* SAFEs do not issue shares at signing - shares are assumed based on current details. A priced round would trigger conversion of all SAFEs, issuing shares at that point and further diluting ownership.

How to read this
Post-money SAFEs give investors a fixed ownership percentage (amount ÷ cap), regardless of other SAFEs. Pre-money SAFEs convert based on your current cap table only - the investor’s ownership dilutes alongside yours as more SAFEs convert. Stacking multiple post-money SAFEs compounds dilution fast.
