Value proposition
Professional-grade CAD that runs in the browser and is built for interior design. Plans, styling, specifications and schedules live in one connected environment, so specs update when the drawing changes. Teams co-edit in real time and share by link instead of exporting files.
Products and solutions
Rayon browser-based 2D drawing/CAD platform (imports PDF, image and DWG), custom block libraries and template library, AI floor-plan vectorizer that turns scanned or photographed plans into editable drawings with walls, openings and zones, AI block generation from photographs, mobile-first app, client presentation mode, V4 release planned for end of 2026 with 3D and a broader AI suite.
Unique value
The first design layer built specifically for interior design rather than retrofitted from architecture and engineering CAD. It is Figma-style collaborative, runs in the browser, and puts AI in the drawing layer so generated output stays editable and connected to project data.
Target customer
Interior and experiential designers, independent design studios, and large operators in commercial real estate, hospitality, retail and workspaces that run space-planning and feasibility studies.
Industries served
Interior design, Architecture/AEC, Commercial real estate, Hospitality, Retail, Workplace/fit-out, Co-living and hostels
Technology advantage
A high-performance browser CAD engine where the drawing and the data are the same object. AI is integrated natively into the drawing layer, including vectorization and block generation. The co-founder brings deep AI-in-architecture research, including GAN-based floor plan generation. The platform has passed 4M+ drawings created.
How they differentiate
Unlike desktop CAD and BIM tools such as AutoCAD, Revit and SketchUp, Rayon is browser-native, collaborative and purpose-built for interior work. Unlike consumer floor planners such as Planner 5D, it offers professional CAD/BIM-grade precision, specifications and schedules. Its AI features produce editable native geometry rather than static images.
Main competitors
SketchUp (Trimble), Autodesk AutoCAD/Revit, Planner 5D / RoomSketcher / Cedreo (browser-based floor planners)
Notable customers
Virgin Atlantic (airport lounge design), CityHub (reports saving €10K/month), Coloc Housing (saving €11K/month on feasibility work), Nolt Mathis, Morning
Major milestones
Oct 2021: founded. 2022: €1.7M pre-seed led by Seedcamp and closed beta launched. Sep 2023: €4M seed co-led by Northzone and Foundamental, plus public launch. Sep 2026: €10M Series A led by Partech, alongside launches of the mobile app, presentation mode and AI vectorizer. V4 with 3D and a full AI suite is planned for late 2026.
Growth metrics
4M+ drawings created on the platform. Team tripled to 35 people (it was 13 in 2023). Total funding is close to €16M.
Market positioning
A challenger to legacy CAD in a roughly €50B underserved interior design software market. It positions itself as the collaborative 'drawing layer' for interior design's AI era.
Geographic focus
Europe-headquartered (Paris) with worldwide users, including UK and international enterprise customers.
