The kubus scheme remains one of South Africa’s most iconic scams—a get-rich-quick operation that promised wealth, delivered buzz, and collapsed under its own weight. It wasn’t just a typical pyramid trick; it was a national sensation. People didn’t just invest—they believed.
Kobus Jonker, the mastermind behind the kubus scheme, didn’t operate in the shadows. He went big. Public. Loud. And for a while, it worked. Thousands fell for it. Millions were moved. But like every financial fantasy built on promises, it couldn’t last.
The Rise of the Kubus Scheme
In the 1980s, the kubus scheme burst onto the scene with a strange but seductive business model. Participants were told they could make serious profits by producing and selling a mysterious milk culture—called “kubus”—used in manufacturing health products. Investors bought starter kits with milk cultures and were promised that the company would buy back the fermented product at a high price.
It sounded unusual. But it sold hope. The barrier to entry was low. The returns were too good to ignore. And the word spread fast—especially in small towns, farms, and communities desperate for a financial breakthrough.
People didn’t ask hard questions. They brought in friends. They brought in family. They took out loans. The cycle of belief powered the whole machine.
Kobus Jonker: The Man Behind the Curtain
Kobus Jonker, the face of the kubus scheme, was charismatic and persuasive. He marketed his system as a revolutionary home business that could empower ordinary South Africans. And for a time, it did. Payouts were made. Word of mouth did the rest.
Jonker claimed scientific and ethical grounding. He deflected criticism. He used testimonials. He wore the suit of a businessman, but operated with the precision of a scam artist. By the time the authorities stepped in, the damage was widespread.
The kubus scheme became one of the most referenced fraud cases in the country’s history—an example of what happens when belief outpaces logic.
The Fallout: Legal Action and Legacy
Eventually, the inevitable happened. Investigations revealed that the scheme was unsustainable. No real market existed for the fermented product. There were no bulk buyers. The entire business model relied on new money feeding old promises.
The courts ruled against Jonker. The operation collapsed. Assets were seized. The people at the bottom—the true believers—lost everything.
But the kubus scheme didn’t disappear from public memory. It became a case study in how quickly a nation can be swept up in economic fantasy.
The Psychology of Belief
What made the kubus scheme so powerful? It wasn’t just the sales pitch. It was the climate. In a time of economic uncertainty and systemic inequality, the promise of self-driven wealth was irresistible. It gave people a sense of control. Of empowerment. Of potential.
Even as red flags appeared, many refused to walk away. Why? Because the returns felt real. And more importantly, everyone around them was doing it too.
This psychological dynamic—community pressure, hope, urgency—is at the core of most Ponzi models.
Other Notorious Scam Artists
While the kubus scheme takes center stage, South Africa has seen no shortage of similar fraudsters:
- Johan Steyn: Promised luxury real estate deals with guaranteed returns. Delivered losses and lawsuits.
- Jack Milne (PSC Guaranteed Growth): Duped sports stars and professionals by claiming consistent 15% monthly returns.
- Barry Tannenbaum: Pitched fake pharmaceutical deals. Made off with billions. Never faced trial in South Africa.
- Colin Davids: Used church connections to lure investors into pyramid schemes posing as foreign currency deals.
Each story was different. But the pattern was the same: charisma, urgency, fake success, and eventual collapse.
The Systemic Problem: Why Do These Schemes Keep Working?
The kubus scheme was not a one-time fluke. It was a symptom of deeper issues—financial desperation, lack of education, weak regulatory enforcement, and blind trust in authority figures.
Many victims don’t fall for the numbers. They fall for the messenger. The pitchman. The friend. The pastor. The family member. That’s what makes these scams so devastating—they erode trust at a personal level.
And once trust is broken, the fallout is emotional as much as it is financial.
Red Flags to Learn From
Every scheme has markers. These include:
- Promises of consistent high returns
- No clear explanation of how the business generates money
- Strong push to recruit others
- Fear-based urgency (“Act now or miss out”)
- Unregulated operators
The kubus scheme ticked nearly all of these boxes.
Regulatory Blind Spots
Despite advances in oversight, Ponzi schemes still find cracks in the system. Loopholes in company law, delays in prosecution, and low levels of financial literacy continue to create fertile ground for new scams.
Authorities often act after the damage is done. By then, the masterminds have moved assets, closed accounts, and vanished. Even when justice is served, victims rarely recover their losses.
The kubus scheme exposed these weaknesses decades ago. But the lessons weren’t fully learned.
The Power of Memory: Why Kubus Still Matters
Why write about the kubus scheme today? Because it’s still happening—just with new names, new products, and new platforms. From crypto scams to social media trading “gurus,” the model evolves, but the method stays the same.
Kubus reminds us that due diligence isn’t optional. That asking questions is healthy. That real businesses take time, offer risk, and don’t guarantee overnight wealth.
More than anything, it reminds us that belief can be dangerous—especially when weaponized for profit.

Final Word on the Kubus Scheme
The kubus scheme stands as one of South Africa’s earliest and most powerful examples of a national financial scam. It exposed how easily hope can be exploited. And how fast people can lose everything when trust is misplaced.
Kubus scheme victims were not greedy—they were hopeful. That’s why it’s critical to talk about these stories, learn from them, and make sure they’re never repeated.
