Design a chip in minutes

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

We've built a chip design tool that uses physics-informed models accelerated by GPUs to run simulations up to 700 times faster than legacy software. This lets engineers test and optimize chip designs in minutes instead of weeks and makes AI-driven optimization practical for chip development.

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

We live in San Francisco, CA, and the company will be based here after YC.

Explain your decision regarding location.

We live in San Francisco because it puts us close to chip design professionals and potential customers, and it's a natural place for startups in hardware and software to grow.
