Venture debt explained
What it is, how facilities are structured, what they actually cost, and the situations in which taking one is a mistake. Written for founders and finance teams approaching debt for the first time.
In brief
- Venture debt is sized against revenue and secured, in practice, on your ability to raise equity again.
- The margin is the least important number on the term sheet. Warrants, tranche conditions and covenants cost more.
- It works best drawn from strength, shortly after a round, when you do not need it.
- It works worst drawn from weakness, when it converts a funding problem into a solvency problem.
Venture debt is a loan made to a company that a bank would not lend to. That is the whole idea, and everything else about how these facilities are structured follows from it.
A conventional lender underwrites assets and cash flow. A high-growth software business has neither in any form a credit committee recognises: its assets are intangible, and it is deliberately loss-making. Venture debt exists because a specialist lender will underwrite something else instead — recurring revenue, the quality of the investors behind the company, and the reasonable expectation that the business will raise equity again before the loan matures.
What venture debt is
The category covers a range of instruments that share a structure: senior secured term debt, sized against revenue rather than assets or EBITDA, with an equity component attached, lent to companies backed by institutional investors.
How it differs from a bank loan
Four things, in order of how much they matter to a borrower:
- It is sized against revenue. A typical facility is three to five times annual recurring revenue, discounted for contract length and customer concentration. Nothing about your balance sheet enters the calculation.
- It costs several times more. Effective annual cost of 12% to 25% is normal, against low single digits for secured bank debt.
- It carries warrants. The lender takes a small equity option alongside the interest. Not dilution in any meaningful sense at the level involved, but real cost.
- It moves faster and asks harder questions. Six to ten weeks is typical, and the diligence is about your revenue and your cap table rather than your accounts.
Who provides it
In Europe, almost entirely specialist credit funds. A small number of banks run venture lending desks, generally lending against a sponsor relationship rather than the borrower, and their appetite moves with the cycle in a way the funds' does not.
How a facility is structured
Five components. Each is negotiable, and borrowers routinely negotiate only the first.
Sizing and tranching
Facilities are quoted as a multiple of annual recurring revenue, but the multiple is applied to a discounted figure rather than your headline number. Revenue on annual contracts with a single large customer is worth less to a lender than the same revenue spread across fifty customers on three-year terms.
Most facilities are now tranched. You sign for the full amount and access it in stages, with the later tranches conditional on hitting revenue milestones. Read those conditions as though you will miss the milestone, because a meaningful fraction of borrowers do.
Term, interest and amortisation
Three to five years is standard, commonly with an interest-only period of twelve to eighteen months followed by straight-line amortisation of principal. The interest-only period is worth negotiating hard: it is the portion of the facility that behaves like equity, and extending it by six months changes your cash profile far more than shaving fifty basis points off the margin.
Warrants
The lender receives an option over a small percentage of fully diluted equity, typically 0.5% to 2%, usually struck at the price of your last round. Coverage is the number to negotiate, and the strike price is the number most borrowers forget to.
Security and covenants
Expect an all-asset debenture: a fixed and floating charge over everything the company owns, including its intellectual property. In enforcement this is worth a small fraction of the facility, which is precisely why the covenants matter more than the security does.
What it actually costs
The margin quoted on a term sheet is roughly half the story. Total cost comprises the interest, the fees, and the expected value of the warrants — and the third is usually the largest single component for a company that performs.
| Component | Typical level | Cost over term |
|---|---|---|
| Interest margin over base | +750bps | £6.9m |
| Arrangement fee | 1.0% | £150k |
| Unused line fee | 0.5% | £90k |
| Warrant coverage at 3× exit | 1.0% | £1.8m |
| Prepayment protection, year 2 | 2.0% | Situational |
Two observations. The warrant line is the one that varies most and is negotiated least. And prepayment protection — the penalty for repaying early — is worth attention precisely because the good outcome, raising a large round and clearing the debt, is the one that triggers it.
When venture debt makes sense
The instrument does one thing well: it buys time at a lower price than equity, for companies whose value is rising predictably. Specific situations where it works:
- Extending runway between rounds, where the extra quarters materially improve the metrics you will raise against.
- Funding a specific, bounded investment with a modelled payback — a market entry, a plant, a sales team build.
- Financing working capital in a business whose revenue is contracted but collected slowly.
- Bridging to a known event: a signed contract, a closed acquisition, a committed equity round.
When it does not
The general principle is that debt is a claim on future cash. If you cannot describe, in a sentence, where that cash comes from and when, you are not financing growth — you are borrowing against the hope of it. The best time to raise a facility is three to six months after a round closes, when you demonstrably do not need it and your negotiating position reflects that.
How the process runs
Six to ten weeks from first conversation to funds, assuming nothing unusual. In sequence:
- Preparation — a data room, a model, and a clear answer to what your lead investor will do in a downside scenario.
- Approach — four to six lenders, run in parallel. Fewer than four and you have no leverage; more than six and you cannot service the diligence.
- Indicative terms — non-binding, typically within two weeks.
- Credit committee — the lender's internal approval. This is where deals die, and where a weak sponsor answer kills them.
- Documentation — four to six weeks with lawyers on both sides.
- Conditions precedent and drawdown.
Running a competitive process is the single highest-return thing a borrower can do, and the thing first-time borrowers most often skip. The difference between one term sheet and four is routinely worth more than every other negotiation combined.
