What Hypercubic does

Hypercubic is an AI-native infrastructure for mainframe operations and modernization. We help enterprises understand and modernize their mission-critical legacy systems. About 70% of the Fortune 500 companies still rely on them to run their core business applications in banking, insurance, telecom, airlines, retail, and more. These systems, originally built in the 1960s - 90s, still power trillions in global infrastructure today but have become increasingly opaque as original developers retire or leave the workforce. We are pioneering a new class of intelligence capable of understanding, reasoning about, and rebuilding the world’s foundational infrastructure. Learn more at hypercubic.ai

AI to maintain and modernize COBOL

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

We're building an AI-native tool that helps enterprises understand and modernize their COBOL-based mainframe systems. Our product reads through decades-old legacy code to map and reason about how core business logic works. It makes the infrastructure less opaque as original developers retire, enabling companies in banking, insurance, telecom, and other sectors to safely update and maintain these mission-critical systems.

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.

San Francisco has the best access to technical talent, potential customers in finance and enterprise, and YC itself is here. That proximity makes the most sense as we scale.
