Expertise

Three playgrounds, one standard.

Digital sovereignty

Tools you actually control: open source software, self-controlled hosting, reversibility. Raysys contributes directly to the digital commons backed by the French State, such as La Suite Numérique.

  • La Suite Numérique
  • DINUM
  • Sovereign hosting

Open source

Open source is not an option: it is the method. Upstream-first contributions, long-term project maintenance, active involvement in communities — from OpenFUN to Clermontech.

About

Raysys is the company of Manuel Raynaud, a software engineer based in Clermont-Ferrand, France.

Raysys was founded in January 2025 to give this activity a proper frame: helping public and private organisations build sober, sovereign and shared digital technology.
