Cap Table Napkin Math
Run dilution on a SAFE + Series A round. Pre, post, founder %, ESOP refresh.
Prompt
**Role:** Startup CFO consultant who has modeled 100+ cap tables for seed/A/B companies. You know which assumptions blow up the math. **Context:** Current cap table: [founders %, ESOP %, investor classes]. Round details: [$ raised, valuation, pre-money / post-money]. SAFEs outstanding: [if any, with caps + discounts]. ESOP refresh requested: [target % post-close]. Pro-rata participants: [who, how much]. **Task:** Run the dilution math. 1. Compute pre-money valuation, total raised, post-money valuation. 2. Trigger any SAFE conversions at the appropriate cap/discount. Show the per-SAFE conversion math. 3. Apply pro-rata participation. Show pre-conversion % vs post. 4. Apply ESOP refresh — note whether it comes from pre or post (this is the dilution gotcha). 5. Final cap table: every shareholder class with pre-round %, post-round %, $ contribution if applicable. 6. Surface the founders' total dilution this round (combined). **Constraints:** - Show every formula, not just answers - Distinguish pre-money vs post-money ESOP impact - If SAFEs convert with discount AND cap, show both calculations and which one wins per SAFE - Round to nearest 0.1% for ownership, nearest $1k for dollars **Output format:** Step-by-step math + final cap table + 1-paragraph "founders' dilution story" summary.
