How to Use This Tool

Build your cap table by adding founders, investors, and option pools. Adjust ownership percentages and see how the full capitalization structure looks at each stage. This tool helps you visualize the complete picture of who owns what.

Why This Matters

Your cap table is the single source of truth for ownership in your company. Getting it wrong leads to legal disputes, tax problems, and unhappy investors. Every founder should be able to read and model their cap table — not just their lawyer.

The option pool trap

When a VC asks you to create a 15% option pool as part of a new round, that pool comes out of the pre-money valuation — meaning it dilutes existing shareholders (you) before the new investor buys in. On a $10,000,000 pre-money deal with a 15% pool, the effective pre-money to the founders is closer to $8,500,000. Always negotiate option pool size carefully.

What to Do With Your Results

  1. 1Model your next round — add a hypothetical Series A to see how your cap table evolves.
  2. 2Check your option pool — make sure you have enough equity reserved for future hires.
  3. 3Run exit scenarios — see what each stakeholder receives at different acquisition prices.
