§Anatomy

What lives on a cap table

Common stock

Founders, early employees, advisors with non-preferred grants. Lower priority in liquidation than preferred.

Preferred stock

Investors. Each round typically a new series (Seed Preferred, Series A Preferred). Carries liquidation preference, anti-dilution, board rights.

Option pool

Reserved shares for employee grants. Tracked as authorised, granted, vested, and exercised. Unallocated pool is shadow ownership until granted.

Convertibles

SAFEs and convertible notes. Off the basic cap table until they convert at a priced round. Always model fully diluted including conversion.

§FAQ

Cap table FAQ

A cap table (capitalisation table) is a record of who owns what in a company. It lists every shareholder, their share class (common, preferred), their share count, their ownership percentage (both basic and fully diluted), and any convertible securities (SAFEs, notes, warrants). For startups, it is the single most important spreadsheet you maintain.
