Every one of these ten made real decisions, and choices are portable. Arnault chose to keep the name and burn the business under it. Rihanna turned down a cheque. Huang funded a decade of software out of gaming margin while his stock sat underwater. What follows is an inventory of the things sitting underneath the choices, which are not portable at all.
Start with the currency, because it eats everything else
Between 2022 and the end of 2024 the Egyptian pound went from 19.16 to the dollar to 50.83 — it lost 62% of its dollar value in under three years, most of it in two step-changes. The naira fell roughly 70% across 2023–24.
Now run an ordinary business through the March 2024 Egyptian move, when the pound went from 31 to about 50.5 overnight. Take a company with a 25% net margin: 100 of revenue, 40 of imported inputs, 35 of local cost, 25 of profit. The morning after, those inputs cost 65.2 — and the business earns nothing. To restore the old margin you must raise prices 25% in the same month your customers' real incomes fell by a third. Measured in the currency that actually buys equipment and travel, profit fell from $0.81 to $0.49 per hundred of revenue: local profit has to grow 63% just to stand still.
Which engines are structurally closed
✕Buffett — closed by the currency itself
His engine is float: other people's money held at negative cost and compounded for sixty years. Float is only free if the unit it is held in holds its value. Egyptian headline inflation averaged 28.3% in 2024. Float held in a currency losing a quarter of its purchasing power annually is not negative-cost leverage — it is a liability growing 28% a year while you try to out-invest it. Add four more institutional gifts he needed: insurance regulation permitting retained reserves, sixty years of continuous market pricing, no capital controls, and deferral of tax on unrealised gains.
✕Zell — closed, and "no cheap debt" undersells it
His real instrument was the thirty-year fixed-rate non-recourse loan: the lender carries interest-rate risk for three decades, and if the asset fails you hand back the keys and keep your house. That product exists in the United States because of government-sponsored securitisation and essentially nowhere else on earth. In Cairo in late 2024 the overnight lending rate was 27.25%. Financing a property yielding 7–8% at 22–25%, with recourse and a personal guarantee, is negative carry with an unlimited downside. The structure inverts: he had capped losses and unlimited upside; you have capped upside and unlimited losses. And the second half of his engine is missing too — without a functioning bankruptcy code, distressed assets never become orderly inventory. A failed building sits in litigation for nine years.
✕Naval — closed by a piece of paper
The smallest missing institution and the most decisive: a written letter from a securities regulator saying a thing is permitted before you build it. In most of the world regulators do not pre-clear — you discover the answer through enforcement, after you have users. This is precisely why the rational move for a Lagos or Karachi founder is a Delaware or ADGM holding company with the local operation as a subsidiary. You are importing the one institution you cannot build.
✕Arnault — the gift that looks most like skill
FF 400m of equity he did not have, three-quarters from a bank syndicate plus hundreds of millions of state money, after an introduction from a former presidential official. That kind of capital does exist in Cairo, Lagos and Jakarta. It arrives attached to a political principal who can revise the terms later.
What Sawiris actually teaches
He is the only one of the ten who built primarily where you are building, and he teaches three things. The third is the expensive one.
- Go where the incumbents will not underwrite. The Algerian, Iraqi and Bangladeshi licences were cheap because global operators could not price the risk and he could.
- Prepaid — and this is the mechanism people skip. Poor customers paying before they consumed meant the network was funded by its own users, not by capital raised in a market that had none.
- The state is a counterparty in every deal whether or not it is on your cap table. Algeria blocked the sale of Djezzy using a pre-emption right, its sovereign fund took 51%, and the arbitration claim was held inadmissible in 2017 and definitively rejected in 2020. Eight years, nothing recovered.
He was one of Egypt's most protected men, with treaty cover and world-class counsel, and the best asset was taken anyway. Treaty protection is a cost of litigation, not a put option. Build as though the state can take the crown jewel, because it can — and never let the crown jewel depend on a single relationship with it.
What remains open — and it is more than a consolation
01Earn hard, spend soft
The largest arbitrage available to a technically capable person on earth right now. Egypt's outsourcing exports went from $2.4bn in 2022 to roughly $5bn in 2025 — tens of thousands of people already run this trade. A Cairo engineer billing $40 an hour against Cairo costs operates at a margin no London shop can survive.
But treat the payment rail as a P&L line, not an admin detail. Converting $1,000 through one common processor costs about $85 all-in; through another, about $22. On $200,000 of annual billings that difference is $12,600 — a senior salary. Choose the rail with the seriousness you would choose a supplier.
02Treasury discipline, because money stops being yours to move
Egypt's 2022 letter-of-credit mandate left roughly $9.5bn of goods stuck at the ports. Pakistan blocked over $1bn of multinational dividends for ten months. Nigeria trapped more than $800m of foreign airline revenue. None of those companies did anything wrong. The rule: hold hard currency offshore in a legitimate declared structure, convert on a payroll schedule rather than on receipt, and assume anything inside the local banking system may be illiquid for twelve months.
03Make the customer your lender
The Sawiris and Bezos mechanism, and it is the same mechanism. When working capital costs 22%, sixty days of customer float on 10m of revenue is worth around 360,000 a year in avoided interest — frequently the entire net margin. Annual prepayment at a two-month discount, deposits, cohort courses, setup fees, staged payments, subscriptions.
And the inverse, which is the one that quietly kills people: a 90-day receivable priced in local currency is a short position against your own money. Cash today converts at today's rate; the invoice you write in January is worth a third less when it clears in April. Price in hard currency with local settlement at the day's rate wherever your buyer will bear it.
04Take the equity, not the fee — this one is a posture, not a passport
Rihanna's decisive act is the most copyable thing in the entire book. Every capable operator in an emerging market is periodically offered a fee by a party who wants the thing only they can do — local distribution, local compliance, local talent, local trust. That is the moment. Take the equity.
05Build what a foreign consolidator must eventually buy
The only reliable liquidity event in your environment. Amazon paid $580m for Souq; Uber paid $3.1bn for Careem; VimpelCom bought Sawiris's bundle. That imposes engineering requirements from day one: a clean cap table in a jurisdiction the acquirer's lawyers recognise, audited accounts in hard currency, and a position in licence, distribution or user base that cannot be rebuilt faster than it can be bought.
06Where there is no reliable exit, the distribution is the exit
The one Blakely and Hormozi actually ran. Both owned everything and took cash out along the way — Hormozi's roughly $42m of distributions mattered more than his sale. Compounding inside the vehicle, the Buffett–Bezos–Huang move, is a leveraged bet on your country's currency and stock market. You do not have that bet available. Take the money out, convert it, hold it outside, and let the business be a machine that produces hard currency rather than a share certificate you hope someone revalues.
Eight of these ten had a floor under them — a father's brokerage, a jeweller who took half the equity in his son's deals, an engineer's household, a physician, a trial lawyer, a Sawiris. The two who genuinely did not each needed an event nobody can buy.
And the clocks read thirteen years, twenty-three years, thirty-three years. Nothing here is a shortcut. The difference is only that some of these engines will not start where you live — and knowing which ones is worth more than another year spent trying to start them.
