Since the release of the first TESS sectors, the high resolution spectrograph CORALIE on the Swiss 1.2 m Euler telescope has observed more than 300 TESS Objects of Interest (TOIs). This work has been conducted in collaboration with the TESS Follow-up Programme to best support exoplanet-observations with larger telescopes, such as HARPS and Espresso. Within a wide range of science cases, we have covered a diverse set of TOIs spanning stellar types, orbital periods and transit depths. Amongst our sample of TOIs, we find that 43% are still unresolved planet candidates, 26% have been confirmed as planets, 2.5% are brown dwarfs and 20% have been identified as eclipsing stellar binaries. We wish to present an overview of the first three years of spectroscopic vetting and follow-up observations. We will also demonstrate our latest data release of spectra, cross-correlation functions and radial velocities, which are publicly available through the DACE platform (dace.unige.ch).
