The CUPID-Mo experiment at the Laboratoire Souterrain de Modane (France) is a demonstrator for CUPID, the next-generation ton-scale bolometric 0νββ experiment. It consists of a 4.2 kg array of 20 enriched Li2Mo100O4 scintillating bolometers to search for the lepton-number-violating process of 0νββ decay in Mo100. With more than one year of operation (Mo100 exposure of 1.17 kg×yr for physics data), no event in the region of interest and, hence, no evidence for 0νββ is observed. We report a new limit on the half-life of 0νββ decay in Mo100 of T1/2>1.5×1024 yr at 90% C.I. The limit corresponds to an effective Majorana neutrino mass ⟨mβ
