Why does Cap Table matter?
It is the single source of truth every fundraising, hiring, and exit decision runs through, and an inaccurate or stale one costs real money to fix at the worst possible time, usually mid-diligence on a round, when a buyer's lawyers find a discrepancy the founder cannot explain. Getting it wrong is not cosmetic: a cap table with unrecorded verbal promises, expired option grants still shown as outstanding, or SAFEs whose conversion terms were never modeled will surface as a fight over who owns what exactly when the company can least afford the delay.
What does Cap Table look like in practice?
Suppose a founder has been tracking equity commitments in a spreadsheet that was never updated after an advisor's grant was finalized or after two SAFEs were converted at the seed round. When Series A diligence begins, the lead investor's counsel reconstructs the actual cap table from signed documents and finds it does not match the spreadsheet the founder has been using to calculate their own ownership, the resulting reconciliation, and the trust cost of the mismatch, both land in the middle of closing the round.
What are the common mistakes with Cap Table?
- Maintaining the cap table in a spreadsheet that is not updated the moment each instrument is signed, rather than treating it as a live legal record.
- Forgetting to model SAFE and note conversions before a priced round, so the founders learn their post-round ownership for the first time during the round itself.
- Not distinguishing fully diluted ownership (including the option pool and all convertible securities) from currently issued ownership, investors evaluate the fully diluted number, and quoting the wrong one erodes credibility.
- Granting advisor or informal equity verbally and never papering it, leaving a gap between what people believe they own and what the legal documents say.

- DilutionThe reduction in each existing shareholder's percentage ownership that happens whenever a company issues new shares, whether from a new financing round or a new option pool.
- SAFEs and Convertible NotesTwo instruments that let an investor put money in now and receive equity later, at a price set when a future priced round happens, instead of negotiating a valuation today.
- Employee Stock Option Pool (ESOP)A block of equity set aside, and typically expanded before each priced financing round, to grant stock options to current and future employees without renegotiating ownership every time someone is hired.
- Vesting and the CliffVesting is earning equity gradually over time by staying with the company; the cliff is the initial period, usually one year, during which none of it vests, so someone who leaves early walks away with nothing.
