How William Erbey’s ideas become reality

How the entrepreneur, philanthropist and inventor Bill Erbey applies his philosophy to machines and medicine.

It’s rare to meet a serial entrepreneur who founded six multibillion-dollar publicly-listed companies, who applies mathematical and statistical concepts to his business projects. When questioned about their success, others choose happenstance over conspiracy; for William Erbey, it’s the application of math and statistics each time.

“For the last 50 years I have applied those concepts to my businesses wherever possible-my goal is to devise products that provide greater value to the customer, that can be produced at a lower cost, so I can compete on price if need be,” said Bill. In his case those projects almost always involved a technological solution grounded in math and statistics.

Bill has invented a patent-pending control system for generators and electric motors. In simple terms, it reduces the heat generated by half, and increases the engine’s efficiency by about 8%. The Kira motor technology will radically enhance the modern electric motor by increasing its driving range, which will significantly increase electric vehicles mass adoption.

A recent investment close to Bill’s heart is in the futuristic area of medical devices, and more specifically, in the medical technology associated with kidney failure.

“Of course, there’s obviously math and analytics involved here, but not the same type. What are the three biggest medical spends? – Kidney, cancer and cardiac. Do you realise that medical treatment involving kidneys in the United States will represent a $1.4 trillion spend by 2030, so it’s a massive issue”, he said in a recent RealVision interview.

What interested Bill specifically was John Erbey’s idea, changing the whole way of thinking about how one deals with kidney problems.

In essence most of today’s solutions are all about pushing fluid through the kidney, or “renal preload”. “Today, we try and put more fluid through the system, and we use drugs as well”.

For Bill it was the way the fledgling company is looking at the whole issue from outside the box. “The reason I invested in the company, besides him being my nephew” he smiled “was the fact that his solution was so elegant. “Why didn’t anybody think of looking at the problem in that way before? Why do you push fluid through the kidney-why wouldn’t you pull fluid through it instead? It is a very elegant and simple solution to a major problem”.

According to the Strataca Systems’ official website, the company believes ‘expensive medical problems require effective solutions’. Few problems are as large or as expensive as acute decompensated heart failure, which leads over 1 million hospital admissions in the USA each year. The primary reason for hospitalisation is congestion-fluid overload-which leads to shortness of breath’. Since the kidneys are responsible for fluid management, as renal function is compromised, the morbidity, mortality and costs for these patients rise. The company is developing patented technology to improve urine output and decrease congestion.

The problem that is being addressed is hugely significant in numbers alone; between eight and 10% of the world’s population suffers from cardiorenal syndrome-that is, kidney failure. In real terms that’s 12 Americans dying each day.

What separates Bill from many investors, is that he really is interested in the minute detail of how the product or service works. He’s a man who really cares about making people’s lives better – it’s his key to success. He wanted to know exactly how the medical device worked and what was the thought behind it. And he’s therefore able to explain the details.

“By pushing liquid through the kidney, you put more pressure on it-the kidney itself is in a semirigid sack, so it actually starts deteriorating the kidney function. So it was interesting when my nephew explained to me exactly how they deal with the problem today. It was like my understanding of the Internet”. Today, the cure for this ‘congestion’, rather like the cure for the increased Internet congestion, is again trying to push more stuff through the system. The kidney pushes back and basically nothing happens. John spent four months thinking about why nobody had ever thought about the problem in his way. So what he does is use negative pressure to pull the urine out of the kidney. It’s already through the animal testing stage and is now going through human testing”.

And like his other projects combining investment with innovation, machinery, conservation, Internet streaming, Bill believes that this will ultimately help people to not have to go on dialysis.

“It’s a horrible thing and certainly significantly truncates one’s life expectancy. As I said it’s a $1.4 trillion market which is amazing. And that figure represents the US alone. Globally it’s probably closer to $3 trillion. So it’s a massive market, and he has a very strong patented protection around the idea”.

It’s no wonder that they call Bill Erbey a Renaissance man; looking at his myriad of inventions and investments, he certainly seems to exemplify the expression “the man with the Midas touch”. Watch this space.

High Volume, High Value: The Business Logic Behind Black Banx’s Growth

Matthew Wiles

In fintech, success no longer hinges on legacy prestige or brick-and-mortar branches—it’s about speed, scale, and precision. Black Banx, under the leadership of founder and CEO Michael Gastauer, has exemplified this model, turning its high-volume approach into high-value results.

The company’s Q1 2025 performance tells the story: $1.6 billion in pre-tax profit, $4.3 billion in revenue, and 9 million new customers added, bringing its total customer base to 78 million across 180+ countries.

But behind the numbers lies a carefully calibrated business model built for exponential growth. Here’s how Black Banx’s strategy of scale is redefining what profitable banking looks like in the digital age.

Scaling at Speed: Why Volume Matters

Unlike traditional banks, which often focus on deepening relationships with a limited set of customers, Black Banx thrives on breadth and transactional frequency. Its digital infrastructure supports onboarding millions of users instantly, with zero physical presence required. Customers can open accounts within minutes and transact across 28 fiat currencies and 2 cryptocurrencies (Bitcoin and Ethereum) from anywhere in the world.

Each customer interaction—whether it’s a cross-border transfer, crypto exchange, or FX transaction—feeds directly into Black Banx’s revenue engine. At scale, these micro-interactions yield macro results.

Real-Time, Global Payments at the Core

One of Black Banx’s most powerful value propositions is real-time cross-border payments. By enabling instant fund transfers across currencies and countries, the platform removes the frictions associated with SWIFT-based systems and legacy banking networks.

This service, used by individuals and businesses alike, generates:

Volume-based revenue from transaction fees
Exchange spreads on currency conversion
Premium service income from business clients managing international payroll or vendor payments

With operations in underserved regions like Africa, South Asia, and Latin America, Black Banx is not only increasing volume—it’s tapping into fast-growing financial ecosystems overlooked by legacy banks.

The Flywheel Effect of Crypto Integration

Crypto capabilities have added another dimension to the company’s high-volume model. As of Q1 2025, 20% of all Black Banx transactions involved cryptocurrency, including:

Crypto-to-fiat and fiat-to-crypto exchanges
Crypto deposits and withdrawals
Payments using Bitcoin or Ethereum

The crypto integration attracts both retail users and blockchain-native businesses, enabling them to:

Access traditional banking rails
Convert assets seamlessly
Operate with lower transaction fees than those found in standard financial systems

By being one of the few regulated platforms offering full banking and crypto support, Black Banx is monetizing the convergence of two financial worlds.

Optimized for Operational Efficiency

High volume is only profitable when costs are contained—and Black Banx has engineered its operations to be lean from day one. With a cost-to-income ratio of just 63% in Q1 2025, it operates significantly more efficiently than most global banks.

Key enablers of this cost efficiency include:

AI-driven compliance and customer support
Cloud-native architecture
Automated onboarding and KYC processes
Digital-only servicing without expensive physical infrastructure

The outcome is a platform that not only scales, but does so without sacrificing margin—each new customer contributes to profit rather than diluting it.

Business Clients: The Value Multiplier

While Black Banx’s massive customer base is largely consumer-driven, its business clients are high-value accelerators. From SMEs and startups to crypto firms and global freelancers, businesses use Black Banx for:

International transactions
Multi-currency payroll
Crypto-fiat settlements
Supplier payments and invoicing

These clients tend to:

Transact more frequently
Use a broader range of services
Generate significantly higher revenue per user

Moreover, Black Banx’s API integrations and tailored enterprise solutions lock in these clients for the long term, reinforcing predictable and scalable growth.

Monetizing the Ecosystem, Not Just the Account

The genius of Black Banx’s model is that it monetizes not just accounts, but entire customer journeys. A user might:

Onboard in minutes
Deposit funds from a crypto wallet
Exchange currencies
Pay an overseas vendor
Withdraw to a local bank account

Each of these actions touches a different monetization lever—FX spread, transaction fee, crypto conversion, or premium service charge. With 78 million customers doing variations of this at global scale, the cumulative financial impact becomes immense.

Strategic Expansion, Not Blind Growth

Unlike many fintechs that chase customer acquisition without a clear monetization path, Black Banx aligns its growth with strategic market opportunities. Its expansion into underbanked and high-demand markets ensures that:

Customer acquisition costs stay low
Services meet genuine needs (e.g., cross-border income, crypto access)
Revenue per user grows over time

It’s not just about acquiring more customers—it’s about acquiring the right customers, in the right markets, with the right needs.

The Future Belongs to Scalable Banking

Black Banx’s ability to transform high-volume engagement into high-value profitability is more than just a fintech success—it’s a signal of what the future of banking looks like. In a world where agility, efficiency, and inclusion define competitive advantage, Black Banx has created a blueprint for digital banking dominance.

With $1.6 billion in quarterly profit, nearly 80 million users, and services that span the globe and the blockchain, the company is no longer just scaling—it’s compounding. Each new user, each transaction, and each feature builds upon the last.

This is not the story of a bank growing.

This is the story of a bank accelerating.
