Frequently asked questions
How does a SAFE convert to equity?
A SAFE (Simple Agreement for Future Equity) converts into shares at the next priced equity round. The conversion price is the lower of the valuation-cap price and the discounted round price, giving early investors a better deal for their risk.
What is a valuation cap?
A cap is the maximum company valuation at which a SAFE converts. If the priced round is above the cap, the investor converts as if the company were valued at the cap — earning them more shares per dollar.
What is a SAFE discount?
A discount (commonly 10–20%) lets the SAFE holder convert at a percentage below the priced round's share price. If both a cap and a discount exist, the investor gets whichever produces the lower price (more shares).
Does this model post-money or pre-money SAFEs?
This is a simplified pre-money-style model for understanding mechanics. Real post-money SAFEs (the current YC standard) fix the investor's ownership percentage and have different dilution math — always confirm exact terms with your lawyer.
