FAQ
Asked, answered,
on the record.
The questions everyone asks — answered plainly, no hedging. If yours isn’t here, the guided flow takes three taps.
the company
What is PalmDigitalz?
A mainframe-modernization company founded in 2020, headquartered in Chennai, India, and bootstrapped. We build the only target-agnostic modernization platform: four engines — Palm 360, Palm Key, Palm Ark, Palm Ray — that take mainframe estates to open microservices or packaged ERP, deterministically and with full source lineage.
Who leads PalmDigitalz?
Jeyaraj Jeba Elizabeth, CEO, and Jos Jacinth, CTO. No outside capital — the company is bootstrapped, which means our roadmap answers to customers, not investors. More on the founders page.
What recognition has PalmDigitalz received?
In the MarketsandMarkets 2026 Mainframe Modernization report, PalmDigitalz is categorized as a Pervasive player and ranked #2 worldwide in product strength — second only to IBM. The full fact sheet lives on the press page.
the platform
What does the platform actually do?
Four engines, one path: Palm 360 rationalizes the estate, Palm Key maps every dependency, Palm Ark extracts the business rules with receipts, and Palm Ray forward-engineers them into the architecture you chose.
How accurate is the business-rule extraction?
Up to ~95% on PalmBench, our reproducible benchmark, with 100% source lineage — against roughly 30% for generic LLMs asked the same question on the same program. We'll reproduce the run on your code, inside your perimeter. See Gazelle and PalmBench.
What does “deterministic” mean here?
Same input, same output — every time. Ask Ark three times and you get one artifact with one content hash, not three different answers. That's what lets auditors sign off. The full framework is written up in Near-deterministic by design.
Does our code leave our environment?
No. Everything runs inside your perimeter — on-premises and air-gapped deployments included. Nothing leaves your environment, ever. Details on the security page.
Which modernization targets are supported?
Open Python microservices, or packaged ERP — Oracle Fusion, SAP, Workday, Salesforce. Target-agnostic by design: the destination is your architects’ decision, not the tooling’s constraint.
Can’t a generic LLM do this instead?
On large programs generic models lose rules to context collapse, hallucinate plausible-but-absent logic, answer differently on every run, and attach no lineage. Same benchmark, same program: ~30% for generic LLMs vs up to ~95% for Ark. The full matchup is at vs Generic LLMs.
working with us
How does an engagement start?
Write to us through the guided flow. A real person replies, there’s one scoping call, then a written proposal for a paid proof of concept — typically your hardest program, 4–6 weeks, evidence at the end.
How much does mainframe modernization cost?
It depends on estate size, target, and how much scope can be retired first — Palm Key’s dead-code report typically removes 33–40% before anything is priced. We publish the full cost anatomy and an open exit calculator so you can model your numbers before talking to anyone.
people & community
Do I need a degree or résumé to join?
No. We don’t run interviews at all. The Crucible is an invitation event: builders work on real legacy estates, reviewers read the work — not the résumé — and the best leave with a return offer.
What is Palm Neh?
The global community of the most ambitious architects, engineers, and leaders in mainframe and enterprise modernization. Free, and by application — the bar is seriousness, not seniority. Read the charter.
What is The Mainframe Empire?
A program produced by PalmDigitalz — conversations with the people who run, open, and leave the world’s most important legacy systems. Episode 01 premiered July 18, 2026, 8:00 PM IST. Enter the Empire.
