5M Leadership Institute | Executive Masterclasses
One Day.
Lasting Change.
In-person and online masterclasses built on the 5M Unbreakable and Stitch In Time frameworks.

Each masterclass is a curated selection of two domains from the 5M suite - taught with intellectual rigour, applied to your real situation, and producing instruments you use the next day. Not a seminar. A working session.

Why a 5M Masterclass
Designed for leaders who read the research and still need to act on Monday.
Every masterclass produces at least one completed governance instrument. Not notes. An instrument.
📊
Diagnostic First
Every domain begins with a scored diagnostic that tells you exactly where you are before you build anything. You are not receiving information. You are solving your own problem.
🏗
Built in Session
You leave with a completed instrument for your organisation - a Core Map, a MOAT Stack, a Mandate Charter. Built on your real data. Ready to use the next morning.
👥
The Back Room Hour
From 4 to 5pm, participants share what they built. Structured tool-sharing before open networking. You leave having seen how eight other leaders solved the same problem in their organisation.
