What Aurorin CAD does

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.

What is your company going to make? Please describe your product and what it does or will do.

We are building a CAD software from the ground up with AI integrated at its core. Our product replaces decades-old CAD kernels with a custom parametric and B-Rep driven engine that runs much faster and allows engineers to design without tedious manual steps. It's built specifically for mechanical engineers who lose time waiting for slow software and repetitive processes.

Where do you live now, and where would the company be based after YC?

I live in San Francisco and the company will be based here after YC.

Explain your decision regarding location.

San Francisco is where I am now and it's the best place to build a deep engineering software company, with access to talent and potential customers nearby.

Frequently Asked Questions

Is this the real Aurorin CAD YC application?

No. Y Combinator keeps submitted applications private. This is a reconstruction: the real YC form questions, answered from Aurorin CAD's public data (launch notes, founder backgrounds, product description). It shows how a company like Aurorin CAD would present itself to YC, not the text they submitted.
