For organisations
Get your team mainframe-ready, before they touch a real system.
A safe, browser-based z/OS lab for banks, consultancies, apprenticeship providers, and universities. No access delays, no infrastructure, and no risk to production.
9 role-based tracks and 228 lessons, taking your team from a first command through JCL, COBOL, DB2, CICS, RACF and REXX. See the curriculum
Live in days, not quarters
Your team could be up and running within days.
Nothing to install, nothing to provision, no infrastructure to stand up. The day your team has access is the day they start learning.
Onboarding onto the mainframe is slow and expensive.
Every week a new hire cannot get started is a week of cost with no output, and a week of a senior engineer's time at risk.
The cost today
A senior mainframe engineer costs roughly £700 a day. A week teaching the fundamentals is about £3,500 of their time, spent off the systems only they can run.
One expert, one small group, one week at a time. It pulls your scarcest people off the work only they can do.
The risk
The workforce that maintains these systems is retiring. Every year you do not build the next generation, the knowledge gap widens and the systems get harder to support.
A low-friction way to build a pipeline of people who understand the mainframe is workforce insurance.
Everything a training team needs.
One login, guided cohorts, and the controls to see real progress.
Zero infrastructure
Nothing to provision, install, or maintain. There's no lab to stand up before your team can start.
Cohorts and assignments
Group your learners, set a path, and keep everyone moving through the same guided work.
Progress and reporting
See where every learner is at a glance, so training teams can measure real progress.
Simulated and safe
Everything is simulated. There's no real system to break, and no data to put at risk.
Scrollable, drag to see it all
Live in a day, not a quarter.
Invite your team
Add your learners and set them on the guided ZedBank path.
They sign in and start
One login drops each learner into the lab. Nothing to install.
You track progress
Follow cohort progress and see who's ready, all from one place.
Founding partner
We're taking on a small number of founding organisations.
Mainframe101 is in private beta. Come in now and your team learns on it while you help decide what gets built next.
A direct line to the team
You talk to the people building it, not a support queue.
Your priorities shape the roadmap
Tell us what your team needs next and it goes to the top of the list.
Hands-on onboarding
We set your first cohort up with you, rather than handing you a help doc.
Early access
Your team is working in the lab before it opens up more widely.
Let's talk about your team.
Tell us how many people you need to train and what they do. We'll come back to you within one working day and walk you through it. No commitment, and no sales process to sit through.
