  "account": "Paris-based interior design software company Rayon has secured €10 million in Series A funding to develop its AI-driven drawing layer for the industry. The investment round was spearheaded by Partech, with contributions from existing investors Northzone, Foundamental, and Seedcamp. This brings Rayon's cumulative funding to about €16 million, following a €4 million Seed round in September 2023 and a €1.7 million pre-Seed round in 2022. Esteemed angel investors supporting the company include Norman Foster of Foster + Partners, David Basulto of ArchDaily, and Joe Thomas of Loom.\n\nPartech's General Partner, Réza Malekzadeh, highlighted the rarity of this opportunity, noting that Rayon is the first team to build the design layer for interior design that was previously underserved by software. The company's co-founders, Bastien Dolla and Stanislas Chaillou, aim to create a unified browser environment for plans, styling, specifications, and schedules. This integration allows users to import various file formats, build custom block libraries, and collaborate in real-time, providing a performance and feature set that surpasses many legacy CAD software.\n\nRayon's web platform boasts over 4,000 library items and 100 templates, catering to diverse building types such as housing, retail, and offices. Notable clients include Virgin Atlantic for airport lounge designs, hostel group CityHub, and Coloc Housing, which has saved €11k monthly by testing layouts before involving architects. Design studio Nolt Mathis has also adopted Rayon by discontinuing a 15-year-old CAD subscription. The company's upcoming version 4, slated for release before year-end, will integrate AI capabilities directly into the drawing experience, complementing existing 3D tools.\n\nWith the newly raised capital, Rayon plans to focus on launching 3D capabilities, embedding AI into its design experience, and expanding its go-to-market efforts. This funding comes as part of a broader effort to address the €50 billion interior design industry, which has long been overlooked. Since its founding in October 2021, Rayon has introduced a mobile-first app, presentation mode for client collaborations, and an expanded template library, all aimed at democratizing access to professional-grade CAD software.",
