Our name

The words Nyx and Hemera represent two realities from which the name of the company originates in Greek mythology: the shadow and the light. Nyx is the goddess of the night and Hemera, the goddess of the day.

Our logo

The logo is made of a black box where the word NYX is written in yellow letters. Underneath, a line made of five yellow spheres represents lights. On the right side, HEMERA written in black on a white background brings a strong contrast, both visually and symbolically. The whole signature forms a rectangle made of shadows, light, and technology that are the foundation for our worldwide plans.
