Sébastien first worked for several small technology companies, which included developing the Wi-Fi subsystem of the Nabaztag/tag (150000 units sold). Then, in 2007, he founded M-Labs (fka Milkymist), an open hardware community and company. One unexpected highlight has been the reuse by NASA of the M-Labs memory controller and its successful launch on board the International Space Station in 2012. Since 2011, Sébastien is providing specialized software, gateware and electronics engineering services - often open-sourced - to laboratories such as CERN, DESY, NIST and the Paul-Drude-Institut. Sébastien also founded the EHSM conference on the frontiers of open source.
