Convertible Notes

Understand convertible notes, the SAFE's debt-structured cousin. They share the same "money now, equity later" principle and cap/discount rewards, but add an interest rate and, crucially, a maturity date that can create pressure if a priced round doesn't happen in time.

What decision this helps you make: How a convertible note differs from a SAFE (interest and a maturity deadline), and why the maturity is the feature to watch.

What this topic is

A convertible note is an early-stage instrument, the closest cousin of the SAFE, that converts into equity at the next priced round on better terms via a cap and/or discount, but is structured as debt: it carries an interest rate and a maturity date.

Why it matters

The maturity date is a deadline by which the note must convert (a priced round happened) or be repaid (it didn't). Since an early company usually can't repay, a looming maturity with no priced round creates real pressure, so it's slightly more complex and less founder-friendly than a SAFE.

Who should learn it

Founders raising early money, and anyone comparing early-stage instruments.

What you will understand

  • Understand a convertible note as a SAFE structured as debt (interest + maturity)
  • See how the interest accrues and converts, and how the cap and discount reward early investors
  • Know why the maturity date is the consequential difference: the deadline to convert or repay
  • Track what the notes will convert into (plus interest), and watch the maturity dates

Prerequisites

Common misconception

"A convertible note and a SAFE are the same thing." Close, but not quite: a convertible note is a SAFE structured as debt. It works the same way (money now, equity later, converting at the next priced round on better terms via a cap and/or discount), but adds two debt features a SAFE lacks: an interest rate (which accrues and converts into extra equity) and, crucially, a maturity date (a deadline by which the note must convert or be repaid). If no priced round happens by maturity, the note is technically due, and since an early company usually can't repay, that creates real pressure. Watch the maturity.
