    SAFE

    Also called: Simple Agreement for Future Equity

    TL;DR

    Y Combinator's Simple Agreement for Future Equity, a contract that gives an investor the right to equity in a future priced round, with no debt or interest.

    A SAFE is a contract created by Y Combinator in 2013 to standardize early-stage investing. Unlike a convertible note, a SAFE is not debt: there's no interest, no maturity date, and no repayment if the company fails. It converts into equity at the next priced round, usually at a discount, a valuation cap, or both.

    SAFEs come in pre-money and post-money flavors; the post-money SAFE introduced in 2018 is now standard at YC. SAFEs are popular because they close fast (a few hours of legal work) and avoid the complexity of negotiating a priced round at the earliest stage.

    Worked example

    A team raises $1M on a post-money SAFE with a $10M cap. If the next priced round closes at a $40M pre-money valuation, the SAFE converts at the $10M cap → SAFE holder owns $1M ÷ $10M = 10% post-money on the SAFE round.

    Common pitfalls

    • Stacking many SAFEs at different caps without modeling dilution.
    • Confusing pre-money and post-money SAFE math.
    • Treating the cap as the price, it's a ceiling, not a guarantee.

    When this shows up in a pitch deck

    SAFE structure shows up implicitly in cap-table modeling but rarely in deck copy itself. Deckmetric's YC framework page links to SAFE conversion mechanics.
