# Cap Table Manager

Founders lose more value to cap-table mistakes they did not model than to
valuation they negotiated badly. This skill makes dilution legible: you should
be able to state what you own after the next two rounds, and why.

## When to use this skill

Use it during [[fundraising-stage-selector]] to pressure-test dilution, before
signing any SAFE or term sheet, and whenever someone says "we'll just expand the
pool." Pair instrument mechanics with [[safe-vs-priced-round]].

## The mechanics that actually move ownership

### Pre-money vs post-money
- Post-money valuation = pre-money + new investment.
- Investor ownership = investment ÷ post-money. ($2M into $8M pre => $10M post
  => 20% to investors.)
- Modern SAFEs (post-money SAFEs) lock the investor's percentage; founders
  dilute *around* them when later money comes in. Know which kind you signed.… install to load the full skill
