The Leaders Column

The founder of SimplB, South Africa’s first regulated Bitcoin-only company, on why the real risk was never the price

James Caw bought his first Bitcoin in 2016, back when doing that in South Africa meant thin exchanges, clumsy sign-up forms, and almost nobody to ask for help. He worked it out the slow way. Then friends started asking. Then their friends’ friends. By 2020, what started as a favor had quietly become an informal OTC brokerage, and James had helped close to a thousand people buy Bitcoin, and just as importantly, get it off the exchange and into a wallet only they controlled.

That last part, buy, withdraw, hold the keys, is the thread running through everything he has built since.

From Side Hustle to South Africa’s First Regulated Bitcoin-Only Firm

While Bitcoin was still a side project, James’s day job was in mainstream financial services. By 2021, he was Head of Marketing for the largest international money transfer business based in Plettenberg Bay, working across foreign exchange treasury, cross-border payments, and compliance. It was, in hindsight, exactly the training he needed for what came next.

That same year, he sold his shareholding in the joint venture and went all in on Bitcoin as a full-time profession. Three years of structural work later, SimplB took its first client in September 2024 as South Africa’s first regulated Bitcoin-only company. James runs it from George on the Garden Route, and writes the SimplB Bitcoin Book Series in whatever gaps are left over.

Why Buying Bitcoin Was Never the Hard Part

James’s motivation for building SimplB did not come from a business plan. It came from watching things go wrong, sometimes in the news, sometimes to people he had personally helped years earlier.

“Those informal years taught me that buying Bitcoin is the easy part,” he says. “The hard parts are custody, inheritance, and paperwork.”

He describes sitting across from people holding serious amounts of Bitcoin with no record of where their keys were, nothing written down for a spouse, and no lawful way for an executor to access it if something happened to them.

“If they died on a Tuesday,” he says, “that Bitcoin was simply gone.”

Nobody local was solving the problem. Exchanges wanted volume. Advisers were not licensed for crypto assets, so they avoided the conversation entirely. The self-custody community had the right instincts but nothing a fiduciary could actually work with. Inheritance planning for Bitcoin barely existed in South Africa, and the risk of a brute-force attack on unsecured keys was very real.

“Filling it meant crossing the border,” James says, “getting licensed, building FICA-compliant onboarding, designing custody with no single point of failure, and treating inheritance as part of day one rather than something to sort out later.”

Bitcoin, he is quick to point out, was always a passion before it was a business. “I never planned to run a Bitcoin company. I wanted to fix the thing that kept costing people their savings, and a regulated firm was the only honest way to fix it for more than a handful of people at a time.”

What Makes SimplB Different

SimplB operates as a Juristic Representative of CAEP Asset Managers under the FSCA, making it South Africa’s first regulated Bitcoin-only company, and still the only regulated firm in the country built specifically around self-custody.

Three things set it apart. First, SimplB only handles Bitcoin. No altcoins, no tips, no hype, just full-service support from procurement through custody, entirely within regulated structures.

Second, every purchase ends in genuine self-custody. Clients buy through a named, FICA-compliant account, and the Bitcoin is withdrawn to a wallet they control. As holdings grow, most clients move into the SimplVault, a managed 2-of-3 multisig setup where the client holds two keys and SimplB holds one.

“No single point of failure,” James explains, “and nothing for a client to lose if we disappear tomorrow.”

Third, inheritance planning comes standard, not as an add-on. Recovery documents, instructions for heirs, and a briefing for the executor are built into onboarding for every vault client.

“Bitcoin with no recovery plan isn’t really secure,” he says. “It’s just lucky so far.”

SimplB’s clients range from individuals to family offices, companies, trusts, and fiduciaries, united by a single need: owning Bitcoin in a way they can explain clearly to an adviser, an executor, or a compliance officer, without risking the asset itself.

A Milestone That Looked Small and Wasn’t

Ask James about his most meaningful milestone, and he points to something that sounds modest on paper: onboarding SimplB’s first corporate client inside a fully regulated structure, with a managed multisig setup involving several parties.

Getting there required a licensed structure, FICA-compliant onboarding, the full multisig custody model, complete inheritance documentation, and patiently walking a third key holder who knew nothing about Bitcoin through understanding how to use it correctly.

Two other milestones sit alongside it. A practical self-custody guide he published has since been downloaded more than three thousand times. And his book, The Strategic Reserve, sold out twice in its first print run, published before the phrase entered mainstream political conversation.

The Losses That Shaped How He Runs the Firm

James is candid about the costly lessons behind SimplB’s design. Early in his own Bitcoin journey, poor financial education led him into an investment that turned out to be far riskier than it appeared, and he lost everything he had put in. Separately, he left funds with a friend who suffered a brute-force attack, and lost that too.

“I learned the truth of not your keys, not your coins,” he says, “and also that simply holding Bitcoin outperformed every other investment, because you actually had an asset at the end of the day. As long as you held it correctly.”

That lesson directly shaped the SimplVault. A harder lesson came later, sitting with people who were not his clients but had lost access to their Bitcoin entirely.

“Those conversations changed how I run the firm,” he says. “It’s why inheritance planning isn’t optional here, and why I focus on security and backups much more than the price.”

The Principles Behind SimplB

James’s leadership philosophy is built around five commitments. Keys stay in the client’s hands, because a setup that only works while he is solvent, contactable, and honest is not really a setup, it is a promise. He says the honest thing even when it costs him a sale, including telling prospective clients to buy less than planned or stick with a setup they already have. Narrow and deep beats broad and shallow, and resisting the constant pressure to add unrelated products is, in his view, most of what makes SimplB useful. Everything gets written down, since a plan that lives only in someone’s head is an intention, not a decision. And SimplB thinks in decades, not quarters.

“It all comes down to one question,” he says. “Does this still work for the client who’s still here in ten years?”

His Advice to Aspiring Leaders

James’s advice to other founders is unusually specific to the discipline it took to build SimplB.

“Pick something narrow and go deeper into it than anyone else is willing to,” he says. “The instinct in a young market is to widen out, add products, add asset classes, chase whatever’s moving. It looks like ambition and it’s usually avoidance, because depth is harder and takes longer to show anything.”

He is equally direct about the unglamorous groundwork most founders skip. “Do the boring work early. Licensing, compliance, documentation, process. Nobody claps for any of it, and it decides whether you’re still around in five years. I spent three years on structure before a single client came through the door, and I’d do it again.”

His final piece of advice cuts against typical growth instincts entirely. “Be willing to lose money to stay right. Turning away a client who isn’t suited to what you do says more about you than anything you could pay a marketer to say.”

Where SimplB Is Headed

Four priorities currently occupy James’s attention. Growing the SimplVault sits at the top, since multisig custody with built-in inheritance is the part of SimplB’s work that most directly changes outcomes for clients, and demand from family offices, companies, and trusts is accelerating.

He is also building out an adviser and fiduciary channel, since most South African advisers are not licensed for crypto assets and conversations about Bitcoin often stall as a result. James is developing referral structures, briefing notes, and estate-planning frameworks that let advisers, attorneys, and fiduciaries handle Bitcoin properly without stepping outside their own mandates.

Alongside that, he continues writing the SimplB Bitcoin Book Series, with ten additional titles scoped covering self-custody, inheritance, tax and SARS considerations, pricing, and where Bitcoin fits on a South African balance sheet. Finally, James is exploring venture capital and investor partnerships to expand SimplB’s model across the African continent.

The Leaders Column Perspective

What distinguishes James Caw is not that he believes in Bitcoin; plenty of people do. It is that he built an entire regulated company around the least exciting part of owning it: what happens when the owner is no longer around to manage it themselves. Custody and inheritance rarely make headlines, yet James has staked his entire business on the idea that they matter more than price ever will.

His own early losses read less like cautionary footnotes and more like the actual blueprint for SimplB’s multisig design. In an industry still driven largely by speculation, James has built something closer to infrastructure, narrow, deliberately unglamorous, and built to still make sense in 2035.
