cap-table-explainer
Explain a cap table, dilution, SAFEs, option pools, and round mechanics in plain English with the actual math. Use when asked to explain dilution, model a SAFE or priced round, size an option pool, understand a term sheet's economics, or figure out who owns what after a raise. Produces a worked ownership breakdown before/after the round, the dilution math step by step, and the traps founders miss. Not legal or financial advice.

# Cap Table Explainer Skill
Dilution math quietly decides how much of your company you keep. This skill walks through it with real numbers — pre/post-money, SAFEs, option pools, and conversions — so the founder sees exactly who owns what and why. **Not legal or financial advice; confirm with counsel before signing.**
## Working from a brief
Given partial terms, **work the full example anyway** with the numbers provided, and clearly state every assumption (e.g. *assumed $1M pre-existing on a $X pre-money*). If numbers are missing, pick clean illustrative ones and label them. Never leave the math as "[calculate]".
## Required Inputs
Ask for (if not already provided), else use labelled illustrative figures:
- **Current ownership** (founders %, existing investors, current option pool)
- **The round**: amount raised, pre- or post-money valuation, instrument (priced equity, SAFE, convertible note)
- **SAFE/note terms** if any: cap, discount, MFN
