Convertible Note

A short-term loan that converts into equity during a future funding round.

Definition

A convertible note is a debt instrument that converts into equity at a later priced round (usually Series A or seed). Key terms include: principal (the investment amount), interest rate (typically 2-8%, accrues but isn't paid), discount rate (usually 15-25% discount to the next round's price), valuation cap (maximum valuation for conversion), and maturity date (when the note must be repaid or converted).

Convertible notes were the standard early-stage instrument before SAFEs gained popularity. They're still common because they're well-understood legally and provide some downside protection to investors.

Why it matters for founders

Convertible notes let you raise money quickly without negotiating a valuation when your company is hard to value. They defer the valuation discussion to a later round when there's more data. Understanding the terms prevents founders from giving away too much equity.

Example

A founder raises $250K on a convertible note with a $3M valuation cap and 20% discount. When they raise a $5M-valuation seed round, the note converts at the $3M cap (not $5M), giving the angel investor more shares. The cap protects the early investor's upside.
