Discerning patterns and trends in the physical properties of exoplanets is now possible thanks to the growing number of planet discoveries. In particular, TESS has been instrumental in adding to the sample with the detection of over 7000 potential planets, of which nearly 600 have been confirmed in the last 7 years. The distinct subpopulations that have emerged from grouping planets in different parameter spaces are now being tested against formation and evolution theories. Linking the two is still proving challenging in some cases, highlighting the need either to revise the current theories or, for rare planets, to increase the statistical sample. In this talk, I will discuss the efforts to validate TESS planet candidates with the TRAPPIST , SPECULOOS, and ASTEP ground-based facilities, focusing on small and giant planets orbiting M dwarfs. I will then present some of our most impressive results, including the discovery and study of the TOI -4336 A system, and the first confirmed planets from the MANGOS programme.
