Rayon Raises €4M in Seed Funding


Rayon, a Paris, France-based providing a collaborative design tool for the architecture, engineering and construction industries (AEC), raised €4M in Seed funding.

The round, which brought the total amount to €5.75M, was led by Northzone and existing investor Foundamental. Previous investor Seedcamp and angel investors, including legendary architect Norman Foster (Foster + Partners), also participated

The company intends to use the funds to grow the team, in particular, hiring engineering, design and growth talents to support the development of the platform’s next iteration. 

Founded in 2021 by Bastien Dolla and Stanislas Chaillou, Rayon provides a collaborative design tool for the architecture, engineering, and construction industries (AEC). Users can import a variety of files, including images, PDF, and CAD documents (DWG, DXF), and then get to work using its design and sharing features. From drawing and annotations to layouts and styling, Rayon has everything designers need to output their work from feasibility studies to detailed, rendered floor plans. One-click link sharing makes it easier to work with colleagues and stakeholders to incorporate revisions and make changes based on real-time feedback instead of being locked away in email inboxes. Early customers have already reported that the platform makes their work up to three times faster, improving quality, efficiency and productivity. 

The cloud and browser-based tool can be run from any operating system, anywhere, enabling teams and stakeholders to collaborate on 2D floor plans in real-time, making the process faster and more agile.
