How SAFEs Work

A SAFE (Simple Agreement for Future Equity) is an investment instrument that converts to equity during a future priced round. SAFEs were created by Y Combinator as a founder-friendly alternative to convertible notes.

Key Terms

  • Valuation Cap: The maximum valuation at which the SAFE converts. If the priced round is at a higher valuation, SAFE investors get the cap price.
  • Discount: A percentage reduction from the priced round price. Investors get the lower of the cap price or the discounted price.
  • Post-Money vs Pre-Money: Post-money SAFEs (now standard) give investors a fixed ownership percentage. Pre-money SAFEs calculate ownership based on the cap table at conversion.
