What is venture debt?
Venture debt is a loan for venture backed growth companies. This guide explains who uses it, how it works, what it costs and when the risks may outweigh the benefits.
In brief
- Venture debt is a loan for VC backed growth companies, usually used alongside equity rather than instead of it.
- It can reduce dilution, but the company must repay the loan even if growth or the next funding round disappoints.
- The headline facility may include later portions that are available only if the company reaches agreed milestones.
- Compare the full cost and downside rights — not just the interest rate — and borrow only for a clear purpose the company can support.

Venture debt is a loan designed for fast-growing companies that have already raised money from venture capital investors. It can give a company more time to reach its next milestone without selling as much additional equity. Unlike equity, however, the money must be repaid, interest is charged and the lender receives contractual rights if the company falls behind.
That trade-off is the heart of venture debt. It can reduce dilution — the loss of existing ownership when new shares are issued — when the business performs well, but it adds fixed obligations when performance is weaker than planned. The right question is therefore not simply whether venture debt is cheaper than equity. It is whether the company can use the extra capital to create more value while retaining enough cash and flexibility to repay it.
Why venture debt exists
A conventional lender often starts with a company’s current profits, cash generation or physical assets. Those are the most obvious sources of repayment if the business struggles. Many technology and life sciences companies look weak through that lens: they may be deliberately spending more than they earn, own few physical assets and expect growth to take several years.
A venture debt lender looks at a broader picture. It will still need a credible route to repayment, but it may place more weight on the company’s investors, recent equity funding, cash runway — how long the company can operate before it runs out of cash — growth, product progress, management team and ability to raise another equity round. The lender is taking confidence from the whole financing story rather than from current profit alone.
This does not mean any loss-making company can borrow. The stronger candidates usually have professional investors, a well-defined use for the money, evidence that the business is progressing and enough capital to survive a reasonable downside. Debt is least helpful when it is being used as a last attempt to postpone an unresolved cash crisis.
Venture debt, venture capital and ordinary business loans
| Question | Venture debt | Venture capital | Conventional business loan |
|---|---|---|---|
| What does the company receive? | A loan that must be repaid | Cash in exchange for shares | A loan that must be repaid |
| What does the provider rely on? | Growth prospects, investors, future funding and sometimes revenue or assets | The future value of the company | Usually current cash flow, profit or assets |
| Does it dilute ownership? | Usually much less than equity, although warrants can cause some dilution | Yes | Normally no |
| Are payments required? | Yes: interest, fees and repayment of the original loan amount | No scheduled repayment | Yes: interest, fees and repayment of the original loan amount |
| What happens in a downside? | The lender may restrict actions, stop further drawings or enforce its rights | Shareholders absorb the fall in value | The lender may enforce its contractual and security rights |
| Typical role | Adds capital alongside an equity strategy | Provides long-term risk capital | Funds a business with established repayment capacity |
The labels are not guarantees. Some venture debt facilities resemble bank loans; others resemble growth credit or include a return linked to the company’s value. The signed documents, not the product name, determine the actual economics and risk.
What companies use venture debt?
Venture debt is most closely associated with VC backed technology, software, fintech and life sciences companies. The underlying business model matters less than the financing position: the company is growing, has institutional equity support and has a credible milestone or repayment plan.
It may suit a company that wants to:
- extend its cash runway so it can reach a product, regulatory, revenue or profitability milestone before raising more equity;
- add a cash buffer after an equity round, rather than returning to investors immediately if the plan slips;
- fund an acquisition, equipment, inventory or another defined growth project;
- reduce the amount of equity sold in a funding round; or
- bridge a short, well-understood timing gap where the next source of capital is genuinely credible.
It is usually a poor fit when the company has no clear use for the money, has very little room for repayment, is already close to running out of cash or depends on a highly uncertain future fundraise to avoid default. Borrowing can amplify a good plan; it cannot turn an unfinanceable plan into a sustainable one.
How a venture debt facility works
The company and lender agree a maximum loan amount, the period in which it can be borrowed, the cost, the repayment schedule and the rules the company must follow. The money may arrive in full at closing or be split into portions that become available at different times.
| Term | What it means | Why it matters |
|---|---|---|
| Commitment | The maximum amount the lender agrees to make available | The whole amount may not be usable immediately or unconditionally |
| Drawdown | The act of borrowing some or all of the available money | The company may need to give notice and prove that conditions are met |
| Tranche | One portion of a larger facility | Later portions may depend on revenue, fundraising or product milestones |
| Interest-only period | A period when the company pays interest but does not yet repay the original amount borrowed | It preserves cash early but can create a sharp payment increase later |
| Amortisation | Repaying the original loan gradually over time | Monthly cash outflow rises once repayment starts |
| Maturity | The final date by which the facility must be repaid | A remaining balance may need to be paid at once or refinanced |
| Covenant | A promise or restriction in the loan agreement | Breaking one can give the lender additional rights |
| Security | Assets or rights pledged to support repayment | The lender may be able to claim or sell secured assets after a serious default |
Suppose a company agrees a £5 million facility in two portions. It borrows £3 million at closing and can borrow the remaining £2 million during the next nine months if it reaches an agreed commercial milestone. The first portion may start charging interest immediately. The second portion charges no interest until drawn, although a fee might apply while it remains available.
After an interest-only period, the company begins repaying the £3 million as well as paying interest. If it never reaches the milestone, the extra £2 million may never become available. The company should therefore build its plan around capital it can actually access, not just the number in the headline.
How venture debt is repaid
There is no single repayment model. Some loans are repaid in monthly instalments after an initial interest-only period. Some leave a larger final payment at maturity. Revolving facilities may allow the company to borrow, repay and borrow again while the line remains open. The structure should match the reason for borrowing and the company’s expected cash profile.
For an early-stage company, repayment may ultimately depend on another equity round, a sale of the company, new debt or the business generating enough cash to repay the loan. That future event is not guaranteed. Management should model what happens if it arrives late, at a lower valuation or not at all.
The lender may also require early repayment after specified events, such as a sale of the business, certain asset disposals or new financing. The company may be allowed to repay voluntarily, but an early repayment fee or a contractually required minimum return can make that more expensive than expected.
What venture debt costs
The interest rate is only one part of the cost. A founder comparing offers should identify every cash payment and any potential dilution.
- Interest is the charge on the amount borrowed. It may be fixed or be floating, i.e. move with a reference rate such as SOFR (US) or SONIA (UK). For example if interest is defined as SOFR + 7% and the SOFR rate is 3.5%, the interest rate on the loan would be 10.5% (3.5% + 7%) but could continue to move as the base rate moves.
- Fees can be charged when the facility is arranged, while money remains undrawn, when the loan ends, when terms are amended or when the company repays early.
- Legal and due diligence costs may be payable by the company, including some of the lender’s expenses.
- A warrant may give the lender the right to buy a small number of shares at an agreed price. It is one way for the lender to share in the company’s success.
A facility with a lower interest rate is not automatically cheaper. It may have higher fees, a more valuable warrant or stronger protection against early repayment. Compare the total expected cost under the company’s actual drawing and repayment plan, then repeat the exercise for a downside case.
Covenants, reporting and lender control
A covenant is a promise in the loan agreement. Some covenants require the company to do things, such as provide accounts, forecasts or evidence of insurance. Others restrict actions such as taking more debt, granting security to another lender, selling important assets, paying dividends or changing the nature of the business.
A financial covenant tests a number, such as minimum cash, revenue or recurring revenue. A company can be growing and still break a covenant if performance is below the agreed threshold. Founders do not need to become lending lawyers, but they should understand what is measured, how often it is tested and what happens if the company is close to missing it.
Reporting gives the lender early visibility. Monthly management accounts, cash forecasts and key performance indicators are common examples. The company may also have to deliver a compliance certificate: a signed statement confirming that specified loan requirements have been met. A board observer may attend meetings without having a director’s vote. Neither reporting rights nor an observer seat necessarily gives the lender day-to-day control, but they do bring the lender closer to the business.
Security and what happens if things go wrong
The majority of venture debt loans are secured. This means the company gives the lender rights over specified assets to support repayment. Depending on the deal and jurisdiction, those rights may cover bank accounts, receivables, equipment, shares in subsidiaries, intellectual property or substantially all of the company’s assets.
If the company misses a payment, breaks an important covenant or suffers another event defined as a default, the lender may gain rights that it did not previously have. These can include stopping further drawings, charging default interest, requiring immediate repayment or enforcing security. The exact sequence depends on the documents, whether the company is given time to fix the problem and the lender’s response.
In practice, an early conversation may lead to lender permission, an agreement not to act on a particular breach, or a change to the loan terms. Lawyers commonly call these a consent, waiver or amendment. That outcome is not automatic. A company has more negotiating room when it identifies pressure early, communicates honestly and presents a credible plan.
The benefits and risks
| Feature | Potential benefit | Corresponding risk |
|---|---|---|
| Less equity issued | Founders, employees and investors retain more ownership if the company succeeds | The loan still has to be repaid if the company’s value falls |
| Extra runway | More time to reach a milestone before the next equity round | Extra time is wasted if the underlying plan is not fixed |
| Interest-only period | Lower cash payments at the beginning | Repayments can rise sharply when the period ends |
| Later tranches | The company avoids paying interest before it needs the money | Capital may become unavailable when performance weakens |
| Lender discipline | Reporting and covenants can create useful early warnings | Restrictions may limit choices when the company needs flexibility |
| Warrants | Can reduce the lender’s required cash return | Create dilution and can be difficult to value at signing |
| Security | Makes lending possible where the company lacks profit | Important assets may be exposed after a serious default |
Venture debt reduces dilution only if the company can carry the debt. A loan that forces an emergency fundraise can destroy the advantage it was meant to create.
When should a company raise venture debt?
The strongest time to approach lenders is often when the company has recently raised equity, has meaningful cash and is performing to plan. That may feel early, but the company’s investors, runway and recent due diligence can make the credit story easier to assess. Waiting until cash is running out usually weakens both eligibility and negotiating leverage.
Timing should follow the use of funds. If the debt is intended to reach a product launch or revenue milestone, the company should allow for delay and preserve enough cash to service the loan. If it is intended as insurance, check how long the money can remain undrawn and what could cause the commitment to expire or be cancelled.
The board should compare venture debt with raising more equity, slowing spending or choosing a different type of credit. The decision should be based on the whole capital plan, not on avoiding dilution at any cost.
Questions founders should ask before raising venture debt
- What specific milestone or investment will the debt fund?
- How much is available at closing, and what conditions apply to later drawings?
- What is the total cash cost, including interest, fees, expenses and early repayment charges?
- What warrant or other right linked to the company’s shares is included?
- When do repayments begin, how large are they and what remains due at maturity?
- What happens to runway if revenue is below plan or the next equity round is delayed?
- Which decisions require lender consent, and which financial measures will be tested?
- What assets secure the loan, and what can the lender do after a default?
- How has the lender behaved when comparable companies missed plan?
- Can the company manage the reporting and compliance work for the full life of the facility?
Where venture debt sits within growth lending
Undiluted uses growth lending and growth debt as broad terms for debt capital provided to growth companies. Venture debt is an important part of that market, but it is not the whole category.
Venture debt most accurately describes lending to venture-backed companies, commonly while they are still investing ahead of profit. Growth credit can refer to later stage or more repayment-focused lending, while recurring revenue lending places greater weight on predictable income. Banks and non-bank debt funds can participate across these areas.
The boundaries are not fixed, and lenders use the labels differently. A founder should look beyond the name and ask what supports repayment, how the loan is structured, what it costs and what changes in a downside.
The bottom line
Venture debt is borrowed capital for VC backed growth companies. Its appeal is straightforward: the company can add funding while selling less equity. Its risk is equally straightforward: repayments and lender rights remain even when growth disappoints.
Used for a clear purpose, raised while the company has leverage and sized against a realistic downside, venture debt can be a useful complement to equity. Used to hide a structural cash problem or depend on a perfect next fundraise, it can reduce rather than extend the company’s options.
