Clear comparison of SAFEs and convertible notes for pre-seed and seed rounds, with when to use each.
SAFEs and convertible notes look similar and behave very differently at conversion. Picking the wrong one costs equity or triggers awkward investor conversations.
You're raising in the US, angels are comfortable with post-money SAFEs, and you want zero interest, no maturity, and standard YC docs.
Investors want debt features (interest, maturity), you're outside the US, or your lead insists. Notes carry real repayment obligation at maturity.
Stacking multiple post-money SAFEs at different caps dilutes founders more than they expect. Model conversion before signing the third one.
