Venture Debt Explained
January 18, 2026
Learn when venture debt extends runway without dilution, how covenants and warrant coverage work, and which lenders are active after SVB's 2023 collapse.
When Venture Debt Makes Sense
Venture debt is non-dilutive debt available to venture-backed companies, typically sized at 25 to 35 percent of the most recent equity round. A company that raised a $4M Series A can generally access $1M to $1.4M in venture debt from a specialised lender based on the credibility of the investor syndicate and the underlying business metrics. The defining characteristic is that lenders rely on the equity backers' due diligence rather than the company's assets or cash flow, which is why the product is exclusively available to funded startups.
The ideal use case is extending the runway between two priced rounds without issuing more equity. If your Series A gave you 18 months of runway and you need 24 months to hit the metrics that justify Series B terms, venture debt can bridge the gap for a fraction of the dilution cost. It is not a substitute for revenue: lenders monitor your cash position closely and a covenant breach mid-term creates operational disruption at exactly the wrong moment. Companies with flat or declining revenue should not take venture debt to mask a structural problem — the repayment obligation makes a difficult situation worse.
Covenant Structures
Covenants are contractual conditions attached to venture debt that, if violated, give the lender the right to accelerate repayment. The most common covenant is a minimum cash balance requirement — often $500,000 or a specified number of months of burn — designed to ensure the lender's collateral position does not erode to zero before they can act. Breaching a minimum cash covenant while also running low on runway is an existential event; the bank can demand repayment immediately when you can least afford it.
Revenue covenants are increasingly common in today's lending environment, typically requiring minimum ARR growth rates or absolute ARR thresholds at specified dates. A "no material adverse change" clause is nearly universal: any event that materially impairs the company's ability to repay — a key executive departure, loss of a major customer, or a regulatory action — can trigger a covenant review. Reading every covenant carefully with a startup-experienced attorney before signing is not optional. The list of startups that discovered a covenant violation during due diligence for their next round, and had to renegotiate the debt under time pressure, is long.
Warrant Coverage
Venture debt is not free money. Lenders receive warrants — the right to purchase equity at a fixed price — as compensation for the risk of lending to a company with no traditional collateral. Warrant coverage is expressed as a percentage of the loan amount and typically ranges from 10 to 20 percent. A $1M loan with 15 percent warrant coverage gives the lender warrants worth $150,000 at the exercise price, usually set at the last round's per-share price.
This is the dilution cost of venture debt: smaller than a full equity round, but not zero. On a $4M post-money valuation, $150,000 in warrants represents 3.75 percent ownership transferred to the lender. If the company's valuation grows significantly before the lender exercises, that 3.75 percent becomes more valuable — which is why warrant coverage is the primary negotiating lever in venture debt terms. Reducing warrant coverage from 20 percent to 10 percent by agreeing to stronger covenants is a common trade-off that favours founders who are confident in their covenant compliance.
Top Lenders and Terms
Silicon Valley Bank was the dominant venture debt provider before its collapse in March 2023, which left a gap in the market that competitors have since filled. Hercules Capital is now among the most active lenders for growth-stage startups, typically writing $3M to $50M facilities with interest rates at prime plus 2 to 5 percent. Western Technology Investment (WTI) focuses on earlier-stage companies and will write smaller facilities starting around $1M. Lighter Capital specialises in sub-$3M revenue-based structures for software companies that may not yet qualify for traditional venture debt.
Current interest rates make venture debt meaningfully more expensive than it was in 2020 and 2021. Prime rate plus 3 percent at a 7 percent prime means all-in interest of approximately 10 percent — still cheaper than the implied cost of equity dilution at early valuations, but a real cash obligation that needs to appear in your runway model. Evaluate venture debt by calculating the effective cost of capital against the alternative of raising more equity at your current valuation. In most seed-to-Series-A scenarios, venture debt remains dilution-efficient; in a down round, where equity is cheap, the math often reverses.
Frequently Asked Questions
What is venture debt and who qualifies? Venture debt is non-dilutive term debt available exclusively to venture-backed companies, typically sized at 25 to 35 percent of the last equity round. Qualification depends primarily on the reputation of the equity investors rather than the company's assets or current revenue.
What are common venture debt covenants? The most common covenant is a minimum cash balance requirement. Revenue covenants requiring minimum ARR growth are increasingly standard. A material adverse change clause is nearly universal and can trigger early repayment if the company experiences a significant negative event.
How does warrant coverage work in venture debt? Lenders receive warrants to buy equity at the last round's per-share price, typically at 10 to 20 percent of the loan amount. A $1M loan with 15 percent warrant coverage produces $150,000 in warrants — the dilution cost of the debt.
Which venture debt lenders are active after SVB's collapse? Hercules Capital writes $3M to $50M facilities. Western Technology Investment (WTI) works with earlier-stage companies from around $1M. Lighter Capital provides revenue-based facilities under $3M for software companies. All three are active in 2026.
Is venture debt cheaper than equity dilution? Usually yes at early valuations. A 10 percent all-in interest rate on a $1M facility costs significantly less in value transferred than issuing equity at a $5M valuation. The comparison reverses in down rounds where equity is cheap and the fixed debt obligation becomes burdensome.
