A SAFE (Simple Agreement for Future Equity) is a 5-page investment instrument developed by Y Combinator in 2013 as an alternative to convertible notes. SAFEs aren't debt — no interest, no maturity date, no repayment obligation. They convert to equity at the next priced round, typically at a valuation cap, discount, or both. Faster and cheaper to execute than convertible notes. Founder-friendly but can stack confusingly — multiple SAFEs with different caps create complex conversion mechanics at Series A. Post-money SAFEs (introduced 2018) make dilution math more predictable. Standard for pre-seed and seed rounds, replacing convertible notes in much of the startup ecosystem.
