SAFE
SAFE
Simple Agreement for Future Equity — a popular early-stage investment instrument that converts to equity at a later funding round.
Definition
A SAFE (Simple Agreement for Future Equity) is a contractual agreement between a startup and an investor in which the investor provides capital today in exchange for the right to receive equity in a future priced round. SAFEs were introduced by Y Combinator in 2013 to simplify early-stage fundraising. The two key terms are the valuation cap (maximum valuation at which the SAFE converts) and the discount rate (percentage reduction on the conversion price). SAFEs are not debt — they have no interest rate or maturity date.
Why It Matters
SAFEs are the dominant instrument for pre-seed and seed financing in Silicon Valley. They are fast (days vs. weeks for priced rounds), cheap (no lawyer fees for negotiating interest rates or maturities), and founder-friendly. Understanding your SAFE terms determines how much dilution you take at your next priced round.
Example
An investor puts in $200,000 on a $5M cap SAFE. At Series A with a $20M pre-money valuation, the SAFE converts as if the investor bought at $5M — giving them 4× more equity than a non-SAFE investor at the same round.
