Gauthier Schweitzer is co-founder and CTO of Sahar, a French OSINT software publisher specializing in the processing and visualization of massive data sets, for public and private sector players. A graduate of Sciences Po Paris, École polytechnique, HEC, and ENSAE, he combines training as both an engineer and an economist, which he applies to tools for technological sovereignty.
