The future TESSERACT experiment will search for individual galactic Dark Matter (DM) particles below down to 10 MeV. Multiple target materials will be used with varying detection strategies to actively reject the so-called low-energy excess and discriminate nuclear recoils against electron recoils.  Nowadays, the TESSERACT project encompasses two US-based technologies, namely HeRALD using superfluid helium as a target material, and SPICE using polar crystals (Al2O3 and SiO2) and scintillating crystals such as GaAs. The possibility to host the future TESSERACT experiment at the Modane Underground Laboratory and to add a third French-based cryogenic semiconducting (Ge, Si) detector technology to the TESSERACT payload will be detailed.
