Venture debt is lending to companies backed by venture capital (VC) investors, often before they are profitable. Growth debt is similar lending to later-stage companies that have more revenue but may still burn cash. A cash flow lender looks at EBITDA; many of these borrowers have negative EBITDA. So the lender relies on something else: the company's growth, its assets such as intellectual property, and above all its ability to raise more equity.
For analysts, venture debt calls for different tools: runway instead of leverage, and a view on the equity investors instead of a sponsor. For LP-side analysts and IR teams, it explains why these funds combine loan interest with warrants, and why their results can depend on the health of the venture capital market.
Why venture-backed companies borrow
A venture-backed company funds itself mainly by selling shares. Each round dilutes existing owners. Debt is a way to extend the time until the next equity round, or to fund growth, without giving away as much ownership. Founders and VC investors commonly use it to:
- extend the company's cash runway, so it can hit milestones before raising again at a higher valuation
- fund equipment, acquisitions or working capital
- give a cushion in case the next round takes longer than planned
The lender is betting that the company will reach its next funding, a sale, or profitability before the loan comes due.
How repayment works
Unlike a mature company, a venture-backed borrower often can't repay from its own cash flow. Repayment commonly comes from:
- a new equity round, part of which repays or refinances the loan
- a sale of the company to a larger buyer
- in time, the company's own profits
This makes the quality of the equity investors central. Established VC firms with capital to deploy are more likely to support a portfolio company through a difficult period. Venture lenders commonly track which investors back a company, how much they have left to invest, and whether they have supported companies in the past. That support is never guaranteed: investors can and do decide to stop funding a company.
Key terms of a venture loan
Venture loans are commonly senior secured term loans, secured on the company's assets, sometimes including its intellectual property. Common features:
| Feature | What it does |
|---|---|
| Interest-only period | The borrower pays only interest for an initial period, often a year or more, preserving cash |
| Amortization | After the interest-only period, principal is repaid in installments until maturity |
| Warrants | Rights to buy shares at a set price, giving the lender some equity upside |
| Fees | Upfront fees and often a final payment at maturity, adding to the lender's yield |
| Runway or liquidity covenants | A minimum level of cash or months of runway, rather than a leverage test |
For example, if a $15m loan has an interest-only period and then amortizes evenly over 24 months, the borrower repays $15m ÷ 24 = $0.625m of principal a month after the interest-only period ends.
Some venture loans have few financial covenants, relying instead on material adverse change clauses and close reporting. Others test revenue against plan.
Warrants and warrant coverage
A warrant gives the lender the right to buy shares at a set strike price, usually the price of the company's latest equity round. If the company's value rises, the warrant becomes valuable. If the company fails, the warrant is worthless, but it cost the lender nothing up front beyond accepting slightly lower loan pricing.
The size of a warrant is commonly expressed as warrant coverage: a percentage of the loan amount.
Warrant value at the strike price = loan amount × warrant coverage
Warrant coverage is not a percentage of the company. It says how much equity, measured at the strike price, the lender can buy.
A worked example: Lumenfield Analytics
The following example is illustrative. Lumenfield Analytics is a fictional venture-backed software company. Hollin Bay Capital provides a $15m senior secured term loan with 5% warrant coverage.
| Amount | |
|---|---|
| Loan amount | $15m |
| × Warrant coverage | 5% |
| Warrants over equity at the strike price | $0.75m |
If Lumenfield's latest round priced its shares at $2.50, the warrants cover $0.75m ÷ $2.50 = 300,000 shares. If those shares are later worth $7.50, each warrant is worth $7.50 − $2.50 = $5.00, and the warrants together are worth 300,000 × $5.00 = $1.5m. If the shares are worth $2.50 or less, the warrants are worth nothing.
The loan's interest and fees are the core of the return. Warrants add upside across a portfolio: most may expire worthless or modestly valuable, while a few successful companies can add meaningfully to the fund's result.
Runway covenants
Because leverage ratios make little sense for a company with negative EBITDA, venture lenders commonly focus on cash runway:
Runway (months) = cash ÷ monthly net cash burn
A borrower with $24m of cash burning $2m a month has 12 months of runway. A loan might require a minimum number of months, or a minimum cash balance. When runway gets short, the lender wants to see a credible plan for the next equity round or a sale, and may have the right to ask for early repayment.
How venture lenders lose money
Losses tend to come when a company runs out of cash and its investors decline to fund it further. The lender then relies on selling the company or its assets, including intellectual property, which may be worth far less than hoped. Because many venture-backed companies depend on the same funding environment, a slowdown in venture capital fundraising can affect many borrowers at once. Lenders try to manage this by lending conservatively relative to the company's equity value, amortizing the loan, and diversifying across companies and sectors.
Key terms
- Venture debt: lending to venture-backed companies that may not yet be profitable.
- Growth debt: similar lending to later-stage companies with more revenue that may still burn cash.
- Dilution: the reduction in existing owners' share when a company issues new shares.
- Interest-only period: an initial period when the borrower pays interest but no principal.
- Warrant: a right to buy shares at a set strike price.
- Warrant coverage: warrant size expressed as a percentage of the loan amount.
- Cash runway: how many months a company can operate on its cash at its current burn rate.
Key takeaways
- Venture debt lends to companies that may not be profitable; repayment often depends on future equity raises or a sale.
- The quality and commitment of the equity investors is central to the credit decision.
- Interest-only periods, fees and warrants shape the lender's return; covenants focus on cash runway rather than leverage.
- Lumenfield's $15m loan with 5% warrant coverage gives warrants over $0.75m of equity at the strike price.
- Losses tend to cluster when venture funding dries up, so diversification and conservative sizing matter.
