TL;DR
Venture debt is a specialized loan for venture-backed startups that extends runway between equity rounds. While it minimizes dilution, it introduces structural risks like warrants and financial covenants. This guide deconstructs the mechanics, costs, and modern alternatives.
What is venture debt?
Venture debt (also known as venture lending) is a type of debt financing provided to early and growth-stage companies that have already secured institutional venture capital. Unlike traditional commercial loans that require physical collateral or positive EBITDA, venture debt is underwritten based on Equity Signals and the company's ability to raise a subsequent funding round.
The Role in the Capital Stack
Venture debt is not a replacement for equity; it is a Complementary Instrument. It typically accounts for 10%–20% of a company’s total funding and is used to lower the Weighted Average Cost of Capital (WACC).
How venture debt works: The 4 mechanical pillars
To optimize a venture debt term sheet, founders must understand the interplay of these four technical components:
1. Interest Rates & Benchmarks
Most venture debt in 2026 is priced as a "Floating Rate."
- The Formula: $Benchmark Rate (e.g., SOFR or Prime) + Spread (usually 6-9\%)$
- The Structure: Typically includes a 6–12 month Interest-Only (I/O) period followed by 24–36 months of principal amortization.
2. Warrants (The Equity Kicker)
Lenders use warrants to capture upside in exchange for the risk of lending to loss-making startups.
- Warrant Coverage: Usually 1% to 5% of the loan principal.
- The Impact: If you take a £5M loan, the lender gets the right to buy £100k of shares at your last round's price. At exit, this can cost founders millions in "hidden" dilution.
3. Fees (The Hidden APR)
The headline interest rate is rarely the true cost. CFOs must account for:
- Facility Fee: 1%–2% paid at closing.
- End-of-Term Fee (Exit Fee): 3%–7% of the total loan amount, paid when the loan is retired.
- Unused Line Fee: 0.5%–1% charged on capital you have not yet drawn.
4. Security & Seniority
Venture debt is Senior Secured Debt. The lender takes a "First Lien" on all company assets, including your Intellectual Property (IP). In a liquidation event, the debt provider is paid before any preferred or common shareholders.
Financial covenants: The "Hidden" risks of venture debt
Covenants are contractual tripwires designed to protect the lender. Violating a covenant triggers a "Technical Default."
- Liquidity Covenants:
Requires you to maintain a minimum cash balance (e.g., £2M or 6 months of burn).
- Performance Covenants:
Requires you to hit a percentage of your board-approved revenue plan.
- Negative Pledges:
Restrictions on taking additional debt or selling company assets without permission.
- MAC Clause (Material Adverse Change):
A subjective clause allowing the lender to call the loan if they perceive a significant downturn in your business prospects.

Choose venture debt if:
- You are buying another company (M&A) and need a large, one-time cash injection.
- You need to buy physical hardware or infrastructure.
- You just closed a major VC round and want to "stack" an insurance buffer.
Choose a Float facility if:
- You want to fund Sales & Marketing without giving up warrants.
- You need a flexible credit line that grows as your Annual Recurring Revenue (ARR) grows.
- You want to avoid the "Amortization Cliff" where high principal payments drain your runway.
FAQs
Is venture debt "Senior" to my VCs?
Yes. Debt sits at the top of the waterfall. In an exit or liquidation, the debt provider is paid in full before any investor or founder receives proceeds.
What is warrant coverage?
It is a "success fee" for the lender. It gives them the right to buy equity in your company at a fixed price. It means the loan is not truly non-dilutive.
Does venture debt require a personal guarantee?
In the venture-backed world, No. Lenders rely on the institutional backing of your VCs. If a lender asks for a personal guarantee, it is a red flag.
