A SAFE (Simple Agreement for Future Equity) is a financial instrument used in startup financing to provide a simple and quick way for investors to invest in a company in exchange for the right to receive equity in the future. A SAFE is a hybrid between a convertible debt instrument and a traditional equity instrument, in that it does not have a set maturity date, interest rate, or repayment terms like a convertible debt, but it provides the investor with the right to receive equity in the company, typically upon the occurrence of certain events, such as a future financing round or the sale of the company. The key feature of a SAFE is its simplicity, as it does not require the negotiation of complex terms and documentation as compared to a traditional equity financing round.
