CUORE-0 is an experiment built to test and demonstrate the performance of the upcoming CUORE experiment. Com- posed of 52 TeO2 bolometers of 750 g each, it is expected to reach a sensitivity to the 0νββ half-life of 130Te around 3 · 1024 y in one year of live time. We present the first data, corresponding to an exposure of 7.1 kg y. An analysis of the background indicates that the CUORE sensitivity goal is within reach, validating our techniques to reduce the α radioactivity of the detector.
