KESPRINT is a collaboration of around 50 exoplanetary researchers, located in some 20 institutes covering a large part of the world. This group concentrates on carrying out follow-up observations of data from space missions dedicated to the observation of exoplanetary transits. The importance of a ground based follow-up program (FuP) when interpreting such results can not be overstated. The verification of the existence of the exoplanet through detection of radial velocity variations or through validation by excluding all other sources (typically background binaries) through e.g. Adaptive Optics imaging, need to be carried out. It is also required to know the fundamental parameters of the host star with very high precision in order to discern the planetary data. Recently, asteroseismology have also started to play a key role.

Here we briefly describe the work of this collaboration and highlight some important results.
