How SAFE Notes Impact Founder Dilution and Startup Equity

Kruze Consulting Free Intermediate

This is the worked walkthrough the question demands, not theory. It runs the exact scenario you fear: two SAFEs at different caps ($500K at $10M cap and $500K at $5M cap) converting at a $20M Series A, and shows the low-cap money buying twice the shares per dollar (1M shares vs 500K) so founders land ~3 points more diluted for the same money raised. It walks the conversion price math per SAFE, covers cap vs discount (investor takes whichever gives more shares), and hammers the point that the terms, not the dollars, are what dilute you. Free, no paywall, and specific enough to copy the numbers into your own model.

• A low-cap SAFE converts to more shares per dollar, so $500K at a $5M cap costs you far more equity than $500K at a $10M cap even though it is the same cash
• Each SAFE converts independently at its own cap or discount, whichever gives the investor more shares, so stacking compounds silently
• The dilution is set the day you sign, not at the priced round, which is why you model the whole stack before signing the next one
