu$, and the extraction of the Cabibbo angle. In this proceedings, we review two New Physics models that introduce two scalar mediators at the TeV scale and aim at a combined explanation of the flavour anomalies. The first model features the leptoquarks $S_1$ and $S_3$ and provides tree level solutions to both $B$-anomalies and one-loop level solution to the anomalous $(g-2)_\mu$. The second features the leptoquark $S_1$ and the charged singlet $\phi^+$. While $S_1$ provides the same solution to the charged-current $B$-anomaly and $(g-2)_\mu$ as in the first model, $\phi^+$ can accommodate the Cabibbo-angle anomaly independently and together with $S_1$ can resolve the neutral-current $B$-anomaly at one-loop.
