Compare venture debt and equity financing — cost of capital, warrants, covenants, and when to layer debt on top of an equity round.

Venture Debt vs Equity: When to Layer Debt (2026)

Venture debt isn't a substitute for equity — it's a runway extension after a priced round. Used right, it adds 4-6 months without dilution. Used wrong, it accelerates the failure.

Venture debt fits when

You've just closed a Series A or B, have 12+ months of equity runway, and want to extend before the next round. Typical size: 25-35% of the last equity round.

Equity fits when

You need real capital to fund the next milestone, or you have no revenue predictability to service debt payments.

Terms to negotiate

Interest 8-12%, warrant coverage 1-3%, 36-48 month amortization with a 6-12 month interest-only period. Watch for MAC clauses and financial covenants.
