Who is Greg Cassar?
Greg Cassar is an Australian business and investing coach who built a small portfolio of companies turning over up to $2M per month, alongside a multi-million-dollar investment portfolio compounding outside those businesses. He describes himself as a growth hacker, marketer, business coach, investing coach and philanthropist.
He didn't start there. Greg began his career as an IT Enterprise Architect in corporate Australia, designing server infrastructure and networks for government, banks and large institutions. Stable, respectable — and, in his words, “quietly suffocating.” In 2003 he started selling online on the side. When the side income overtook the salary, he resigned and never looked back.
What is Greg Cassar known for?
Greg is best known as one of Australia's most credentialled direct-response marketers and as the founder of The Collective Mastermind. For roughly seven years he ran a direct-response digital marketing agency focused on one thing: traffic, conversion and profit. Across his agency and mastermind work, his teams are responsible for more than $500M in online sales, 2 million+ leads, $100M+ in paid traffic spend and over 400 split tests.
Today he partners with a small handful of global brands as their growth hacker — on revenue share or equity — and teaches established business owners how to engineer growth as a repeatable system rather than a lucky break.
“Skin in the game changes the math. And the outcomes.”
Why did Greg Cassar create Business Invest Freedom?
Business Invest Freedom exists because most business owners are asset-rich and cash-trapped — brilliant at making money, never taught how to keep it or multiply it. Greg lived that gap himself before he learned to invest.
The principle behind everything on this site is simple: make it, keep it, multiply it. Business cash flow first. Then tax and structure. Then exponential, long-term investing. Earning is one skill; compounding is another — and you need both to be genuinely free.
Business Invest Freedom is where Greg shares the free tools and thinking that come out of that philosophy — including the Retirement Gap Calculator and his upcoming book — no application, no cost.

What does Greg Cassar teach?
Greg teaches a full-stack approach to wealth rather than chasing revenue alone. His work spans business growth, marketing, investing, AI, and lifestyle design — the idea being that you compound across all of them instead of optimising one and neglecting the rest.
A few of the named ideas he's known for:
- Make It. Keep It. Multiply It. — a three-stage wealth philosophy: business cash flow, then tax and structure, then exponential investing across equities, property and crypto.
- The Profit Triad — the three levers that grow any business: get more customers, get them to spend more, and get them to come back.
- Lifestyle by Design — building a business that gives you your life back, engineered rather than stumbled into.
He goes deeper on all of this inside The Collective Mastermind, but the core thinking shows up across the free resources here.
What's Greg's track record?
Greg has spent over two decades building, breaking and rebuilding businesses — and reinvested more than a quarter of a million dollars into his own learning along the way: mentors, masterminds and the highest-level rooms in the world.
He launched The Collective Mastermind in 2015. Over the following years more than 150 Australian business owners came through it; many doubled, some tripled, and a number added $50M+ in additional sales. He paused it during Covid, then rebuilt it from the ground up for the AI age. What he teaches isn't theory — it's a pressure-tested playbook drawn from the people quietly winning at the highest level.
Who is Greg Cassar outside of business?
Greg lives in sub-tropical Byron Bay, surfs most mornings, and rides eBikes on adventures — “some say I'm in the ocean more than I'm at the desk.” Work-life balance isn't a phrase he sells; it's the architecture he's spent twenty years engineering and now teaches others to build.
He's also a philanthropist. In recent years his efforts have included planting 25,000+ trees and building a charity focused on women and children who need food, shelter and safety — with his own children involved as directors so the work passes to the next generation.
“Make money. Make a ripple.”
