Post-money SAFE
Quick definition
YC's 2018 SAFE form that locks in the investor's ownership percentage post-conversion regardless of subsequent SAFE stacking.
A post-money SAFE applies its valuation cap to the company's post-money valuation, fixing the SAFE holder's percentage at conversion. The advantage for the investor: their ownership doesn't dilute if more SAFEs are issued before the priced round. The disadvantage for founders: stacking multiple post-money SAFEs causes founder dilution that's not immediately obvious. Always model post-money SAFE dilution before signing.
