Convertible Notes are debt instruments that convert into equity at a future date, typically upon the occurrence of a qualified financing round. They carry an interest rate and a maturity date, and often include a valuation cap and a discount.
SAFE Notes, on the other hand, are not debt instruments and do not accrue interest. They represent a right to future equity, converting into shares upon a future equity financing event. SAFEs are generally simpler and more streamlined than convertible notes.
Both instruments are popular in early-stage funding due to their ability to defer complex valuation negotiations, allowing founders to focus on building their business while securing necessary capital.
