Is AI a silver bullet for mainframe modernization?
The Software Dark Factory: modernizing legacy systems with no humans in the loop
A software dark factory writes and verifies software without a human in the loop — no one authoring the code, no one reviewing it.

Mainframe modernization is a verification problem
Mainframe modernization is a verification problem
We had a general-purpose LLM and an Imogen workflow each rewrite the same mainframe job in Java. Both versions compile and run; only one is verifiable.
“Having the ability to use tools like Imogen® to automate testing and verify there is no difference in outputs quickly and efficiently with a high degree of confidence, there is just a ton of value in that. We spend all of our time on tech refreshes and it kills us”
⎯ Fortune 20 Automotive Company
“What was originally scoped as an 18-month effort was delivered in approximately five months.”

At Google Cloud Next 2026, SulAmérica talks about how Imogen helped their mainframe migration to GCP.

“We spent years working around the constraints of an outdated system. Now, we have one that moves with us, not against us. With Mechanical Orchard’s approach, we’re set up to modernize faster while maintaining the same level of precision and quality. That’s a real game-changer.”
⎯ Fortune 500 Retailer
“Mechanical Orchard didn’t just modernize our system—they proved that mainframe rewrites can be done safely, without disruption. Their methodology ensures the highest quality, which is what truly matters.”
⎯ Fortune 500 Retailer
“I've been very impressed with the amount of rigor that Mechanical Orchard brought to this engagement.”
⎯ Fortune 100 Healthcare Company
“I'm really impressed with what the team was able to accomplish in a short number of weeks.”

Your mainframe works. And that's what makes modernizing it so tricky. With most approaches, you only discover what isn't working once everything is already built.
Imogen rewrites legacy systems into modern code while continuously verifying that nothing breaks, so risk doesn’t accumulate in the first place.
The unlock? Automating not just code generation, but verification, too.

Dharmesh Mistry has spent four decades building banking technology — at Lloyds, NatWest, and as chief digital officer of Temenos, where he had a hand in the UK's first mobile banking app. His new book, The Intelligent Ledger, argues banking is nearing its own version of a smartphone moment.
Mechanical Orchard Achieves ISO/IEC 27001:2022 Certification
Mechanical Orchard has achieved ISO/IEC 27001:2022 certification, following an audit of our Information Security Management System (ISMS) by Schellman, an independent, ANAB-accredited certification body.
The Cutover Checklist
A modernization program can be on time, on budget, staffed by people you trust, and you might still wonder: is this going to work?
Pane relief
Every dollar of AI ROI an enterprise is chasing runs through that brittle, Winchester Mystery House of a system, that same one keeping vital organizational organs pulsing and alive.
