Rayion

Rayion, also known as Rayon, is a software-as-a-service (SaaS) company that has developed a collaborative, browser-based design platform for architects, interior designers, and other professionals in the construction and real estate industries. The company was founded in Paris, France, in October 2021 by Bastien Dolla and Stanislas Chaillou, who combined their experience in browser technologies, AI, real estate, and architecture. Rayon aims to modernize the design process by moving it online, allowing teams to draw, share, and collaborate on floor plans in real-time, which contrasts with traditional, offline CAD software.

The platform serves clients ranging from architects and interior designers to project managers and furniture manufacturers. Its core features include professional-grade CAD tools for fast and precise drawing, the ability to import and convert PDF and DWG files into editable plans, and extensive libraries with over 4,000 elements and textures. Rayon's business model is freemium, providing basic functionalities for free while offering more advanced features like team workspaces, unlimited model history, and live support through paid subscriptions. The software facilitates real-time multiplayer editing, commenting, and annotation directly on the designs, streamlining feedback and decision-making processes.

Since its founding, Rayon has secured significant funding from investors. After a pre-seed round, the company raised €1.9 million in June 2022 and a subsequent Series A round of $4.23 million in September 2023, with backers including Seedcamp, Northzone, and Foundamental. The company is focused on expanding its platform's capabilities, incorporating AI-powered semantic search to help users find design assets intuitively and exploring features like visual search and deeper data integration to become a comprehensive hub for the design and architecture industry.
