IACOB is an ambitious long-term observational project whose main scientific goal is to provide a complete and statistically significant empirical overview of the main physical properties of Galactic massive OB-type stars. The ultimate objective of the project is that the compiled information can be used as a long-lasting anchor point for our theories of stellar atmospheres, winds, interiors and evolution of massive stars. In this endeavor, we are benefiting from: [1] optical, high-resolution spectroscopic facilities attached to 1-3 m telescopes in the Canary Islands observatories; [2] state-of-the-art tools and techniques to perform single snap-shot and multi-epoch quantitative spectroscopic analyses (providing accurate estimates for the stellar/wind parameters, rotational velocities, abundances, as well as information about stellar phenomena giving rise to spectroscopic variability such as binarity, pulsations, rotational modulation, and wind variability); [3] parallaxes and proper motions provided by the Gaia mission; and [4] photometry provided by the TESS space mission. In this contribution to the MOBSTER-1 virtual conference, held in the middle of the Covid-19 global pandemic, I summarize some of the observations and results obtained up to June 2020 in the framework of the IACOB project which could be of interest for establishing synergies with the MOBSTER project.
