Announcing Rayon's €10 million Series A
Building the drawing layer for interior design's AI era
“Rayon has completely streamlined our workflow. It makes everything easier and more efficient, which allows us to spend less time managing communication and technical steps — and more time focusing on the creative aspects of our projects.”
We are excited to announce today that we have raised €10 million in Series A funding, led by Partech, with continued backing from Northzone, Foundamental and Seedcamp. This new chapter comes as we cross 4 million drawings created in Rayon and grow to a team of 35 people, united by the same ambition: making great design tools accessible to everyone shaping interior spaces.

Interior design’s AI moment
For anyone working in interior design, the pace of progress in AI has been hard to miss. Generating a convincing image of a room now takes seconds. Exploring a mood, a material palette or a lighting idea has become dramatically more accessible. And as models become better at understanding geometry and carrying out increasingly complex tasks, their role in the design process will keep growing.
We believe this is an exciting moment for designers. More ideas can be explored, more options can be tested, and less time needs to be spent on repetitive work. It opens up room for the things that make a project worth pursuing in the first place: understanding how people live, finding the right atmosphere, and making thoughtful decisions about a space.
Bringing these capabilities into everyday practice, however, takes more than generating a beautiful image. A project has dimensions, constraints, specifications and countless decisions that need to hold together. Designers need to be able to shape what AI produces, refine it with precision, and work on it with their team.
We see the drawing as the place where all of this comes together.

Rayon on mobile and desktop
A few words on Rayon V4
Much of what we have been working towards will come together in V4, arriving later this year.
First, 3D is coming to Rayon! Bringing another dimension into the same collaborative environment will open up new ways to develop, understand and share a design. We want moving between a plan and a spatial view of a project to feel like a natural part of the drawing process.
V4 will also bring a broader set of AI capabilities into the app, spanning generative tools, AI-powered workflows, and agentic AI that can help carry out tasks within a project. Our goal is to make these capabilities useful throughout the design process, helping users move from an idea to something they can keep working on.
There is a lot more to share, and we look forward to showing you what we have been building. Through all of these changes, our focus remains the same: making a powerful design tool feel simple and approachable.
