What People Say

2 client testimonials

“LeanZero worked with UBS on migrating their infrastructure from DC to cloud—a first for the bank in this space. Each step was uncharted territory, requiring careful navigation and precise execution. LeanZero did a magnificent job managing competing priorities and stakeholder demands. We threw ideas at them constantly—this didn't make their life any easier. they handled intense pressure with welcome calmness. 100% recommended. Excellent partner to work with.”

Sentinel Vault

Sentinel Vault: you cannot block an edit in Confluence, so we undo it instead

Forge gives you no veto over a Confluence save. Product events arrive after the change is already committed, which means a lock on Confluence content cannot prevent anything — it can only detect and restore. Here is what that constraint does to an app: why the restore has to ignore itself, why reverting the whole page is the wrong fix, and why a licence check in a protection app must fail open.

Cloud Migration

Jira automation rules do not migrate themselves

JCMA brings your rules to Cloud disabled and without their actors. Cloud-to-cloud brings nothing at all. Measured on a live Cloud site: the Rule Management API's 400s that name no field, the app-actor discovery our own runbook got wrong, and the scope ARI the API silently rewrites behind your back.

LeanZero Management: virtualising a 5,300-issue Gantt

A 5,300-issue plan put 94,920 nodes in the DOM. Windowing the rows took it to 2,115 — and left a second full-height layer that windowing does not touch.
