  The CUPID-Mo experiment is searching for neutrinoless double beta decay in
$^{100}$Mo, evaluating the technology of cryogenic scintillating
Li$_{2}^{100}$MoO$_4$ detectors for CUPID (CUORE Upgrade with Particle ID).
CUPID-Mo detectors feature background suppression using a dual-readout scheme
with Li$_{2}$MoO$_4$ crystals complemented by Ge bolometers for light
detection. The detection of both heat and scintillation light signals allows
the efficient discrimination of $\alpha$ from $\gamma$&$\beta$ events. In this
proceedings, we discuss results from the first 2 months of data taking in
spring 2019. In addition to an excellent bolometric performance of 6.7$\,$keV
(FWHM) at 2615$\,$keV and an $\alpha$ separation of better than 99.9\% for all
detectors, we report on bulk radiopurity for Th and U. Finally, we interpret
the accumulated physics data in terms of a limit of $T_{1/2}^{0\nu}\,>
3\times10^{23}\,$yr for $^{100}$Mo and discuss the sensitivity of CUPID-Mo
until the expected end of physics data taking in early 2020.
