We present SAINT-EX, its first scientific results and summarize the observations acquired since its installation to date. SAINT-EX consists on the installation and operation of a one-meter telescope with an Andor Ikon CCD and filters optimized to obtain high precision light curves. It is located at the Observatorio Astronómico Nacional de San Pedro Mártir, Baja California. SAINT-EX's operation is remote and robotic, and since march 2019 until the beginning of the pandemic, our operations were regular and routine. SAINTEX, like the World, had to close for the pandemic, but fortunately in January and February 2020, we obtained the observations from which we derived light curves of TOI-1266 that allowed us to validate the planetary signature of the two transits identified by the TESS satellite Demory2020. After a full closure, in November and December 2020, we obtained with SAINT-EX the light curves that allowed us to validate another planetary system, this one composed of a single planet orbiting a low-mass, thick-disk M star Wells2021. Thus, SAINTEX and its team continue observing as the world crisis permits.
