Why cap table matters to a first-time founder
Investors, lawyers and future hires all rely on the cap table to know what they are buying into. If it is wrong or out of date, every funding conversation starts with an argument about the past, legal costs rise and a round can stall while the record is fixed. A clean one also lets you model how much each founder will own after the next raise before you agree to it.
Examples of cap table
Before a round, two founders hold 45% each and the option pool represents 10% on a fully diluted basis. If an angel buys 20% post-money, the model shows 36% for each founder, 8% for the pool, and 20% for the angel. The same cap table shows the position before and after the deal.
Common misunderstanding
People treat the cap table as paperwork they will tidy up later, or they confuse it with a term sheet. A term sheet proposes a deal. The cap table is the ownership that already exists, including every promise of shares you have already made.
When to use it
Start a cap table on the day a second person has a claim on the company, including a promise of shares in the future. Update it before you negotiate, not afterwards. If you cannot say who owns what this afternoon, sort that out before you discuss terms.
