Convertible Note
Quick definition
Debt instrument that converts to equity at a future priced round; includes a valuation cap, discount, interest, and maturity date.
Convertible notes are short-term debt that accrues interest (typically 5–8% annually) and converts into equity at the next priced round, with the principal + accrued interest converting at either the valuation cap price or with a discount. Unlike SAFEs, notes have a maturity date — if no qualifying round happens by then, the note matures and must be repaid, repriced, or extended. SAFEs have largely replaced convertible notes for seed-stage financing because they're simpler.
