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 - **New option pool** target, and whether it's pre- or post-money ("the pool shuffle") ## Output Format ### 1. Plain-English summary What this round does to ownership, in 3 sentences. ### 2. Ownership before → after | Holder | Shares / % before |

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
