Hypercubic

Hypercubic is an AI-native company focused on mainframe and COBOL modernization. The world's most important industries, including finance, government, energy, insurance, manufacturing, airlines and retail, still depend on mainframe systems built in the 1970s and 80s. These systems run about 75% of the Fortune 500. Hypercubic builds domain-specific, agentic AI that can understand, reason about and rebuild these large legacy applications. Its work combines program analysis, knowledge extraction and agentic systems. The company is backed by top investors and already works with some of the largest organizations in the world. So far, its enterprise pipeline has come from founder-led sales, and demand from upper-enterprise buyers such as banks is strong. Large contracts are worth six to seven figures and usually start as pilots before becoming paid deployments. Hypercubic is led by founder and CEO Sai Gurrapu, an engineer by background. It is a small, highly technical team of about seven based in San Francisco. The team works in person, moves fast and values ownership, high agency and zero-to-one building.
