Venture Capital Debt: An Investor's Guide to the Risks

Brian Nichols is the co-founder of Angel Squad, an angel investing community where aspiring and active angels learn from Hustle Fund’s approach, review curated deal flow, and connect with peers.

A startup announces a loan that gives it more time to grow without another equity round. As an angel investor, you need to understand what that cash buys and what the company now owes. Repayment timing, access to the money, and lender rights can change the risk of your existing or next check.

What venture capital debt means

Venture capital debt, usually called venture debt, is a loan designed for venture-backed startups. Banks and specialist non-bank lenders provide it to supplement the equity a company raises. The company owes principal, the amount borrowed, plus the interest and fees in its agreement.

Venture capital itself is usually equity financing. An investor receives an ownership interest and accepts the possibility of losing the investment. Venture debt creates repayment obligations that remain even when growth disappoints.

The distinction matters because startups can qualify for venture debt while losing money. A lender may rely on investor backing, cash runway (the time until the company needs more money), business progress, and the ability to raise more equity rather than current profits alone. Some pre-revenue companies can qualify; requirements differ by lender and stage.

A convertible note is different. It starts as debt and is generally designed to become equity when a specified event occurs. Venture debt is generally designed to be repaid, although particular agreements can include conversion features. Our guide to debt and equity capital explains the broader financing choices.

How venture debt works

The headline loan amount tells you little about the company's usable cash or future obligations. Five parts of the agreement explain the financing.

1. Access to the money. A facility is the total financing available under an agreement. The company may draw it all at closing or in tranches, separate installments with their own conditions and deadlines. Undrawn, conditional money isn't cash in the bank.
2. Interest and fees. Interest may be fixed or tied to a benchmark rate, sometimes with a minimum rate. Fees charged when the loan starts, legal costs, an end-of-term fee, and charges for early repayment can add to the cost. The interest rate alone doesn't describe the full bill.
3. Repayment. An interest-only period postpones principal payments. Amortization means paying principal down over time. Some loans have a balloon payment, a larger amount due at the end. There is no single repayment schedule for every venture loan.
4. Warrants. A warrant gives its holder the right to buy shares under specified terms. Warrants can dilute existing shareholders and can remain outstanding after the loan is repaid. They are separate from converting loan principal into equity.
5. Security and covenants. Security gives a lender rights over specified collateral, assets supporting the loan. Covenants are promises or restrictions, such as reporting requirements, a minimum cash balance, or consent requirements for additional borrowing. The agreement defines default, any cure periods (time to fix a breach), and the remedies available to the lender.

A company can have cash and still breach its loan agreement. Missing a required report or violating a restriction may constitute a technical default, even without a missed payment. Orrick's discussion of venture debt defaults explains why covenant cushions and cure provisions matter. A waiver is a negotiated outcome, never something the company can assume.

A committed facility can still contain unavailable money

In its quarterly report for the quarter ended March 31, 2025, biotechnology company 89bio described a $30 million tranche contingent on clinical data by a deadline. It said changed trial timing meant it didn't expect to meet that condition. Another tranche was subject to the lenders' discretion.

The same disclosure included an end-of-term fee, prepayment charges, warrants, and minimum-liquidity requirements. Those were one company's negotiated terms, not market benchmarks. They show why an investor needs the draw conditions and payment schedule behind an announced facility.

When venture debt can help a startup

Debt can support a defined operating plan. The investor's job is to connect the use of cash with the source and timing of repayment.

Reaching a specific milestone between equity rounds

A company might use debt to finish a product launch, reach a commercial milestone, or complete work that strengthens its next financing case. More time can help when the milestone is achievable within the cash budget.

Our co-founder and general partner Elizabeth Yin writes in Democratizing Knowledge, “Your runway dictates how much you can build and tackle at each step.” An investor needs that time tied to specific progress the company can afford.

A milestone doesn't guarantee the next round or a higher valuation. A company relying on that round to repay debt has financing risk as well as operating risk. Its plan needs room for a slower fundraise, a smaller round, or a missed milestone.

Adding cushion after an equity raise

A newly funded company may arrange debt while it has cash and time to negotiate. That can add a buffer against delays and reduce the amount of equity needed immediately.

The buffer's value depends on when the company can draw it and when repayment begins. A loan with an expiring draw window or performance conditions may provide less protection than the founder expects. Debt can also add reporting, legal, and management work even when the company isn't struggling, depending on the agreement's requirements.

Funding a repeatable cash cycle

A company may spend on customer acquisition or inventory before collecting cash from customers. Debt can bridge that gap when the evidence supports the collection timing and the company can afford the payments.

Yin makes the condition explicit in Democratizing Knowledge: “Debt can be good for known retention.” Her point depends on observed customer behavior and enough capital to wait through the payback period.

A forecast that a customer will spend three times the acquisition cost over several years doesn't establish cash for next month's loan payment. How long customers stay, the cash left after serving them, collection delays, refunds, and the time to recover acquisition spending all affect repayment capacity.

A profitable company may also have access to conventional loans based on its operating cash flow, customer payments owed to it, or equipment purchases. Venture debt isn't automatically its cheapest option. Compare the complete terms and the use of cash rather than treating lower immediate dilution as the whole decision.

Calculate runway after debt payments

Adding the loan amount to cash and dividing by the old burn rate overstates runway when it ignores fees, repayment, or required cash reserves. Net burn is the cash a company spends beyond what it collects over a period.

Consider a hypothetical, simplified company cash-flow example. These are invented terms, not a financing offer or a forecast:

• Starting position: $600,000 in cash and $100,000 in monthly operating net burn. Without new financing or changes in operations, cash reaches zero after six months.
• Loan: $600,000 drawn immediately, with a 2% upfront fee. Cash after the fee is $1,188,000.
• Interest-only period: Six months at a fixed 12% annual rate, calculated monthly on outstanding principal. Interest is $6,000 per month, so total monthly cash outflow is $106,000.
• Principal payments: Starting in month seven, principal is repaid in 24 equal monthly installments of $25,000. The first payment month has $6,000 in interest plus $25,000 in principal. Total cash outflow that month is $131,000. Interest falls as principal is repaid.
• Cash covenant: The company must maintain $100,000 in cash. Its financing plan needs to act before that threshold, even though the bank account isn't empty.

After the first six months, cash is $552,000: $1,188,000 minus six payments of $106,000. Only $452,000 remains above the cash floor, and the company still owes the full $600,000 principal. The calculation excludes other fees, legal costs, taxes, investment income, and changes in operating cash flow.

The loan adds time, but the company enters month seven with a higher cash burden. A forecast that leaves monthly burn at $100,000 misses the principal-payment step entirely.

An investor should have three versions of the monthly cash plan: the operating plan, slower collections or growth, and a delayed next equity round. Each needs the actual loan payments, draw restrictions, and covenant thresholds. The repayment source should be named in each version.

Red flags for an equity investor

The most useful warning signs concern assumptions that can fail together.

• The next round pays for everything. Revenue is behind plan, principal payments are approaching, and repayment depends on new investors arriving on schedule. Slower growth may also make that financing harder to secure.
• Investor support is described as committed cash. An existing investor's willingness or capacity to help isn't a binding financing commitment. A recognizable name on the cap table, the company's record of ownership and securities, doesn't pay the next installment.
• Conditional tranches fund the downside case. The company assumes it can draw more money even if it misses the performance conditions required for that draw.
• Payments start before customer cash arrives. Attractive long-term economics can coexist with a near-term cash shortfall. The cash schedule needs to include the wait between spending and collecting.
• Covenants leave little room for error. A minimum-cash requirement or operating restriction can force negotiations while the founder still thinks the company has plenty of runway.
• New equity largely repays old debt. That may be necessary, but it changes what your check funds. Money going to creditors buys less new operating progress than the headline equity raise suggests.

Borrowing doesn't improve weak retention, unprofitable sales, or a product customers don't want on its own. A lender's approval also doesn't establish that the equity is an attractive investment. Lenders and shareholders have different claims and different ways to get paid.

We use education and peer discussion in Angel Squad to help aspiring and active angels form their own investment judgment. An operator who understands customer collections may spot a cash-timing assumption that another investor misses. That conversation supports diligence; it doesn't replace independent legal or financial review.

What debt changes at an exit

Debt can reduce the proceeds left for shareholders. In a sale or wind-down, outstanding principal, accrued interest, contractual fees, and other liabilities may need to be paid before proceeds reach the equity holders.

A lender's priority doesn't guarantee recovery. Collateral, the priority of legal claims against it, other creditors, transaction structure, and applicable law affect the outcome. An equity investor's liquidation preference is a contractual right for certain shareholders to receive proceeds before other shareholders. It doesn't erase creditors' claims. Our liquidation preference guide explains that distinction.

Warrants can also change the number of shares participating in an exit. Paying off the loan may leave the warrant outstanding, depending on its terms. Your ownership percentage and the cash available to equity are separate parts of the payout calculation.

Make the loan part of your investment decision

Before an initial check or a follow-on investment in a company you already back, put five answers in your investment memo:

1. What operating progress will the borrowed cash fund?
2. How much is drawn, and what conditions apply to the rest?
3. When do principal payments begin, and how much cash must remain?
4. What pays off the loan if the next round is delayed?
5. How do fees, lender rights, and warrants affect the equity you're buying?
