Stanislas Chaillou

Stanislas Chaillou is Co-Founder and COO/CPO at Rayon, a Paris-based browser-native CAD platform transforming how interior designers collaborate on space design using AI.
Trained as both an architect and applied-AI researcher at EPFL and Harvard GSD (Class of 2019), Stanislas previously served as Senior Machine Learning Engineer at Spacemaker AI, the Oslo-based design startup acquired by Autodesk for $240M in 2020.
A published author and educator, Stanislas authored 'Artificial Intelligence and Architecture' (Birkhauser, 2022) and taught generative AI at IAAC Barcelona, bridging the gap between computation and architectural practice.
At Rayon, Stanislas leads product and operations, championing an AI-first drawing experience that integrates generative tools directly into the design layer, serving clients such as Virgin Atlantic.
Rayon has generated over 4 million drawings since its 2021 launch, raised nearly 16M euros in total funding including a 10M euro Series A led by Partech, and grown its team to 35 people.
