Venture Debt: What It Is and When It Makes Sense
How venture debt differs from bank loans and equity, what warrant coverage and covenants mean in practice, when venture debt helps versus when it creates risk, and what happens when things go wrong.
Venture debt is one of the most misunderstood instruments in the startup toolkit. It's neither a replacement for equity nor simply a bank loan with a different name — it's a specific product designed for VC-backed companies that have demonstrated enough traction to borrow against their future, while carrying enough risk that conventional lenders won't touch them.
Used well, venture debt extends runway cheaply and preserves equity. Used carelessly, it introduces covenants and obligations that can complicate an already difficult situation.
How Venture Debt Works
Venture debt is typically a term loan or revolving credit facility offered to VC-backed startups by specialist lenders — not banks. The main venture debt providers in Europe include Western Technology Investment (WTI), Kreos Capital, TriplePoint, Deutsche Bank's venture lending arm, and a small number of others.
The key structural features:
Size: Typically 20–35% of your most recent equity round. If you raised a €5M Series A, you might be offered €1M–€1.75M in venture debt alongside or shortly after the round.
Term: Usually 24–48 months, with an interest-only period of 6–12 months followed by principal amortization.
Interest rate: Generally 8–15% for European companies, depending on risk profile. More expensive than investment-grade corporate debt, cheaper than equity if you believe in your upside.
Warrant coverage: The equity kicker that distinguishes venture debt from bank debt. Lenders take warrants (rights to buy shares at a set price) equal to 5–20% of the loan amount. A €1M loan at 10% warrant coverage gives the lender warrants worth €100K — typically priced at the most recent round's share price.
Covenants: Financial requirements you must maintain throughout the loan term. Common covenants include minimum cash balance requirements, minimum MRR targets, and restrictions on additional debt. Breaching a covenant can trigger default even if you're making payments.
Venture Debt vs Bank Debt vs Equity
| Feature | Venture Debt | Bank Loan | Equity (Series) | |---|---|---|---| | Dilution | Minimal (warrants only) | None | Significant | | Cost | 8–15% + warrants | 4–8% | Depends on valuation | | Security | Usually all-assets | Often physical collateral | None (investors take risk) | | Covenants | Yes | Yes | None | | Default risk | Yes | Yes | None | | Availability | Post-institutional-VC | Requires solid credit history | Investor dependent | | Timeline to close | 4–8 weeks | 8–16 weeks | 3–6 months |
The dilution comparison is the main reason founders consider venture debt. If you believe your company will be worth significantly more at your next round, preserving equity now by using debt is economically rational. A warrant giving the lender the right to buy €100K in shares is much less dilutive than giving a new investor €1M in equity at the same round valuation.
When Venture Debt Makes Sense
Extending runway post-raise. The most common and defensible use: you've just closed a round, the lender trusts your investors' judgment, and the debt buys you additional runway without going back to market. This is runway insurance at a reasonable cost.
Bridging to a specific milestone. If you're six months from a revenue milestone that would meaningfully improve your Series B valuation, venture debt can get you there without diluting against your current metrics.
Financing capital expenditure. If you need hardware, equipment, or infrastructure that generates returns, debt financing this (rather than equity) is capital-structure appropriate.
Supplementing an equity round. Some founders raise a smaller equity round supplemented by venture debt to hit a larger total capital number — particularly when they want to limit dilution or when the equity market is expensive.
When Venture Debt Creates Risk
You're already struggling. Venture debt makes problems worse, not better. A company burning €250K/month with 8 months of runway should not take on a debt facility with minimum cash covenants. If your MRR drops and you breach a covenant while sitting on debt, the situation escalates quickly.
You don't have institutional investors. Venture debt lenders co-underwrite with your equity investors. If you don't have established VCs on your cap table who know how to navigate a distressed situation, lenders are taking on more risk and will price accordingly — or won't lend at all.
You don't understand the covenants. Minimum cash covenants are the most dangerous. If a lender requires you to maintain €500K in cash at all times and your cash dips below that threshold (even temporarily, even if you're making payments), you're in technical default. Read every covenant carefully before signing.
The business model doesn't support debt service. If you're in a high-growth, high-burn mode where you won't generate positive cash flow for 3+ years, monthly debt service is a real drain. Model what loan repayments look like against your projected cash position in the conservative scenario.
What Happens When Things Go Wrong
Venture debt lenders are not equity investors. They have loan documents with legal remedies. If you breach a covenant or miss payments, the lender's options include:
- Demanding immediate repayment of the full balance
- Taking control of pledged assets (venture debt is often secured against all company assets)
- Blocking distributions or further borrowing
In practice, most venture debt lenders prefer to work out a solution rather than liquidate — the recovery on a fire-sale of startup assets is terrible. But the negotiations are difficult, often require investor involvement, and consume enormous founder time and energy during an already stressful period.
The cautionary tale that repeats in the market: a company takes venture debt, hits a rough patch, breaches a covenant, and ends up in a workout negotiation that distracts the founders, damages investor confidence, and produces a bad outcome for everyone.
Venture debt is a useful tool for companies in a strong position who want to optimize their capital structure. It's a dangerous tool for companies using it to buy time when the fundamentals haven't worked. Getting an honest read on which situation you're in — before signing — is worth significant effort; founders who work through this with advisors who have been on both sides of venture debt decisions, through a network or a platform like Founderboard, are better positioned to make the call with clear eyes.
