A Cap Table (capitalization table) records company equity ownership — listing all shareholders, their shares, percentages, and equity types. It's central to funding, M&A, and IPO decisions.

How is dilution calculated?

After a new round: Old ownership = Previous % × (1 - New investor %). E.g., founder at 80%, new investor takes 20%, founder dilutes to 80% × 80% = 64%. This tool auto-calculates per-round dilution.

What is an option pool?

An option pool is shares reserved for employee equity grants, typically created before funding rounds. It dilutes existing shareholders. Common sizes: 10-20%.

How do SAFEs and convertible notes affect equity?

SAFEs and convertible notes are deferred-pricing instruments. They convert at a discount or valuation cap. This tool supports discount rates and caps to simulate post-conversion ownership.

How to avoid excessive dilution?

1) Raise at fair valuations; 2) Limit per-round dilution to 10-25%; 3) Plan option pools ahead; 4) Use SAFEs/notes to defer pricing; 5) Grow to higher valuations before raising.
