Aurorin CAD

Y Combinator just backed a company that's about to make every mechanical engineer question why they put up with garbage CAD software for so long. Aurorin CAD is building the next generation of computer-aided design from scratch—a completely new kernel, not some wrapper around 40-year-old code that everyone's been suffering through. And they're AI-native from day one, which means this isn't your dad's AutoCAD with a chatbot bolted on.

Here's the deal: CAD software designs satellites, robots, cars, everything physical in this world—and it's been running on the same slow kernels since the 80s. Engineers spend more time watching loading spinners than actually designing. A single modification cascades into hours of manually fixing downstream features, constraints, and references. It's medieval. Aurorin built their own custom parametric and B-Rep kernel specifically for modern CPUs and GPUs, so parts that take hours to load elsewhere open instantly. Their AI chat interface lets you design complex parts conversationally while still keeping full UI control. Both worlds, best of both.

Available now for Mac and Windows. If you're still using software that was old when your manager was in college, this is your sign.
