This article is for VC-backed startup founders who are considering venture debt but aren't sure if it's right for their company or how it actually works.
If you're wondering when to raise venture debt, how it differs from a bank loan, or what covenants and warrants actually mean for your business, this guide covers the structure of venture debt deals, the scenarios where it adds real value, and the legal restrictions you need to watch out for.
Key Takeaways
• Raise venture debt immediately after closing an equity round when you have leverage, not when running out of cash.
• Expect loan amounts of 20% to 35% of your last equity round at 12% to 18% interest rates.
• Warrants typically require 5% to 20% of the loan amount in equity rights, creating minor dilution.
• Breaching financial covenants like minimum cash balances can trigger immediate full loan repayment demands.
• Change of control clauses may require full repayment upon acquisition, potentially blocking or delaying deals.

What Is Venture Debt?
Venture debt is a loan product built for high-growth startups, not traditional businesses. Unlike a standard bank loan, it does not require you to be profitable or have significant assets.
Instead, lenders rely on your investor backing, your revenue trajectory, and your ability to raise future equity rounds as security.
In practice, this means venture debt providers are betting on your next funding round, not your current cash position.
How Is Venture Debt Different from a Bank Loan?
Traditional banks lend against assets, profitability, and credit history. Venture debt lenders lend against growth potential, investor quality, and your funding history.
That distinction matters enormously for pre-profit startups.
For venture debt VC-backed start-ups generally qualify, the security required is covenants, the typical interest rate is 12% to 18% per year and venture debt does not require the company to be profitable.
For a bank loan a profitable business will qualify, the security required is assets or guarantees, the typical interest rate is 4% to 8% per year and obtaining a bank loan usually requires a company to be profitable.
When Does Venture Debt Make Sense?
Venture debt works best as a bridge, not a lifeline. The optimal time to raise it is after closing an equity round, not when you are running out of cash. Set out below are the scenarios where venture debt genuinely adds value.
Extending Runway Between Equity Rounds
You raised a Series A and want to hit a key milestone before raising your Series B. Venture debt can add 6 to 12 months of runway without giving away more equity at your current valuation.
It is important to raise venture debt when you have leverage, meaning shortly after closing equity, not when your runway is already short.
Funding Working Capital or Equipment
If you need to invest in physical assets, inventory, or specific infrastructure, debt can be cheaper than equity. This is especially true if you have predictable revenue to support repayments. In this instance venture debt will genuinely add value.
Avoiding Dilution at a Low Valuation
Raising equity at an unfavourable valuation can significantly dilute founders and early investors. Venture debt lets you defer that equity raise until your valuation improves. It therefore avoids dilution when you are at a low valuation.
How Are Venture Debt Deals Structured?
A typical venture debt deal has two core components: the loan itself, and warrants. Both of these elements are explained below.
The Loan Component
- Loan amounts typically range from 20% to 35% of your most recent equity round. So if you raised a €3 million Series A, expect to be offered €600,000 to €1 million in venture debt.
- The loan usually comes with an interest-only period of 6 to 12 months, followed by principal repayments over 24 to 36 months.
- Interest rates generally run between 12% and 18% per year, though this varies by lender and risk profile.
What Are Warrants?
Warrants give the lender the right to buy equity in your company at a fixed price in the future.
They are typically set at 5% to 20% of the loan amount, giving the lender a small equity position as upside.
For example: a €500,000 loan with 10% warrant coverage means the lender gets the right to buy €50,000 worth of your equity at today's price.
Warrants are dilutive, but far less so than raising a full equity round. This is the trade-off that makes venture debt attractive.
What Covenants and Restrictions Do Lenders Impose?
This is the part most founders underestimate. Venture debt comes with legal strings attached.
Covenants are contractual obligations you must maintain throughout the loan period. Breaching them can trigger early repayment demands. Common financial covenants and common operational restrictions are set out below.
Common Financial Covenants
- Minimum cash balance (e.g., you must maintain at least 3 months of operating expenses in the bank)
- Minimum monthly recurring revenue (MRR) targets
- Revenue growth thresholds tied to repayment schedules
- Restrictions on taking on additional debt without lender consent
Common Operational Restrictions
- Lender approval required before making large acquisitions
- Restrictions on paying dividends or returning capital to shareholders
- Obligation to notify lender of material changes in the business
- Change of control provisions (the loan may become repayable if you are acquired)
In our experience change of control clauses are particularly important for startups that might be acquired. A potential acquirer will review your venture debt terms closely and complicated covenants can slow or even block a deal.
What Triggers Early Repayment?
Lenders can demand early repayment in certain situations, these are called acceleration events. The events that trigger early repayment of the debt are set out below:
- Breach of a financial covenant (e.g., cash falls below the minimum)
- Insolvency or liquidation proceedings
- Material adverse change in the business
- Failure to raise a follow-on equity round within an agreed timeframe
- Misrepresentation in the loan application
Make sure that you read every covenant carefully before signing. Ask your lender exactly what triggers early repayment of the debt and negotiate tighter definitions where possible.
When Does Venture Debt Help Your Startup?
Venture debt works best when your company has strong fundamentals and is simply looking to extend runway.
Here are the signals that suggest venture debt is the right move:
- You have just closed an equity round and have 18+ months of runway
- You have predictable, recurring revenue that can service the debt
- You are approaching a clear milestone that will justify a higher valuation
- Your existing investors support the decision and may participate in the process
- You need capital for a specific purpose (equipment, hiring, geographic expansion) rather than general burn
