About Hypercubic

Hypercubic is an AI-native platform 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
