AGN-launched jets are a crucial element in the study of super-massive black holes (SMBH) and their closest surroundings. The formation of such jets and how they are able to propagate without breaking apart over large distances is the subject of ongoing, extensive research. Nearby radio sources are prime laboratories for testing jet launching scenarios, as well as studying their innermost sub-parsec AGN structure. Very long baseline interferometry (VLBI) offers a unique view of the immediate vicinity of BHs, unparalleled by other observational techniques. Combined with RMHD simulations and multi-wavelength observations it offers invaluable information about magnetic fields and their evolution, accretion flows, jet instabilities, and overall flaring behaviour. In this talk I will discuss recent efforts in bridging the gap between state-of-the-art simulations and VLBI observations of jetted-AGN.
