Convertible Notes Explained
- A convertible note is debt that converts to equity at a future priced round, typically carrying a 4-8% annual interest rate (median about 7% in 2025) and a 12-24 month maturity date
- Notes include a valuation cap (maximum conversion price) and/or a discount (typically 15-25%) to reward early investors for higher risk
- At maturity, if no priced round has occurred, the note may convert at the cap, become payable as debt, or be extended by mutual agreement
- Interest accrues and converts to additional equity at the conversion event, slightly increasing investor ownership beyond the principal amount
