Builders versus Owners

Every evening one of Africa's most valuable exports taxis down a runway and appears on no customs manifest: a founder with a laptop, a cap table and an unfinished idea. The argument we keep having is about who is leaving. The one that decides the next decade is who ends up owning what they build. This brief tries to measure it, and to be honest about where the measurement runs out.

The question this brief answers

When African talent leaves and its companies are owned abroad, is the real loss the people, or the ownership of what they build?

Argument in briefFor thirty years the debate has counted departures and called the loss brain drain. It reads the wrong column. The value a company creates at home, its wages, procurement and taxes, mostly stays; the ownership of it does not. Read through primary-income outflows, the destination of control at exit and the ownership split on three real companies, the ownership account runs opposite to the funding totals that reassure us. The lever is the register, not the border: who holds the equity when the value lands. Circulation works for tradeable, capital-light sectors, and fails for the clinician, a one-way loss no policy recovers.

These are the four figures usually offered as evidence that ownership is coming home. Three measure something real; none measures ownership retention. Holding that distinction is the task of this brief.

01 · The two accounts

We count the builders at the gate. We rarely audit the owners.

For thirty years African policy has had one word for the executive who moves to Amsterdam: drain. A vivid word doing far too much work.

A drain runs one way; the evidence looks more like a tide. AnnaLee Saxenian documented the return leg across Taiwan, India, Israel and China, where engineers who supposedly drained into Silicon Valley came back to seed the industries their leaving was meant to kill.7 She called it brain circulation, real for some sectors and false for others.

The harder paper is the one most cited and least read right. Studying Indian patent citations, Agrawal, Kapur, McHale and Oettl find skilled emigration harms domestic knowledge access on average, while the diaspora's access matters most for a country's highest-impact inventions.8 The channel is an offset, not a reversal, which the "brain bank" slogan flattens into a reassurance its authors never offered.

Africa is now running that experiment at continental scale, almost by accident. Founders leave Lagos, Nairobi and Johannesburg in numbers you can count; nearly every serious African start-up is incorporated in Delaware before its founder books a flight;9 and the diaspora wired roughly $95 bn home in a year, more than most categories of foreign direct investment.13 The flows are enormous, run both ways, and no institution manages either.

The migration argument is really an ownership argument wearing a passport. A builder makes value early, visibly, often locally; an owner captures it late, wherever the paperwork points. So every economy keeps two sets of books, one for who makes the value and one for who keeps it. The continent has read the first to the decimal and barely opened the second; what follows tries to open it, one measurable line at a time.

Brain drain is a balance sheet read down a single column.

Diagelo · The Ownership Question
The Diagelo framework

The Ownership Wedge

The value a company keeps at home and the ownership it keeps at home start together and part ways across the life of the capital. The space between them is what this brief measures.

100% 50% 0% Share retained at home Operating value, home Ownership, home the wedge built at home, owned abroad MTNMTN 62% SaSafaricom 60% JJumia 8% built here, owned elsewhere Founded Seed Series A Series B Exit / listing Gold points are the three measured companies from Section 3, placed on the ownership line at their real position.
How to read it. The upper line is the share of a company's annual value, its wages, procurement and taxes, that stays in its home market; the lower line is the share still owned at home. Both trace the typical path from founding to exit, a model, not a measurement. The shaded space between them is the wedge: value built in one place, owned in another. The three gold points are the real companies from Section 3. Safaricom and MTN sit above the default because they listed at home; Jumia sits near the floor because it did not. Where a company lands is set at the exit, and it is a choice.
Diagelo framework. The two curves illustrate the mechanism and carry no measured values; the ownership path is the default drift when nothing keeps local investors on the register. The three marked points use the operating-value and ownership estimates for Safaricom, MTN and Jumia from Section 3. It gives the two-column argument a single shape. Framework, not a measurement
02 · What ownership looks like, and what it hides

Does the proxy everyone uses actually measure ownership?

The case that ownership is coming home rests on one number: since 2019, Africa-based investors have led 59% of million-dollar-plus deals for Big Four start-ups, against 37% elsewhere.3 The number is real, and the wrong instrument for the claim.

Lead-investor nationality tells you who runs the round, not who owns the company. The most active "African" investors this cycle are, to a striking degree, foreign development-finance institutions, Britain's BII, the World Bank's IFC, France's Proparco, the Netherlands' FMO, Germany's DEG and America's DFC, and every African Series A in early 2026 carried at least one.16 A Nairobi manager deploying European limited-partner money is placing offshore capital, not holding domestic ownership, and counting him as the latter is the quiet substitution the optimistic reading depends on.

The "domestic investor" bucket compounds this, folding in African corporates whose treasuries write cheques on strategic, not patient-venture, mandates, mixing genuine local risk capital, recycled development finance and balance-sheet plays that behave nothing alike.16 None of this makes the 59% false; it makes it carry far less than asked, and the honest response is to look for measures that speak to ownership directly.

The gap we could not close

The clean test would be the limited-partner composition of the largest Africa-domiciled funds: if a fund's capital is 80% Western development finance and pension money, the "African" label describes its office, not its owners. We attempted that for the ten largest and could not finish it: fund-by-fund LP composition is not publicly disclosed, and what is public shows only that pan-African funds raise heavily from the same DFI cluster.16

So we will not report a number we cannot source. The limitation is itself a finding: the statistic doing the most work rests on a capital base whose nationality we cannot audit. An honest gap beats a confident proxy.

Two measurements speak to ownership without a proxy. The first is macroeconomic. When foreigners own domestic assets, the income those assets throw off leaves the country as investment income on the balance of payments, in the primary-income account; a persistent, widening primary-income deficit is the national accounts confessing that more of what the economy produces accrues to owners abroad.12 It is blunt, but it is the closest thing to a hard ownership-flow number the statistics produce.

Figure 01

Where does the income go when the assets are owned abroad?

How to read it. Each bar is a country's net primary-income balance for 2024: income residents earn abroad minus the larger sums paid to foreign owners of domestic assets. All three are negative; South Africa's is largest, driven by dividends to foreign holders of Johannesburg-listed equity. Egypt is hatched because no comparable 2024 figure was available.

The second measurement is transactional. At a company's largest liquidity event, the acquisition or listing, public records show where control goes.

Figure 02

Acquisition or listing, ranked by disclosed value. Acquirer domicile is public record; the split of proceeds between founders, local angels and foreign funds mostly is not.

How to read it. Nine of the ten largest exits handed control to a foreign acquirer or listing; the exception is Fawry, which listed on the Egyptian Exchange and kept ownership home. The biggest liquidity events are trade sales to US, European and Gulf strategics, and the one reliable route to domestic ownership, a home-exchange listing, occurred exactly once at this scale.

Both measurements point the opposite way from the proxy. At the macro level a growing share of what these economies produce is paid to owners abroad; at the deal level, control of the best companies relocates at the exit. Neither is fatal to circulation: the jobs and taxes are a separate account that reads far better. But this is the ownership account, and it has been left unread.

One more exhibit the title implies and honest reporting cannot yet deliver: a hand-built sample of fifteen to twenty disclosed Series B cap tables, tracing how founder and local equity dilutes as Delaware incorporation and foreign leads take the stock. It does not exist in public form anywhere on the continent, because private African cap tables are not disclosed.

The mechanics, not a measurement. Each round issues new shares to mostly foreign investors and dilutes everyone on the register; a Delaware parent and foreign leads concentrate the stock offshore.

How to read it. This is a diagram, not a chart: the proportions illustrate a mechanism and carry no measured values. Absent a deliberate effort to keep local investors on the register, each round pushes the ownership boundary down, and by Series B the domestic share of a company built at home can be a minority of its own cap table. That number no one has published.

03 · The Anchor Dividend, rebuilt

Operating value stays home almost regardless of structure. Ownership does not.

The earlier version of this instrument produced a single figure, 57¢ of every dollar of value staying home, from no model. This rebuild replaces it with three companies that actually file their numbers, and it separates two things the 57¢ silently fused: where the operating value lands, and who owns the company.

Read "home" here as the African market or markets a company operates in, and "abroad" as everything else. For each of three publicly reporting firms we can put a defensible figure on two questions. The first is where the annual value a company distributes, to staff as wages, suppliers as procurement, governments as tax, shareholders as dividends, actually comes to rest. The second is who holds the equity, and so the claim on every future dollar. The instrument below carries both, because the gap between them is the argument of this brief in two bars.

Two books for one company

Pick a company or move the slider between the three anchors, and watch the operating bar barely move while the ownership bar collapses.

Operating value that stays home
89%
Wages, local procurement and in-market tax, net of value paid offshore.
Ownership held at home
60%
Share of the equity, and of every future dollar, held on the continent.

Safaricom distributes the overwhelming majority of its value inside Kenya, where the tax and licence payments alone dwarf the dividend, yet roughly two-fifths of that dividend flows to the Vodacom and Vodafone group, and about 40% of the equity is held abroad. Operating value: mostly home. Ownership: split.

What is measured, and how. The operating figure comes from each company's disclosed value distribution: for Safaricom, the FY2020 split of KSh 111 bn in taxes and licence fees, KSh 17 bn in payroll, KSh 36 bn in supplier capital and KSh 56 bn in dividends;19 for MTN, the 2024 total tax contribution of R52.7 bn, 97% of it in African markets;20 for Jumia, an estimate, since a loss-making German group pays no dividend and discloses no payroll by country.21 The ownership figure is an author's estimate from major-holder disclosures: Safaricom ~60% domestic (Kenyan state 35% plus a mostly local free float, against ~40% held by Vodacom/Vodafone); MTN majority South African and African institutional; Jumia overwhelmingly foreign, a Berlin company listed only in New York.

The instrument makes a point the original got half-right and stated backwards. Its predecessor called incorporation a red herring and operation the lever, and for the operating account that broadly holds: a Delaware or Berlin parent barely moves where wages, procurement and tax land, because those follow the work, and the work stays. The ownership account tells the opposite story, and it is the one the title is about. Safaricom and MTN keep most of their ownership at home because they list at home; Jumia keeps almost none, a German company listed in New York, and no amount of African operating spend changes who holds the upside. Incorporation is a red herring for jobs and taxes and decisive for ownership, and conflating the two is how a real insight about operations got mistaken for a reassurance about ownership.

The gate was never the lever. Neither, it turns out, was the payroll. The lever is the register: who is on it when the value finally lands.

The Anchor Dividend, rebuilt
04 · The debt, split

Debt at 41% of capital has two readings. The original brief printed one.

"Debt finances companies built to operate, not flip" is a good line and exactly half the meaning. The other half: debt is what founders raise when equity dries up, and a rising debt share in a market with almost no exits can signal a stalled equity engine as easily as a maturing one.

Reading one · maturity

Lenders want audited books, predictable revenue and credible governance. A company that can service debt is a company with real cash flows, so a rising debt share is the sound of an ecosystem growing up, and the eligibility bar for debt does sit higher than for equity.1

Reading two · substitution

Equity into African tech fell from roughly $5 bn in 2022 to about $2.3 bn across the three years since.11 When priced equity becomes scarce and down-rounds become punishing, debt is not a maturity choice so much as the only door left open, and a debt share that climbs while equity contracts can be a distress signal wearing a maturity costume.

To adjudicate, look at who is lending, on what terms, and in what form, and the evidence tilts hard. Development-finance institutions, chief among them Britain's British International Investment, the World Bank's IFC and France's Proparco, have topped debt capital to African tech for two years running, each closing three or more deals a year while commercial venture lenders stayed thin.16 Most of that debt is dollar-denominated while borrowers earn in naira, cedi and shilling, a mismatch that turned brutal when the naira lost more than half its purchasing power between January 2023 and January 2024 and the shilling shed 22%.16 Local-currency facilities are the sensible structure and remain the exception.

Form matters as much as currency. Much of what 2025's headlines filed under record rounds was, on inspection, project finance and asset-backed securitisation rather than venture debt: Sun King's $156 m receivables securitisation put commercial banks in the senior tranche and development institutions in the riskier mezzanine; SolarAfrica's $98 m was project finance against a solar installation; Wave's $137 m carried concessional development-finance participation behind a commercial lead.17 There the commercial money takes minimal exposure and the development institutions absorb the downside, which is intelligent engineering and is not private venture capital returning to Africa. Concessional development debt and commercial venture debt point in opposite directions, and the headline 41% fuses them into one number that reads cleanly neither way.

Figure 03

Debt's rise is real; its composition changes what the rise means

How to read it. The columns are the dollar value of debt raised; the amber percentage beneath each is debt's share of all capital deployed that year (2021's share is not separately reported). Both level and share have risen sharply, which the maturity reading takes as its case. What the chart cannot show, and the caption must, is that the dominant lenders are development-finance institutions, the money is mostly dollar-denominated against local-currency revenue, and a large slice is project finance rather than venture debt, so the same bars support the substitution reading just as well.

05 · Where the thesis breaks

Where does the circulation story break down?

A brief arguing for circulation owes the case where it fails, and the clearest is the departure lounge of nurses, anaesthetists and general practitioners. Here the offset the earlier sections leaned on vanishes.

The World Health Organization sets a minimum density of 4.45 doctors, nurses and midwives per 1,000 below which basic care suffers, and counts 83 countries beneath it, most of them African; as of 2022 only Seychelles, Namibia, Mauritius and South Africa cleared it.22 Roughly one in five African-born physicians now works in a high-income country, the OECD records emigration rates above 70% for Liberia, and in 2023 nearly half of new UK doctors had trained abroad.23 The African Development Bank puts the annual cost of health-sector emigration at around $2 bn.10 A poor system that trains a doctor who then registers in Manchester has made a direct capital transfer to a rich one, and leaves nothing on any register to reactivate.

WHO / academic analysis, 2026; OECD and World Bank; African Development Bank. Data as of 2022–2024.

Every mechanism that makes founder migration recoverable is absent for the clinician. The departures are largely permanent, not the commuting Saxenian saw; a remittance buys groceries and school fees but does not staff an intensive-care unit; there is no equity to keep a departed nurse tied to the ward she left; and the loss falls on the very public systems this brief shows are hollowing out. Circulation works for sectors that are tradeable, capital-light and network-dependent, and fails for licensed, place-bound, public-service work, where the output is a person at a bedside.

Why Taiwan, India and Israel circulated, and whether the preconditions travel

The success stories are invoked so often that their preconditions have been sanded off. Taiwan's ran through Hsinchu Science Park, more than half of whose firms were founded by Silicon Valley returnees, and through a deliberate state effort to pull them back.25 Israel's ran through the state-created Yozma programme of the early 1990s, a venture-capital industry built from scratch and fed by US returnees, a Russian immigration wave, and a defence establishment that worked as a national engineering network.25 India's ran on a domestic market and IT-services base big enough to give returnees something to return to. Each case combined a strategically connected home industry, a deliberate programme to pull talent back, and a proven exit.

Set that against Lesotho, whose main human export is labour to South African mines and hospitals and which has no returnee programme nor a capital market to return capital to; or a South Africa that has the market and the exchange but built no Yozma and watches its clinicians leave for good. And even the best case carries an awkward line the literature skips: Israel kept listing its companies on foreign exchanges, so most of the financial gains flowed to overseas investors.25 Circulation brought the industry home; ownership of it largely stayed abroad, the same two-column split this brief keeps finding.

06 · The view from the highveld

A South African interlude, written from under the jacarandas.

In Pretoria you can date a memory by the jacarandas. They bloom in October, the streets go purple, and every year somebody at the braai says it: did you hear, so-and-so's daughter is in Amsterdam now. The doctor cousin is in Perth. The fintech guy from varsity is in London, doing well, and nobody is quite sure how to feel about it.

The numbers say the braai is not just anecdote. More than a million South Africans now live abroad,5 and Afrobarometer finds 27% have considered emigrating, rising to 38% among the most educated and 42% among the wealthiest.6 In early 2026 national unemployment was 32.7%, youth unemployment among 15-to-24-year-olds 60.9%, and roughly 8.1 million people were out of work.14 The people most courted by Amsterdam and London are, disproportionately, the ones who might have built the firms to employ the 60.9%. South Africa is not short of people who need jobs. It is short of owners of the things that make them.

And yet the corridor complicates the grievance. It keeps furnishing evidence for circulation: Mark Shuttleworth sold Thawte, left, then funded South African ventures from abroad for two decades, while Naspers, a Cape Town media house, built one of the world's most valuable internet holdings and chose Amsterdam for the Prosus listing.7 The current data is just as stubborn. In 2025 South African start-ups raised about $600 m, up 51%, more than 90% of it equity, the largest equity share on the continent, and took first place in equity funding since 2017.11 Departure and dynamism sit in the same dataset.

The lived truth is messier than either camp admits. The operator lost to Amsterdam on Monday is often, three years later, the angel cheque, the warm introduction to a Dutch pension fund, the first international customer. The loss is immediate and legible, the return delayed and diffuse; whoever manages only what is legible will misprice both. But the jacaranda street knows what the spreadsheet resists: the doctor cousin in Perth is not coming back, and that is a different loss from the fintech founder's.

07 · The unmanaged programme

Remittances are the largest unmanaged investment programme in Africa. Twice, someone tried to manage a slice.

Strip the $35 bn Ras El Hekma megaproject, funded by Abu Dhabi's ADQ, from 2024's headline $97 bn in African foreign direct investment, and the broad-based figure falls to about $62 bn, below the roughly $95 bn the diaspora wired home that year.1318 The diaspora out-invested the world. It just files it under groceries.

The flow deserves the comparison because it behaves better than the capital the continent chases. Over the past decade, remittances to low- and middle-income countries rose 57% while foreign direct investment to them fell 41%; the money is stable, counter-cyclical and loyal, arriving when portfolio capital flees.13 Remittances behave better than the capital we chase, yet almost every recipient country leaves a flow of that size unstructured. The instrument built to structure a slice is the diaspora bond, whose African record is a short lesson in what the idea needs.

Ethiopia is the cautionary case, twice over. It issued a diaspora bond in 2008 for the state electricity utility and again in 2011 for the Grand Ethiopian Renaissance Dam, and both fell short, undermined by distrust of the government and a default risk no patriotic premium could offset.24 The 2011 offering was not registered with the US Securities and Exchange Commission, and in 2016 the utility settled SEC charges of selling unregistered securities to US residents of Ethiopian descent, unwinding roughly $5.8 m raised from more than 3,100 investors: a bond that ended as a rescission notice.24

Nigeria is the apparent success that underperforms differently. Its 2017 issue of $300 m in 5.625% diaspora bonds due 2022 was oversubscribed by about 130%, and it worked because Nigeria did the legal work Ethiopia skipped: SEC and UK registration, a London listing.24 But $300 m raised once, against a remittance flow of roughly $20 bn a year,4 is a rounding error dressed as a milestone, never repeated or scaled. Issuance is the easy part; the binding constraints are trust and structure.

What a bond would need follows from those failures. It must be registered where the diaspora lives, both to sell and to avoid the enforcement that ended Ethiopia's; it must ring-fence proceeds and report against them, because migrants forgive a low coupon but not mismanagement; it must price the patriotic discount honestly, since an under-market bond simply fails to sell; and it must offer a local-currency option to neutralise the exchange risk that deters a dollar-and-pound diaspora from lending in naira or birr. The places that made diaspora finance work, Israel across seven decades and India at the scale of billions, had the trust and dense ties first, and no prospectus can manufacture that.

08 · The takeaway

Stop counting departures. Start auditing ownership.

The whole argument, in five moves

Where does the value go, and who ends up owning it?

One frame for the whole brief: value is built at home, ownership drifts abroad, and the space between them is the wedge. Press play, or step through it.

1 / 5

How to read it. Each move adds one finding: the departure, the split of operating value from ownership, the widening wedge, the exits that kept ownership home, and the clinician whose loss never returns. The blocks illustrate the mechanism; only the exit panel and the wedge carry the Section 3 estimates.
Diagelo synthesis of Sections 1 to 8. The isometric blocks are illustrative; the exit panel shows the Section 3 ownership-kept estimates for Safaricom, MTN and Jumia. Motion is decorative and pauses when the figure leaves the screen or when reduced motion is set. Press play, or step through

The model worth keeping is the wedge. Every economy builds value and lets some of the ownership settle elsewhere; the gap runs wider than the funding totals suggest. The talent debate, the brain-drain panic and the guilt at the gate all argue about who builds. The number that decides the next decade is who owns, and it points the other way from the reassurance those totals usually give.

Once the two accounts are separate, the policy noise quiets. Exit taxes, loyalty campaigns and visa walls all try to pin the builder in place and fail, because a builder forced to stay is not an owner you kept but a talent you wasted. The lever for the owners' account is the register, not the border. It works for tradeable, capital-light sectors and not for the clinician, whose loss no cap table can recover. And it moves ownership abroad by default, through Delaware parents and foreign listings and foreign leads, so keeping a share at home is not automatic; a board, an exchange and a policymaker have to build it on purpose.

Boards & CEOs
Run an alumni engine, not a salary auction

Structured offboarding, equity that keeps leavers aligned, a channel to send back deals, talent and customers. Retention won by force is not ownership kept.

Investors & DFIs
Underwrite the corridor, and name your own money

Price credible dual-market presence as an asset, and publish limited-partner composition: a sector that cannot audit whose capital it deploys cannot claim ownership is coming home.

Policymakers
Fix the return leg and build the exchange

Registered, ring-fenced diaspora vehicles; credential recognition; dual-listing pathways. The one reliable route to domestic ownership in the exit data was a home listing.

Founders
Leave infrastructure, keep a seat

A local managing director, local payroll, a home-market board seat. The corridor rewards founders who keep one foot anchored and punishes those who vanish.

So the questions change. A board stops asking how to keep people from leaving and asks how to stay on their cap table after they go. An investor underwrites the corridor, not the company. A policymaker stops taxing the runway and builds the exchange that lets ownership rest at home. None of this asks anyone to stay; it asks someone to own, and admits that for the doctor cousin in Perth none of it will be enough. Her loss sits on a balance sheet no register can reopen. A country does not grow rich by keeping its builders at home. It grows rich by owning a share of what they build, wherever they build it, and by being honest about the exports, clinical labour above all, from which it will collect no share. Look again at the wedge: it widens by default and narrows only on purpose. Talent does not owe geography its loyalty; geography has to earn it back, with interest.

Notes on the data

Funding trackers differ in scope, in deal-size thresholds, debt coverage and grant inclusion, which is why Africa: The Big Deal,2 Briter and Partech report different totals for the same year; each is cited and labelled. Every figure carries its source and the period it describes, and no source postdates this brief's May 2026 dateline. Where a number is analytically important but not publicly available, such as limited-partner composition, private cap tables, or a per-lender split of the debt total, that is stated in the body rather than estimated silently. The Anchor Dividend measures the value distribution and ownership of three real, publicly reporting companies rather than modelling a hypothetical firm; its ownership figures are author's estimates from disclosed major-holder data and are flagged as such.
