How VirtualZ Computing Is Using AI to Bridge Mainframe Data and Modern Cloud Apps in MN
VirtualZ Computing is a Minneapolis-based software company solving a problem most people don't know still exists: the world's biggest banks, insurers, retailers, and government agencies still run their core systems on IBM mainframes, and that data is notoriously hard to get out. Founded and led by Jeanne Glass, VirtualZ builds products like Lozen and Propelz that let modern applications read and write mainframe data in real time, without copying it, moving it, or rewriting decades of working code. It's a small Minnesota team taking on one of the least glamorous and most consequential problems in enterprise computing. The AI angle here is less about chatbots and more about plumbing. Every AI initiative at a large enterprise runs into the same wall — the model is only as good as the data it can reach, and the most valuable transactional data in a bank or a health insurer is sitting on a mainframe behind sixty years of custom integration. Companies like VirtualZ make that data reachable by live query instead of overnight batch extract, which is what turns a stale nightly snapshot into something an AI system can actually act on. Internally, teams building software at this level are also leaning hard on AI-assisted code analysis to understand legacy COBOL and PL/I, automated test generation for edge cases nobody documented, and AI support tooling that helps a lean team serve enterprise customers with enterprise expectations. The competitive advantage is speed and scope. Traditional approaches to mainframe modernization mean multi-year, multi-million-dollar migration projects that fail more often than anyone likes to admit. Making the existing system interoperable instead of replacing it turns a three-year program into a deployment, and it lets a Minnesota company with a focused team compete for accounts that would normally go to a global systems integrator. That's also why the business is a certified woman-owned company that shows up in rooms with Fortune 500 procureme
