All of S23About sizeless
sizeless is the spatial AI to plan, build, and maintain the world's infrastructure by automating the 3D documentation and planning of the world’s underground infrastructure. Construction crews capture a short smartphone video of a construction site and get an automated, millimeter-precise digital twin with automatic part identification. We compress weeks of manual surveying and back-office planning work into hours. Our documentation and planning platform is currently in production: we have signed 7 paid pilots in 3 months with a potential ACV of $1.4M. sizeless (https://sizeless.co) spun out of research in robotics and spatial AI: co-founders Cornelius von Einem (PhD, ETH Zürich) and Roger de Belsunce (Physics & AI postdoc at MIT) lead the technology, while Julius Schilling (insurance, Aon) leads the commercial side. sizeless is building the proprietary training-data layer that all construction robots will run on.
