Module 1 · Capital in Africa · Lesson 2

The African capital stack

The capital stack is the ordered set of funding sources a business can draw on, from the cheapest and most restrictive to the most expensive and most flexible. Knowing where a business sits in that order explains most of why a funding application succeeds or fails.

Why the order matters more than the list

Every funder occupies a position defined by two things: what they get paid, and what happens to them if the business fails. A senior lender is paid a fixed rate and stands near the front of the queue if things go wrong. An equity investor is paid only from what remains after everyone else, and stands at the very back. Everything between those poles is a negotiation about risk and reward.

That ordering explains the single most common reason a funding approach fails: the business approached a funder whose position in the stack does not match the risk it is asking them to take. A bank declining an early-stage business is not a judgment on the business. It is a lender being asked to take equity risk for lending returns, which its own funding cost makes impossible.

The layers, from the back of the queue forward

Founder and internal capital. Savings, retained earnings, and revenue reinvested. The cheapest capital in cash terms and the most expensive in personal risk. Most African businesses run on this far longer than businesses in deeper markets.

Friends, family and angels. Small amounts, priced informally, usually decided on trust rather than analysis. Angels bring a real advantage beyond money — an experienced angel who has built and sold a business is often the first person to tell a founder something uncomfortable and correct.

Venture capital. Institutional equity for unproven models with large potential markets. Concentrated in a small number of sectors and a small number of cities across the continent.

Growth equity. Institutional equity for proven models that need scale, usually minority stakes. Covered in what is growth capital.

Private credit and mezzanine. Debt priced for higher risk than a bank will accept, sometimes with an equity component attached. Fills the gap between what a bank will lend and what an equity investor will fund.

Bank and asset-backed lending. The cheapest external money, and the most conditional. Requires security, a trading history, and serviceable cash flow.

Trade and working capital instruments. Facilities tied to a specific transaction rather than the business as a whole — a confirmed order, an invoice, an import. Because the funder is underwriting the transaction, businesses that fail a general credit assessment can sometimes still access these.

Development finance and grants. Capital with a mandate attached — job creation, climate, women-led enterprise, regional development. Cheaper than the commercial equivalent, slower to access, and carrying reporting obligations that persist for years.

Where the African stack has gaps

A capital stack is only useful if every layer is populated. Across most Sub-Saharan markets, several are thin.

The most persistently discussed gap sits between what angels can write and what institutional venture funds will consider — large enough that a business can be too big for informal capital and too small for a fund, simultaneously. A second gap sits between venture and growth equity, where a company that has proven its model is still below the minimum cheque size most growth funds will deploy.

There is also a structural gap in private credit. In markets with deep debt capital, a profitable business needing expansion capital borrows it. Where private credit is thin, that same business is pushed toward selling equity it did not need to sell — which is one reason dilution levels in African growth businesses are often higher than the underlying risk warrants.

How businesses actually assemble funding here

Because layers are missing, funding in African markets is more often assembled than selected. A single expansion might combine a development finance facility, a commercial bank overdraft secured on debtors, an equity investment, and a grant covering a specific component such as training or energy efficiency.

This is what blended finance describes: combining capital with different return expectations in one structure, so that concessional or mandate-driven money makes a transaction possible that purely commercial capital would not fund alone. It is more work to arrange and it introduces multiple sets of conditions that must be reconciled — but in markets with gaps in the stack, it is frequently the only route that closes.

What ranking means when things go wrong

The queue is not theoretical. If a business fails, the order of repayment is enforced, and it determines who recovers anything at all. Secured lenders realise their security first. Unsecured creditors — suppliers, landlords, and often the tax authority in a defined position — follow. Shareholders rank last, which in most failures means they recover nothing.

This is why funders care so much about instruments that look like technicalities to a founder. A personal surety moves the lender's claim beyond the company and onto the owner's own assets. A cession of debtors gives a funder first call on money owed to the business. A negative pledge stops the business granting security to anyone else later, protecting the funder's position from being diluted by a subsequent lender.

Understanding this changes how a founder reads a term sheet. Terms that appear to be about control are usually about queue position — and they are negotiable in ways that headline pricing often is not.

Reading your own position in the stack

The practical use of the stack is diagnostic. A business with three years of audited financials, security to offer and predictable cash flow sits in bank territory and should not be giving away equity. A business with a confirmed order it cannot fund sits in trade finance territory. A business whose model is unproven sits in venture or angel territory regardless of how large the opportunity looks.

Most unsuccessful funding processes we see are not weak businesses. They are businesses in the wrong queue. Investor types and terms defines each participant precisely.

Questions, answered

What does capital stack mean?

The ordered set of funding sources available to a business, arranged by what each funder is paid and where they stand in the queue if the business fails. Senior lenders sit at the front with fixed returns; equity investors sit at the back with unlimited upside.

Why do banks decline early-stage businesses?

Because a lender earns a fixed interest rate whether the business grows tenfold or merely survives. That return cannot compensate for the risk of an unproven model. It is a structural mismatch, not a judgment on the business.

What is the missing middle in African funding?

The gap between what informal and angel capital can provide and the minimum cheque size institutional funds will deploy. Businesses in that range can be simultaneously too large for one source and too small for the next.

What is blended finance?

Combining capital with different return expectations — commercial, concessional and grant — in a single structure, so that a transaction becomes fundable that purely commercial capital would not support alone.

Is equity or debt better for an African growth business?

It depends entirely on position in the stack. A profitable business with security and predictable cash flow should generally borrow rather than dilute. An unproven model cannot service debt and needs equity. The instrument should match the risk, not the preference.

Why is dilution often higher in African markets?

Because private credit is thin. In deeper markets a profitable business needing expansion capital borrows it; where that layer is underdeveloped, the same business is pushed toward selling equity it did not structurally need to sell.
