David Jenyns

The Guy Who Sold the
Melbourne Cricket Ground

Three businesses built and exited. Two bestselling books.
One mission: free every business owner from the daily grind.

From Rock & Roll to
Systems Thinking

David's entrepreneurial journey started in his early twenties — when he convinced someone to buy Australia's most beloved sporting venue, the Melbourne Cricket Ground. (Yes, really. It's a long story. Ask him about it.)

The day David sold the Melbourne Cricket Ground.

That early hustle set the tone for everything that followed. A stock market education business designing trading systems. A rock 'n' roll clothing store called Planet 13. A digital agency, Melbourne SEO Services, that grew into one of Australia's most trusted.

Every business taught the same lesson: the founder is always the bottleneck.

It didn't matter how good the product was or how talented the team. If the business couldn't run without David in the room, it wasn't really a business. It was a job with a fancy title.

A 7 AM Email That
Changed Everything

It was 7 am in Melbourne when an email arrived from someone called Luz Delia Gerber.

The name wasn't familiar. But a certain Michael E. Gerber — author of the E-Myth series, the man who coined "work ON your business, not IN it" — very much was.

Gerber, at eighty years old, was preparing to launch his twenty-ninth book. His first self-published title. And after watching David's videos, Luz Delia had decided: David was the person to lead the project.

David with Michael E. Gerber — the man who taught the world to work ON the business.

There was one catch. It would take sixty-plus hours a week. For three months. David would have to walk away from his own business entirely.

Two years earlier, he would have had to say no. He was too enmeshed in the daily operations. Without him, there was no business.

But this time was different. David had spent those two years building systems — documenting processes, training his team, removing himself from every bottleneck. His business didn't just survive his three-month absence. It barely noticed.

Gerber's book became his first Amazon bestseller within twenty-four hours of launch. David was invited to Carlsbad, California to celebrate, and then asked to facilitate a mastermind group dedicated to Gerber's legacy.

The irony wasn't lost on anyone: the man who taught the world to work ON the business — had been helped by someone who'd actually done it.

Building SYSTEMology

That experience crystallised everything. David had found a repeatable framework for freeing business owners from their own operations — and he couldn't keep it to himself.

SYSTEMology was born. Not as theory, but as a battle-tested methodology built from real exits, real businesses, and real results.

David Jenyns — I love systems

Since then, David has:

  • Written three booksSYSTEMology, The Systems Champion, and Authority Content — with over 100,000 copies in circulation
  • Built systemHUB — a SaaS platform that helps business owners document and manage their systems
  • Trained a global network of certified SYSTEMologists who implement the framework inside businesses worldwide
  • Spoken on stages from TEDx to industry conferences across Australia and internationally
  • Hosted 500+ episodes of the Business Processes Simplified podcast
  • Impacted 100,000+ business owners through books, training, workshops, and online content

The thread through all of it: ordinary people, plus well-designed systems, produce extraordinary results.

Speaking, writing, and helping business owners find freedom through systems

The Hills He'll Die On

Freedom comes from systems, not hustle.
Business owners should build assets, not jobs.
Simple beats perfect. Every time.
Systems enable creativity — they don't kill it.
The right Systems Champion beats experience.
Your business isn't broken — your systems are.
Start with one. Then build from there.
The true value of a business is its systems.
"Businesses don't fail because people aren't working hard enough — they fail because their systems aren't. Systems are how freedom, scale, and legacy are built."

The Person Behind
the Systems

Above everything else, David's a dad, a husband, and someone who tries to be a good human. That's the whole point of building systems — to have the freedom to be present for the things that actually matter.

When he's not helping business owners escape the daily grind, you'll find him on the Brazilian Jiu-Jitsu mats, tearing down mountain bike trails, travelling with his family, or chasing whatever gets the adrenaline pumping. A bit of an adrenaline junkie, if he's honest.
