Mainframe systems are often rigid and costly to maintain. Banks face mounting complexity, compliance pressures, and constraints—yet modernization efforts often risk high-profile failure.
Mechanical Orchard’s Imogen modernization platform rewrites aging banking applications into modern, cloud-ready systems—without breaking what already works. Our incremental and speedy process helps banks move faster, and avoids the long delays and failures of traditional modernization approaches.
The conventional modernization model relies on large teams, a patchwork of vendor tools, some of which use AI, and a sequence of phases — analysis, code transpilation, then a long, uncertain stretch of integration and regression testing. After what are often years of effort, success hinges on a single, high-stakes moment to see if everything actually works. Most of the time, it doesn't.
Instead of focusing on code, Imogen captures how individual workloads actually behave — through real data flows — and rewrites that behavior into modern code. By creating a rapid loop of generation and validation against actual production data as each workload is rewritten, Imogen eliminates the long, uncertain integration phase that has defined — and derailed — conventional modernization efforts.
Rather than applying generative AI directly to code translation, Imogen first builds a precise behavioral specification from the running system, then applies a closed loop of rapid code generation and verification against those specifications. The result is software that is audit-quality, idiomatic, and genuinely ready for what comes next — not just syntactically modern.
While the methodology works for any legacy system, our data capture technology is optimized to automate the modernization process for the following mainframe technologies.
Banks regain the flexibility to adapt, launch new products, and improve operations without the often fraught and unpredictable big, "digital transformation" initiatives.
At the London book launch for the latest book from Leda Glyptis, Ph.D., leaders on the front lines of banking transformation share their views.

We believe that every company deserves to realize their vision, free of constraints from the past. Our team's technology, and experience can help them move into this evolving version safely, reliably, fearlessly.
