Venture debt for startups: how it works and when it fits

Venture debt is a loan made to a startup that has raised, or is raising, venture capital, usually a term loan with an interest-only period, warrants, fees and covenants. It comes from venture lending teams at banks and from specialist non-bank lenders. It can stretch runway without selling more of the company, but it comes with a repayment schedule, conditions and a lender who can act if things go wrong. This guide is for seed to Series B founders weighing a facility alongside, or instead of, more equity.

What venture debt is and who provides it

Venture debt is designed for companies that do not yet qualify for a conventional bank loan. A traditional lender looks for profits, hard assets or a long operating history, and a startup usually has none of those. What it does have is recent equity backing, a growth plan and investors who may support it again. Venture lenders lend against that picture: the equity round supplies cash to repay the debt and a signal that sophisticated investors have underwritten the business.

Providers fall into two broad groups:

• Banks with technology or venture lending teams, which often pair the loan with a deposit and operating account relationship.
• Non-bank lenders, such as specialist venture lending funds and credit funds, which may offer more flexibility on structure in exchange for different pricing and terms.

Terms vary widely between and within these groups, so compare actual term sheets rather than assuming one lender's structure is the market.

How venture debt works: common structures and terms

Every facility is negotiated, but most are built from the same parts.

Term loans and draw periods

The most common form is a term loan: a fixed amount, borrowed at once or drawn in tranches over a set window. Later tranches are sometimes conditioned on milestones, such as closing the next equity round or reaching a revenue level. A tranche the company cannot draw when it needs it is not runway, so read the conditions as carefully as the headline amount.

Interest-only periods and amortization

Many loans start with an interest-only period, when the company pays interest but no principal. Hercules Capital's 10-K describes interest-only periods of three to eighteen months or longer on its loans. After that, amortization begins: monthly payments of principal plus interest until the loan is repaid. The amortization start date is the number to plan around, because that is when monthly cash out steps up sharply.

Warrants

Lenders often receive warrants: the right to buy a small amount of company stock at a set price in the future. Warrants let the lender share in the upside and are a form of dilution, usually much smaller than an equity round, but they belong in the cap table model from day one.

Fees

Expect some combination of upfront or commitment fees, fees on unused amounts, a final payment due at maturity, and prepayment fees for repaying early. Add them up across the life of the loan; the headline interest rate is only part of the cost.

Covenants

Venture debt covenants are promises the company makes for as long as the loan is outstanding. Breaking one is usually an event of default, even if every payment has been made on time, so covenants deserve as much attention as the rate. They fall into three groups:

• Financial covenants, such as keeping a minimum cash balance or meeting revenue or performance tests against the plan.
• Reporting covenants, such as delivering monthly financials, compliance certificates and the annual budget on a schedule.
• Restrictions (negative covenants) on taking on other debt, selling assets, paying dividends or making acquisitions without the lender's consent.

Some facilities, often called covenant-light, have few or no financial covenants and rely on other protections. Others have tight ones. Both can work, as long as the founder knows which one the company has.

Common venture debt covenants

The table describes the covenants founders most often meet in venture loan agreements. Names, definitions and thresholds are negotiated in every deal, so the structures below are typical shapes, not market terms.

An illustrative covenant headroom example

Headroom is the gap between where a covenant measure stands and where it would be breached. A company in this example has a minimum cash covenant of 1,000 and a revenue covenant requiring trailing three-month revenue of at least 80% of plan. It burns 300 a month.

Illustrative figures, not client data.

The cash line looks comfortable, but time matters more than size. At 300 a month of burn, 900 of headroom lasts three months (900 / 300), while cash itself would last about six (1,900 / 300 = 6.3). The covenant, not the bank balance, sets the deadline for raising, cutting costs or talking to the lender. The revenue line has less room: trailing revenue at 88% of plan (1,320 / 1,500) can fall only about 9% (120 / 1,320) before it breaches, so one slipped renewal could be enough.

Track both every month, in the base and the downside case, and note the first month either line gets thin.

What happens if a covenant is breached

A breach usually gives the lender the right to declare a default, which can mean a higher default interest rate, a stop on further draws and, at worst, the right to demand repayment. In practice, many breaches end in a negotiated waiver or amendment, often with a fee, tighter terms or new conditions. A company that raises a likely breach early, with a forecast and a plan, negotiates from a far stronger position than one the lender catches by surprise.

Material adverse change clauses

Many loan agreements let the lender declare a default if a material adverse change occurs in the business. The definition is often broad, so founders should review with counsel what it covers and how it affects the right to draw future tranches.

Venture debt interest rates and total cost

The interest rate is the most visible part of the price, and rarely the whole of it. Most venture loans carry a floating rate: a benchmark such as the prime rate or SOFR, plus a spread, usually with a floor below which the rate cannot fall.

One published reference point comes from Hercules Capital, a large venture lender whose annual report is filed with the SEC. Its 10-K for 2025 states that its debt investments carried contractual interest rates that generally ranged from approximately 7% to 14% as of December 31, 2025, and that 97.9% of its loans were at floating rates or floating rates with a floor. That is one lender's portfolio, not a market quote, and the rate a given company is offered depends on its stage, investors, revenue and the size and structure of the loan.

The total cost is the rate plus everything else in the agreement:

• Interest. Paid monthly, on the full balance during the interest-only period and on a declining balance once amortization starts. With a floating rate, the cost moves with the benchmark.
• Fees. Hercules lists exit fees, balloon payment fees, commitment fees, success fees and prepayment fees among the charges its loans generally include. Its weighted average effective yield on debt investments, which counts fee income as well as interest, was 12.9% in 2025.
• Warrants. Hercules reports warrant coverage that generally ranges from 3% to 20% of the principal amount, with a strike price generally equal to the most recent equity round. Warrants cost nothing in cash but are paid for in ownership if the company does well.
• Prepayment. Repaying early, for example after a new round or a sale, can trigger a prepayment fee, so the cheapest loan on paper can be expensive to exit.

To compare offers, put each one into the operating model with its draw schedule, rate, fees and warrants, and compare total cash cost and dilution side by side. A lower headline rate with a large final payment and generous warrants can cost more than a higher rate with neither.

Venture debt vs equity

The trade is simple to state and harder to weigh.

Equity is expensive in ownership but forgiving when the plan slips. Debt is cheap in ownership but unforgiving: payments are due whether or not the quarter went well. Venture debt reduces dilution only if the company can comfortably service it under realistic downside conditions.

When venture debt makes sense, and when it does not

Situations where it can fit

• Extending runway between rounds. Added months can let a company reach a milestone that supports a better next round.
• Financing a specific, predictable use. Equipment, a defined expansion or a project with a clear cash payback.
• Insurance on a plan that is already working. A cushion against slower collections or a delayed close, with a clear path to repayment.

Situations where it usually does not

• As a substitute for equity the business needs. If the company has not found a repeatable way to grow, debt shortens the time to resolve that, because repayment starts on a fixed date.
• When the forecast is uncertain. If the downside case breaks covenants, the debt adds risk rather than removing it.
• When the next round is the only way to repay it. Debt that depends on a raise closing on time makes the raise more urgent, not less.

How lenders evaluate a company

A venture lender is not betting on upside the way an equity investor is. Its question is narrower: will this company repay, and if it struggles, how will the lender recover the money?

• Investor backing. Who invested, how recently, how much cash they still have to deploy and whether they are likely to support the company again.
• Cash and runway. How long the company can operate on its current cash, with and without the loan, and how that changes in a slower case. See burn rate and runway for how to calculate it.
• Revenue quality. For SaaS, recurring revenue, net revenue retention and customer concentration, because predictable revenue makes repayment more predictable.
• Burn and its trend. Whether spending is under control and whether the path to the next milestone is funded.
• The quality of the finance function. Whether monthly numbers are timely, consistent and tie to the bank. A lender will rely on that reporting for years.

How to prepare for a venture debt facility

Model debt service under base and downside cases

Add the loan to the operating model month by month: proceeds, fees, interest during the interest-only period, then principal and interest once amortization starts. Run the base case and at least one downside case with slower growth or later collections. The downside case answers the question that matters: can the company make every payment and stay inside its covenants if the plan slips?

Measure covenant headroom

For each financial covenant, calculate the gap between the forecast and the threshold every month. Note the first month headroom gets thin in the downside case. That month is the real deadline for raising, cutting or renegotiating.

Build a reliable cash forecast

A 13-week cash flow forecast shows near-term pressure that a monthly model can miss, especially around payroll dates, large annual invoices and the first amortization payment. Decipher's free tools include a cash flow template built for this.

Prepare the data room

Have monthly financial statements, the operating model, the cap table, key customer contracts, the board deck and recent investor updates organized before the first lender conversation. A clean data room shortens diligence and signals that reporting covenants will be met.

An illustrative example: runway with and without debt

The table below shows a company with 3,000 of cash. In the base case it burns 200 a month; in the downside case, 300. It draws a 1,200 loan at month 0 with a 12 month interest-only period and an example assumption of 12 a month in interest (12% a year, used only to make the arithmetic visible, not a market rate). The loan carries an example minimum cash covenant of 1,000. Fees and warrants are left out to keep it simple.

Illustrative figures, not client data.

In the base case, the loan does what it should. Cash at month 12 rises from 600 to 1,656, and the company still has 656 of headroom over the covenant. Without debt, base case cash runs out in month 15.

The downside case tells a different story. Without debt, cash runs out in month 10. With debt, the company still has cash at month 12, but it falls below the 1,000 covenant floor in month 11 (1,080 at the end of month 10, 768 at the end of month 11). The loan adds months of cash but only about one month before a covenant breach.

And from month 13, principal of 1,200 starts amortizing on top of interest and burn. The same loan that looks comfortable in the base case can turn a slowdown into a negotiation with the lender.

Common mistakes

• Modeling only the base case. The downside case is where the decision is made.
• Forgetting the amortization step-up. Runway measured during the interest-only period overstates how long cash lasts.
• Counting undrawn tranches as cash. A milestone-dependent tranche is not runway until drawn.
• Ignoring total cost. Fees, final payments and warrants belong in the comparison with equity.
• Not tracking headroom monthly. A covenant problem the lender spots first damages the relationship.
• Signing without counsel. Default triggers, MAC clauses and cross-default terms need a lawyer's review.

How a lender and your next investor read your debt

A lender reads the company's debt through its reporting. It wants monthly financials on time, a compliance certificate that ties to them, and a forecast that shows covenant headroom before it asks. A company that flags a tightening covenant months in advance, with a plan, is in a far better position than one that misses a test without warning.

The next investor reads the debt as part of the cap table and the use of funds. It will ask how much of the new round goes to repaying the loan, when amortization started, what warrants are outstanding, and whether any covenant was close to breach. Debt that extended runway to a strong milestone reads well. Debt that bought time without changing the trajectory reads as a warning.

Both audiences reward a company that models its debt the way they will, so their review becomes a check on work already done. Decipher's Strategic Projects include venture debt preparation, from the model to the lender conversation.
