What is a SAFE? A SAFE (Simple Agreement for Future Equity) is a startup financing instrument created by Y Combinator. Investors give money now in exchange for equity at the next priced round, at a discount or capped valuation. This calculator uses the post-money SAFE model (YC standard since 2018).
