About Us

Nolwen and Quentin are engineers, CentraleSupélec graduates and former elite athletes. They founded Fenxi Technologies on one shared conviction: technology has to stay clear, beautiful and useful. A particular care for detail, design and aesthetics — that is where the difference usually plays out, between a product that works and a product that makes a real difference.
