Hopper

Mainframe developers, listen up. Your keyboards are about to become obsolete.

Hopper is the first agentic development environment built specifically for mainframe and COBOL—the programming language that's been running banks, insurance companies, and government systems since the 1960s. Yes, THAT COBOL. The one everyone jokes about but nobody wants to touch because there's no money in it and all the developers who know it are retiring.

Until now.

Hopper brings AI agents to the stodgiest software ecosystem on the planet. It writes COBOL code, debugs legacy systems, and handles the mind-numbing maintenance work that's been driving developers insane for decades. While everyone's fighting over AI coding tools for React and Python, Hopper saw the $3 trillion mainframe industry and said "someone should fix that." So they did.

The dirty secret of tech? Most of the world's financial infrastructure still runs on COBOL. We're talking trillions of dollars moving through systems written before your parents were born. There are millions of lines of COBOL code still in production and basically nobody left who understands it. Hopper is essentially building a time machine—not for people, but for code.

This is the most un-sexy product in AI right now and that's exactly why it might be the most important.
