Aurorin CAD
Aurorin CAD is building professional mechanical design software from scratch, replacing the 1980s-era geometry kernels inside tools like SolidWorks with a purpose-built, AI-native B-Rep kernel. The result: parts that take an experienced SolidWorks user 20 minutes to model can be created in seconds, either through a fast modern interface or by describing them in natural language to an integrated AI agent. Founded in the Y Combinator Winter 2026 batch by Michael Baron, a former 3x SpaceX intern and Apple GPU driver engineer, Aurorin positions itself as 'Claude Code for mechanical engineers.'
