CUPID-Mo is a bolometric demonstrator experiment searching for neutrinoless double decay (0$\nu$2$\beta$) of $^{100}$Mo. The observation of this process, which is not allowed by the Standard Model, would determine the Majorana nature of neutrino and its mass scale. The CUPID-Mo detector array consists of 20 scintillating bolometers made of Li$_2^{100}$MoO$_4$ crystals (2.34 kg of $^{100}$Mo), assembled in a compact structure of 5 suspended towers. Data taking is ongoing in the EDELWEISS cryostat at the Underground Laboratory of Modane (LSM, France). The main goal of the CUPID-Mo experiment is to demonstrate "zero-background" conditions in the region of the expected 0$\nu$2$\beta$ decay peak of $^{100}$Mo with six months of measurement. The reproducibility of Li$_2^{100}$MoO$_4$ scintillating bolometers with high performance should be confirmed, demonstrating the applicability of the CUPID-Mo technology for the future ton-scale 0$\nu$2$\beta$ decay bolometric experiment CUPID.
