Interior design software firm Rayon secured €10 million in Series A funding led by Partech. This capital raises the company’s total funding to nearly €16 million as it prepares to expand its AI and 3D architectural design features.
Why it matters
The company aims to consolidate fragmented design workflows into a single browser-based environment for multi-user collaboration. These funds support the expansion of go-to-market operations and the development of technical tools for architectural planning.
The Rayon platform currently supports imports of PDFs, images, and DWG plans alongside a floor plan vectoriser and an AI tool that generates blocks from photographs. It has achieved a total of nearly €16 million in funding.
The players
Rayon
A startup building a browser-based interior design platform that integrates AI tools, vectorisation, and collaborative project management.
Partech
A global venture capital firm focusing on technology-driven startups that led this Series A funding round.
The details
Rayon functions as a web-based environment where architects and designers can collaborate on project drawings in real-time using shared web links. It uses a floor plan vectoriser—a tool that converts raster images into editable vector geometry—to streamline the digitisation of building layouts. The platform further integrates project data directly into drawings, allowing multiple users to work simultaneously within the browser.
Timeline
September 29, 2026: Rayon announced the Series A funding round.
Before the end of 2026: The company plans to release V4 with integrated AI and 3D features.
The Tech Race
The platform moves to challenge the dominance of traditional, desktop-locked CAD suites by centralizing design and data in a web-based, collaborative environment. This push reflects a broader trend of migrating architectural design workflows to cloud-native, browser-accessible stacks.
Professional designers and architects can currently utilize the platform's browser-based tools for importing PDFs and DWG files. The release of advanced AI and 3D capabilities remains projected for future integration by the end of 2026.
The takeaway
Rayon is positioning itself to capture architecture workflows by replacing siloed desktop files with a real-time, browser-native collaborative stack. Watch for the release of V4 before the end of 2026 to see if the firm's AI-generated 3D features meet industry performance standards.
What happens next
Rayon is scheduled to release its V4 platform update, which includes new 3D and AI-driven features, by the end of 2026.
