Flavourful Feebly-Interacting Particles (FIPs) in the MeV to GeV range have a strong impact on a large variety of precision frontier signatures. We focus in this talk on the current status and prospects of accelerator-based experimental limits and their interplay with the lepton anomalous magnetic moments measurements. In particular, we will tackle the challenging case where the FIP decays mostly into invisible dark sector particles and illustrate the resulting limits with the case of an axion-like particle.
