About Greg Cassar
I built the businesses, the investments, the life by design.
Now I help others build all three.
Greg Cassar. Growth Hacker. Marketer. Business Coach. Marketing Coach. Investing Coach. Philanthropist.
For 22 years I've been quietly engineering one of Australia's most unusual entrepreneur portfolios — a small group of companies doing up to $2M per month, a significant investment portfolio compounding in the background, and the lifestyle most "successful" founders fantasise about but never reach.
This page tells you how I got here, and why it matters for you.

02 — THE CUBICLE WASN'T THE PLAN
Before any of this, I was an IT Enterprise Architect in corporate.
Designing server infrastructure & networks for Government, banks & large institutions.
Stable. Respectable. Quietly suffocating.
In 2003 I started selling online — with time the side income had overtaken the salary. I handed in the resignation, and never looked back.
03 — THE MARKETER
Top 1% of marketers on the planet.
I spent the next seven years running a direct-response digital marketing agency. Traffic, conversion, profit — nothing else.
Across 350+ client businesses in the Agency and Mastermind, my team is responsible for over $500M in online sales, 2 million+ leads generated, $100M+ in paid traffic spend, and more than 400 split tests run.
Every framework I teach has been pressure-tested in real businesses, usually mine.

04 — THE GROWTH HACKER
Scaling a business as a formulaic recipe.
Most marketers can run an ad. Few can engineer a business to dominate its category.
Growth hacking a business to scale is a repeatable skill. I now partner with a small handful of global hero brands as their Growth Hacker — on revenue share or equity — to scale them into category leadership.
Skin in the game changes the math. And the outcomes.
05 — THE AI BUSINESS COACH
Scaling businesses systematically with AI.
In 2015 I launched The Collective Mastermind.
Over the next 8½ years, more than 150 Australian business owners walked through it. Some added $50M+ in additional sales. Almost every member doubled. Many tripled & more.
I paused The Collective during Covid. Then I rebuilt it from the ground up for the AI age — sharper, faster, more leverage. The members have a significant advantage over their competition because of access to information, sharper minds & speed of implementation.
The Collective is now Australia's highest-level mastermind for business owners ready to compound across all 8 pillars: AI, business, investing, marketing, sales, biohacking, mindset & EQ, and lifestyle by design.
06 — THE MARKETING COACH
Marketing is the lever. Profit is the proof.
Inside The Collective, marketing is my home turf.
Funnels, paid traffic, organic content, AI-driven systems, conversion optimisation, copy, offers — I've spent two decades obsessing over what actually moves the needle.
When members ship a campaign, they ship one engineered with the help of someone with 23 years of receipts. Advanced marketing knowledge combined with state-of-the-art vibe coding and AI tools creates an unlimited opportunities & advantages.
07 — THE INVESTING COACH
Make it. Keep it. Multiply it.
Most business owners are asset-rich and cash-trapped. I was too — until I learned to invest. Real wealth & freedom comes when you have both cash flow and a large golden goose nest egg.
Today I run a multi-million-dollar portfolio. More importantly, I teach my members the exact strategies I'm doing — many of whom now generate investment returns that rival their business profits.
Earning is one skill. Compounding is another. You need both to win the long game. Business plus investing is like 1 + 1 = 3.
$500M+
For two decades I've reinvested over a quarter of a million dollars into my own learning — mentors, masterminds, conferences, the highest-level rooms in the world.
The best in AI, marketing, sales, conversion, eCommerce, financial IQ, longevity, mindset & health.
What I teach is not theory. It's a curated playbook, drawn from the people quietly winning at the highest level.
09 — WORK SMART, PLAY HARD
The whole point was always the life.
I live in sub-tropical Byron Bay. I surf every morning. I ride eBikes & go on adventures. Some say I'm in the ocean more than I'm at the desk.
Work-life balance isn't a phrase I sell. It's the 'build a great life resume' architecture I've spent 20 years engineering — and now teach others how to build for themselves.
What you see is what you get. No persona. No surprises.
10 — PHILANTHROPIST
Make money. Make a ripple.
Wealth without contribution lacks some sense of purpose higher than ones self.
In recent years we have planted 25,000 trees, and are now focussed on our own charity efforts to help women and children who need it most with food, shelter and safety.
I'm also teaching others how I've set this up to be self-funding and passing the lessons on to the next generation by having my children involved as directors, to learn and to make a difference.
The Mission
You don't have to choose between wealth and freedom.
Most successful entrepreneurs I meet are running a business that runs them. Bigger revenue, smaller life.
I've been on both sides. I know which one wins.
The Collective exists for the rare business owner ready to engineer it all — the business, the wealth, the health, the mindset, and the lifestyle by design.
If that's you, let's talk.
