What Topological does

Topological is developing physics-based foundation models for CAD optimization. We help hardware teams iterate at the same speed that software teams do. Our technology is accelerating the engineering workflow with AI and scales design and optimization to identify the ideal designs for complex problems given their physical constraints with enhanced speed and performance. Our first model, UToP-v1, is a SOTA topology optimization model that understands physics, geometry, and manufacturability. It can generate the most efficient design given a problem’s physical requirements. It has <5% compliance error and is 1930x faster than current methods. We're reimagining mechanical engineering and computational design with precision spatial AI.

Physics-based foundation models for CAD optimization

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

We are building physics-based foundation models like UToP-v1 that optimize CAD designs directly by understanding physical constraints, geometry, and manufacturability. Our model generates efficient engineering designs much faster than current topology optimization methods, helping hardware teams iterate as quickly as software teams do.

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

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

Explain your decision regarding location.

Being in San Francisco puts us at the center of AI and hardware innovation and close to early customers in the engineering and design space. It helps us recruit and stay connected to industry trends.

Frequently Asked Questions

Is this the real Topological YC application?

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