Explain the Mechanics of a Cap Table to a First-Time Founder

Most founders sign their first funding documents only half understanding them. Tell it your company stage and how the equity is split, and it explains how a cap table works and what your situation actually means, so you can ask sharper questions before you sign. Good for a first-time founder heading into a raise.

**Explain a cap table and its implications for the situation below:**
Company stage: {COMPANY_STAGE}
Current equity distribution: [describe: founder shares, employee option pool, any existing investors]
Upcoming event: [first funding round / employee options / new co-founder / other]

**Cover in order:**
1. What a cap table is: who owns what percentage of the company, in plain English
2. How dilution works: what happens to each shareholder's percentage when new shares are issued
3. The option pool: what it is, why investors require it, and what it costs the founders
4. The pre-money vs post-money distinction: explained with a concrete example using simple numbers
5. The three questions every founder should ask before signing an investment term sheet related to equity

**Grounding rule:** use the stated structure to illustrate with simple numbers. Keep all examples in whole percentages to avoid false precision.
