About Aurorin CAD
Summary
Aurorin CAD builds mechanical CAD software for engineers, replacing legacy tools like SolidWorks, Fusion 360, and Onshape. It runs on a custom parametric and B-Rep kernel built for modern CPUs and GPUs, so files that take hours to open in existing tools load instantly. AI is embedded in the core, letting engineers design complex parts through a chat interface instead of navigating menus step by step.
Business model
A free individual tier plus paid team plans
Go-to-market
Mechanical engineers download the app for free on Mac or Windows; teams purchase through a separate sales path.

There are 2 problems: The first, CAD software is slow and the second, designing with it is a tedious process with many steps. Aurorin solves both of these problems by being a CAD software built from the ground up on a modern tech stack with AI at its heart. Building the CAD kernel lets us fully leverage AI while modernizing execution speed. Almost all existing CAD software (Solidworks, NX, Creo, Catia, Fusion 360, Onshape etc) use the same couple of underlying CAD kernels built in the 80's. It's common for these programs to take 4 hours to open a file. Aurorin uses a custom parametric and B-Rep driven CAD Kernel built to take full advantage of modern CPUs and GPUs and be AI native.

Score every batch against your own thesis
GPAgent's sourcing agent reads every company in a batch, scores each one against your fund's thesis in a private workspace, and lines up the founders worth meeting before Demo Day. You decide who to contact. Your scores, notes, and pipeline never appear on these pages.
