## About

Based in Paris, France, and founded in 2021 by CEO Bastien Dolla, and Stanislas Chaillou, Rayon SAS, a.k.a. Rayon, operates as a provider of a software platform that allows designers to draw, share, import, and export their digital workflow related to space design. In September 2026, Rayon SAS raised EUR 10 million in series A funding led by Partech Partners, with participation from Northzone, Foundamental, and Seedcamp.
The company provides collaborative space design software with a wide range of features, including import and export work, drawing ideas using the next-generation space planning tool, sharing plans and collaborating with friends and colleagues in the cloud, and access to resources for interior design and floor planning.

Rayon generates revenue from the subscription of its software packages, which include Pro (EUR 29 per month per user), and Team (EUR 60 per month per user).

The company will use the September 2026 funding to add 3D and AI features and expand sales.
