What Is Venture Debt? Definition, How It Works and Examples

What is venture debt and how does it work in practice? A startup raises money in two ways. With equity, it sells shares, and the buyers own part of the company for good. With debt, it borrows and pays the money back with interest. Venture debt financing is the second kind, made for companies that do not yet earn steady profits. Hercules Capital, one lender, says traditional lenders have generally underserved such companies. A venture lender leans on the backing of the company’s venture capital investors and their plans to put in more money.

The trade is simple. Debt costs interest and must be repaid on schedule. Equity costs ownership. Each new share lowers the stake of every existing holder, an effect called dilution. Hercules Capital, which lends to venture-backed companies, describes its loans as less dilutive than equity and a complement to it. Venture debt is one part of private credit, the wider market of lending outside banks and public bonds.

A lender is most willing to lend soon after an equity round, while investors’ money is still in the bank. The loan gives the company more months of cash before the next round. That time can be used to reach a goal that supports a higher price for new shares, such as a revenue target or a product launch.

• More time between roundsThe company keeps operating longer before it has to raise equity again.
• Buying equipment or funding growthSpending that pays back over time, such as hardware, labs or sales hires.
• A bufferCash on hand in case the next round takes longer than planned.

Venture debt is a poor fit for a company with no clear path to its next round. The loan has to be repaid whether or not new money arrives.

Hercules Capital is a business development company that lends to venture-backed companies, and its annual report to the SEC describes its loans. They run for two to five years. As of December 31, 2025, their interest rates ranged from about 7% to 14%, and 97.9% of them floated with a market rate. Many start with an interest-only period of three to eighteen months, when the company pays interest but repays none of the loan.

Interest is only part of the cost. The same loans can carry fees at the start, at the end and on early repayment. Some carry PIK interest, short for payment in kind, which is added to the loan in place of cash. Most important for shareholders, the lender often takes warrants. A warrant lets the lender buy a set number of shares at a fixed price later. If the company does well, the warrants can be worth far more than the interest.

The lender also takes security. In many cases, it has the first claim on all of the company’s assets. Sometimes the company instead promises not to pledge its intellectual property, such as patents and code, to another lender. That promise is called a negative pledge. Some loans also require the company to keep a minimum amount of cash.

A facility is a promise to lend up to a set amount, which the company draws in parts. Part of it may be available at once. Other parts may open only when the company hits agreed milestones. Hercules reports about $385.6 million of commitments it had not yet funded at the end of 2025, and some depend on such milestones.

A facility is a promise with conditions. The lender’s agreements let it stop funding if the company suffers a materially adverse event, such as a sharp fall in its business. So the undrawn part of a facility can disappear just when the company needs it.

A company has just closed a Series B round at $4.00 a share. It borrows $10 million for 36 months. For the first 12 months it pays only interest. Then it repays the loan in 24 equal monthly parts. The lender also gets warrants to buy 50,000 shares at $4.00.

The loan costs about $2.55 million in interest and fees. The warrants add 50,000 shares to the company’s count. Raising the same $10 million in equity at $4.00 would mean 2,500,000 new shares, 50 times as many. If the company is later sold at $20 a share, the warrants are worth $16 a share, or $800,000. If the company cannot raise its next round, the full $10 million is still owed, and the lender’s claim on the assets comes ahead of every shareholder.

A venture debt fund pools money from investors and lends it to venture-backed companies. Investors receive a share of the interest, fees and warrant gains, after the fund’s own costs. Some lenders are private funds open only to qualified investors. Others are business development companies (BDCs), regulated funds that must keep at least 70% of their assets in qualifying investments, mainly US private companies. Hercules Capital is one, and it files annual reports with the SEC.

The lender’s risk is the borrower’s. Many of these companies do not yet make a profit, so repayment often depends on the next equity round or a sale. Direct lending applies the same idea to mid-sized companies, often owned by private equity firms.

• Counting on the next roundThe loan is due on schedule even if new money never arrives. A missed round can hand the assets to the lender.
• Treating undrawn money as cashParts of a facility can depend on milestones, and the lender can stop funding after a serious setback.
• Looking only at the interest rateFees, PIK interest and warrants all add to the cost.
• Forgetting the warrants on the cap tableThey are small, but they are future shares. Count them when you work out your stake.
• Assuming shareholders are paid firstLenders are repaid before any shareholder in a sale or a shutdown.
