Rayon, a collaborative drawing platform for interior design, has raised €10 million in a Series A funding round led by Partech, with continued backing from Northzone, Foundamental, and Seedcamp. The announcement marks a new chapter for the company as it crosses 4 million drawings created in its browser-based application and grows to a team of 35 people. The company says the capital will support its ambition to become the drawing layer for interior design’s AI era.
Interior Design’s AI Moment
Artificial intelligence is rapidly changing how interior designers work, with convincing room images now generated in seconds. Designers can explore moods, material palettes, and lighting ideas far more easily than before, while AI models become better at understanding geometry and carrying out increasingly complex tasks. Rayon believes this creates room for thoughtful decisions about how people live, how spaces feel, and which atmosphere best serves a project.
A Series A to Build the Drawing Layer
Rayon has spent five years building a fast, precise, and collaborative drawing environment in the browser, where plans, styling, specifications, and schedules live together in one place. The company sees the drawing as the foundation that carries the geometry and information needed to make a project understandable and editable. With the new funding, Rayon will accelerate its work, bring 3D into the product, and reach more people designing spaces around the world.
Investor Support and Market Opportunity
The Series A round welcomes Partech as a new investor, while Northzone, Foundamental, and Seedcamp continue to back the company. Rayon’s leadership said it is deeply grateful for that support as it builds its next chapter. The company views the investment as a signal of confidence in its approach to collaborative and intelligent design software.
Rayon V4 Introduces 3D and AI
Much of the company’s work will come together in Rayon V4, which is scheduled to arrive later this year. The update introduces 3D capabilities, allowing users to move between a plan and a spatial view as a natural part of the drawing process. It will also bring a broader set of AI capabilities into the app, including generative tools, AI-powered workflows, and agentic AI that can carry out tasks within a project.
Expanding Access Across the Industry
The funding arrives alongside several releases aimed at expanding access to capabilities that computer-aided design has historically kept gated. A mobile-first version of the software allows users to view projects, while a new presentation mode supports sharing drawings with clients in the room. An expanded template library further positions the company to serve a nearly €50 billion industry that has remained underserved for too long.
Team Growth and Open Roles
Rayon now employs 35 people who share a focus on design, engineering, and the details that make software enjoyable to use. The company is actively hiring and invites people excited about the future of design software to explore its open roles. Rayon also thanked its users for every project shared, piece of feedback given, and conversation held as it crossed the 4 million drawing milestone.
With fresh Series A capital and continued investor confidence, Rayon is positioned to expand its role in the interior design software market. The company’s roadmap for 3D and AI capabilities reflects a broader shift toward more accessible, collaborative, and intelligent design tools. Its upcoming releases are expected to show how the drawing environment can bring precision, automation, and teamwork together for designers worldwide.
