What venture debt actually is
It’s a senior loan from a specialised lender — Silicon Valley Bank (before its collapse), Hercules, Western Technology Investment, TriplePoint, or similar — typically sized at 25–35% of your last equity round. The structure: a 3–4 year term, monthly interest-only payments for the first 12–18 months, principal repayment after, and warrants covering 0.5–2% of equity on top. It looks cheap because the headline interest rate is in the single digits. It is not cheap once you factor in everything.
Where it works
Venture debt makes sense when:
- You have a clear path to the next equity round and need to bridge 6–12 months of runway without taking a flat or down round at current market conditions.
- You have predictable, contracted revenue — SaaS with annual contracts, marketplaces with GMV visibility — and lenders can underwrite against your ARR with confidence.
- You’re using the debt to fund a specific growth experiment with a measurable payback period inside 12 months: a new sales hire, a marketing channel test, a geographic expansion.
- Your existing investors are supportive — lenders almost always want to see lead investor alignment, and some require a formal comfort letter.
Where it kills you
Venture debt kills you when:
- You take it to extend a company that doesn’t actually have product-market fit. You’re just buying expensive time while the core problem stays unsolved. The interest payments start immediately; the growth doesn’t.
- You hit a covenant you didn’t read carefully. MAC (material adverse change) clauses, cash minimum requirements, ARR growth thresholds — trip any one of them and the lender can call the loan. In a down market, lenders do exercise these rights.
- You stack it on top of a SAFE-heavy cap table. The next round’s investors see senior debt plus uncapped SAFEs sitting ahead of their equity — and the combination is often a deal-killer.
- You use it as a signal of confidence without actually having the equity round lined up. Debt is not a substitute for a priced round; it’s a bridge to one.
The real cost
Factor in warrants, origination fees, legal costs on both sides, and the interest, and “cheap” venture debt typically runs 12–18% all-in on an annualised basis. That’s fine if the capital produces a 2x or better valuation step at the next round. It’s catastrophic if it just delays the reckoning by six months while burning through your remaining optionality.
What this means for you
Never take venture debt to survive. Take it to accelerate something that’s already working. The question to ask the lender — and yourself — before signing: “What happens to this company if my next equity round is six months late?” If the honest answer is “we default,” don’t sign.
Frequently Asked Questions
Q: How much venture debt can a startup typically raise relative to its last equity round? A: Venture debt is typically sized at 25–35% of the most recent equity round. A company that raised a $10M Series A can generally access $2.5M–$3.5M in venture debt, with final terms depending on ARR predictability, covenant structure, and lead investor support.
Q: What are typical venture debt covenants startups should watch for? A: Key covenants include minimum cash balance requirements (often 3–6 months of burn), ARR growth thresholds (typically 20–30% year-over-year), material adverse change (MAC) clauses giving lenders discretion to call the loan, and restrictions on additional debt or equity dilution above certain thresholds. Tripping any single covenant in a down market gives the lender legal grounds to demand immediate repayment.
Q: What is the all-in cost of venture debt when warrants and fees are included? A: After adding warrant coverage of 0.5–2% of equity, origination fees of 0.5–1% of principal, legal fees on both sides, and an interest rate in the 8–12% range, venture debt typically runs 12–18% on an annualised all-in basis — comparable to convertible notes but with senior repayment priority and none of the equity upside.
Q: How does venture debt affect the next equity round? A: Senior venture debt sitting on a cap table ahead of new equity makes the company less attractive to incoming investors, who see their capital at risk if the debt covenants are tripped. A combination of uncapped SAFEs plus venture debt is particularly problematic because it creates multiple layers of priority claims ahead of the new investor’s equity — a structure that frequently delays or kills Series A term sheets.
Q: What is a MAC clause in a venture debt agreement? A: A Material Adverse Change (MAC) clause allows the lender to call the loan immediately — demanding full repayment — if the company experiences a material deterioration in business condition, financial position, or prospects. “Material” is defined broadly and subjectively, giving lenders significant discretion during periods of market stress. Silicon Valley Bank exercised MAC clauses on several portfolio companies in its final weeks before its 2023 collapse.
