What Is a Cap Table? A Complete Guide for Founders

A cap table — short for capitalisation table — is a document that details a company's equity ownership structure, listing all shareholders, the types and number of securities they hold, and their ownership percentages.

Why Cap Tables Matter

An accurate, up-to-date cap table is essential for making informed financial and hiring decisions, conducting due diligence with investors, calculating dilution, and planning future fundraising rounds. Investors will request a cap table during due diligence — a messy or inaccurate one can delay or kill a deal.

Key Components of a Cap Table

• Shareholders: Founders, investors, employees with equity
• Share Classes: Common stock, preferred stock, options, warrants
• Total Shares and Ownership Percentages: Who owns how much
• Unissued Shares: Allocated but not yet distributed
• Option Pool: Shares reserved for employee equity incentives
• Convertible Instruments: SAFEs, convertible notes, warrants that may convert to equity

How Cap Tables Evolve

A cap table starts simple — typically just the founders' shares. It grows more complex with each funding round, employee option grant, and share transfer. After a Series A, the cap table might include:

• Founders' common shares
• Seed investor preferred shares
• SAFE holders who converted
• Employee option pool
• Advisor shares

Cap Table Management Best Practices

• Keep the cap table accurate and up-to-date after every equity event
• Use cap table software rather than spreadsheets for complex structures
• Plan for dilution before each funding round
• Ensure legal compliance with share issuance rules
