What is Venture Debt?
Short answer: Venture debt is lending to a venture-backed or high-growth company whose current cash flow may not support conventional cash-flow lending. Repayment often depends on existing liquidity, future equity financing, growth milestones or enterprise value. It remains debt: principal, interest and fees are payable even if the company misses its operating plan or cannot raise the expected next round.
A facility may contain delayed-draw tranches, interest-only periods, final fees, warrants, security over company assets, minimum cash covenants and material adverse change protections. Later tranches can depend on revenue, regulatory or equity milestones. The lender may size exposure relative to the recent equity round and investor support, but headline post-money valuation is not cash available for repayment. Warrants or conversion features add equity-linked economics. Compared with issuing equity immediately, debt can reduce near-term dilution but introduces fixed claims and downside enforcement rights.
How it works
Model each tranche separately. Record availability dates, draw conditions, principal, cash and capitalised interest, fees, amortisation, maturity and warrant terms. Forecast monthly cash through maturity under on-plan, delayed-round and no-new-equity cases. Calculate runway after debt service, not merely after the initial draw. Test minimum liquidity and milestone covenants at every date. Estimate warrant dilution using exercise price and underlying shares, while keeping it separate from cash debt service. Include security, subordination and lender consent requirements in the operating and fundraising timetable.
Net runway extension = debt cash received - financing fees - debt service paid during the measured runway period
Example
A company draws 3,000. It pays a 60 upfront fee, 10% annual cash interest monthly, no principal for 12 months, then repays 250 of principal monthly for 12 months, plus a 150 final fee. During the first year, cash received net of the upfront fee is 2,940 and cash interest totals about 300, so the first-year liquidity addition is about 2,640 before other costs. In the second year, principal, declining interest and the final fee require more than 3,300 of cash. If the equity round slips by six months, the facility can shorten the later runway despite extending the first year.
Why it matters
Venture debt can finance equipment, bridge milestones or add contingency liquidity between equity rounds. Management should compare it with equity using downside survival, not only immediate ownership dilution. Investors assess whether debt gives the company enough time to reach a financeable milestone and whether lender security could impair an orderly pivot or sale. Boards should preserve enough cash to service the facility without assuming a future raise. Lenders monitor sponsor support, burn, performance, capital access and collateral, with heightened attention when valuations or financing markets weaken.
Terms vary widely, and the venture label does not limit remedies. A lender may hold security over substantially all assets, require deposit control or restrict additional debt and asset sales. Warrants raise securities, valuation, tax and accounting questions. Local law controls corporate approvals, security perfection and enforcement. Financial-statement classification of warrants and fees can differ from legal form. Availability of an undrawn tranche is not certain if conditions fail. Legal, tax and accounting review is essential, and the board should document why the debt remains repayable under credible downside scenarios.
