About Hypercubic
Summary
Hypercubic builds an agentic AI platform that helps large enterprises maintain and modernize COBOL codebases and mainframe systems. Its tools convert opaque legacy code into searchable documentation, capture expert debugging workflows as digital twins, and provide a natural-language terminal for mainframe operations. The platform replaces manual archaeology of decades-old systems and fills the gap left as the original developers who built and understood them retire.
Go-to-market
Hypercubic sells to enterprise and government mainframe teams in banking, insurance, telecom, airlines, and retail, with buyers engaging through a demo request on the website.
From the Y Combinator listing
AI to maintain and modernize COBOL.
Hypercubic is an AI-native maintenance and modernization platform for COBOL and mainframes. We help enterprises understand and preserve 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're laying the foundation to autonomously maintain and modernize these legacy systems to future-proof the backbone of the global economy. Learn more at hypercubic.ai
