When should a growth company use debt?

A growth company should use debt when it has a clear, valuable use for the money and a credible way to repay it—even if growth or fundraising takes longer than planned. Debt is most useful as an accelerator for a sound plan, not as a rescue for a company that has run out of financing options.

Venture debt and growth credit can preserve more ownership than an equity raise, but the company exchanges dilution for fixed obligations. Interest, fees and principal do not disappear when revenue misses plan. The decision should begin with repayment and downside resilience, not the advertised facility size.

Five tests before taking growth debt

The best time is often when the company does not urgently need it

For a venture-backed company, the strongest time to raise venture debt is often alongside or shortly after an equity round. The balance sheet is liquid, investors have recently completed diligence and the company has time to run a competitive process.

Borrowing from strength can improve choice. Management can compare providers, negotiate covenants and walk away from unsuitable terms. It can also arrange an undrawn tranche or facility before a downturn makes new credit difficult.

That does not mean every company should add debt after an equity round. Unused facilities can carry fees, availability can expire and later drawings may have conditions. Borrow only when the facility serves a defined capital plan.

Waiting until cash is low creates the opposite dynamic. A lender sees shorter runway and fewer alternatives. The company may accept expensive or restrictive terms, while the debt itself does not solve the need for permanent capital.

When debt can make strategic sense

To reach a defined milestone

Debt can bridge the period to a product launch, regulatory result, revenue target or profitability milestone. The milestone should be achievable within the available cash and should improve the company’s financing or repayment capacity.

The relevant question is not only “What happens if we succeed?” Ask what happens if the milestone arrives six months late or produces a weaker result. If the debt becomes unmanageable in that case, equity may be safer.

To extend runway after equity

Runway is the period before cash is expected to run out. A modest facility can give a company more time to execute after an equity raise without selling the same amount of additional ownership.

Model net runway, not headline runway. Interest and principal pull cash back out of the business. A £5 million loan does not create £5 million of lasting liquidity once fees and repayments are included.

To fund repeatable commercial growth

Debt can support sales hiring, customer acquisition or market expansion when the company already understands the economics. Retention, gross margin and the time needed to recover acquisition spending should be supported by evidence.

Equity is usually better for testing whether a market exists. Debt is better suited to scaling a model that has already shown repeatability and can generate cash or a valuable financing milestone before the loan matures.

To finance working capital

Working capital is the cash tied up in day-to-day trading. Fast growth can create a gap when suppliers and staff must be paid before customers settle invoices. Debt can finance that timing difference, particularly when contracts and collections are visible.

A revolving, invoice or asset-based facility may fit better than a general term loan. Match the product to the cash cycle so the company can repay as customers pay.

To buy equipment or build capacity

Equipment, laboratories, manufacturing capacity and other long-lived assets can be sensible debt uses because the benefit extends over time. Asset finance may match payments to the asset’s useful life and preserve unrestricted cash.

Specialist assets may have little resale value. The decision should rely on the cash or strategic benefit of the investment as well as the lender’s collateral value.

To make an acquisition

Debt can finance part of an acquisition and reduce the equity needed. The strongest cases have a strategic fit, disciplined price, a realistic integration plan and combined cash flows that support the enlarged debt.

Do not count every hoped-for saving as repayment capacity. Include fees, integration costs, customer loss and delay. If the acquisition must perform perfectly to service the loan, the structure is too fragile.

The repayment question

Every loan needs a primary source of repayment. For a profitable growth company, this may be operating cash flow. For a venture-backed company, repayment may involve future cash generation, refinancing, an exit or additional equity. The more the plan depends on a future event, the more carefully the company should test its certainty and timing.

A future equity round can be part of the plan, but uncommitted investor support is not cash. Investors may change strategy, require a lower valuation or decline to fund a company that has too much debt. New investors may also dislike seeing part of their round used to repay an earlier lender.

Cash already on the balance sheet provides time and protection, but unrestricted cash intended to fund losses is steadily disappearing. It should not be counted twice as both operating runway and debt repayment.

A credible repayment plan should identify:

• the expected source and date of repayment;
• the evidence supporting that source;
• what management controls before the repayment date;
• what happens if the source is delayed or smaller; and
• the actions available before cash becomes critical.

Build a downside case before negotiating

A base forecast shows management’s expected plan. A downside case shows how the company responds when important assumptions are worse. For growth debt, the downside model should be monthly and extend through final maturity.

At minimum, test slower revenue, weaker gross margin, higher costs, delayed collections, an unavailable tranche and a next equity round six or twelve months late. Include interest, fees and principal on the dates they are actually payable.

Then identify the lowest cash point, covenant headroom and the last date on which management can act without lender consent. Covenant headroom is the gap between forecast performance and the level required by the loan.

Cost reductions are not instantaneous. Redundancy costs, notice periods, contract commitments and customer effects can delay savings. A downside plan that assumes costs vanish in the same month as revenue falls is not conservative.

How much debt is sensible?

The maximum offered by a lender is not the amount a company should borrow. Size debt from the use, repayment capacity and downside cash need.

A practical approach is to calculate three amounts:

1. 1the capital required to complete the defined plan;
2. 2the amount the company can service through the loan term in a realistic downside; and
3. 3the amount that does not make the next equity round or strategic exit unattractive.

The sensible facility is constrained by the lowest of the three. A larger headline facility can still be useful if drawings are optional, available long enough and not subject to conditions that fail in the downside case.

Structure can matter more than size

A well-matched facility releases cash when it is needed and asks for repayment after the financed investment has produced value. Compare:

• committed cash at signing versus conditional later tranches;
• the availability period and any extension options;
• cash interest, payment-in-kind interest and fees;
• the interest-only period and principal repayment schedule;
• minimum cash, revenue or other financial covenants;
• security, account control and restrictions on new borrowing;
• warrants or other rights linked to future shares; and
• early repayment charges and what happens on a sale or equity round.

Payment-in-kind interest is added to the balance instead of paid immediately. It protects current cash but increases the amount owed. A tranche is a portion of the facility made available separately. Neither feature is automatically good or bad; both must fit the company’s forecast.

When not to borrow

• The company has no specific use beyond postponing an equity raise.
• The business model, product or market is still too uncertain to support fixed obligations.
• There is no credible repayment source other than an uncommitted future round.
• Current cash is low and debt is being considered as a last resort.
• A small miss would cause a covenant breach or leave too little cash to operate.
• The investment takes longer to produce value than the facility remains available or outstanding.
• The company needs more capital than it can responsibly repay.
• The loan would make the next financing, sale or strategic partnership materially harder.
• Management cannot produce timely accounts, cash forecasts and lender reporting.

Equity is expensive in ownership terms, but that alone is not a reason to borrow. Equity absorbs uncertainty. Debt concentrates it into payment dates, covenants and maturity.

A founder and CFO decision process

1. 1Write a one-page use-of-proceeds plan with amount, timing and measurable outcomes.
2. 2Build monthly base and downside cash models through maturity.
3. 3Identify primary and backup repayment sources without counting the same cash twice.
4. 4Compare debt, equity and a blended structure using the actual terms.
5. 5Test how the facility affects the next equity round, an exit and additional borrowing.
6. 6Ask the board and major investors what support is genuinely available, then distinguish intention from commitment.
7. 7Negotiate size, tranches, repayment and covenants around the downside case.
8. 8Check the lender’s record in amendments and difficult situations, not only its speed before closing.
9. 9Take legal, tax and financial advice on the complete documents before signing.

The bottom line

A growth company should use debt when the capital has a defined job, the investment produces value within the financing period and repayment remains credible if the plan is delayed.

The best time to raise is often from strength: after fresh equity, before cash is tight and while the company can choose between providers. The worst time is when debt is expected to replace missing permanent capital.

Debt should improve the company’s options. If the proposed loan removes the ability to survive a normal growth miss, it is likely too large, too early or structured in the wrong way.
