Asynth is an independent French software company founded in Paris in 2009 by two architects, Isabelle Tristrant and Baris Saricoglu, and now based in Aix-en-Provence. It develops and publishes Space Designer 3D, a browser-based floor plan and interior design software launched in 2010. Homeowners, interior designers, architects, real estate professionals, retailers and educators use it to draw accurate 2D floor plans, furnish spaces from a large catalog of furniture and materials, and visualize their projects in real-time 3D with photorealistic rendering and AI image enhancement, with nothing to install. For businesses, Asynth also offers the planner as a branded tool on a company's own domain, along with an API for integration. Since the beginning, the goal has stayed the same: make 3D design accessible to everyone, with no CAD expertise required.
