What are Cap Tables? A Complete Guide for Startups

If you're a founder heading into your first round, or an investor sizing up who owns what, the same document keeps showing up: the cap table.

This live blog covers what a cap table is, why it matters, how to build one from scratch, and how to keep it clean.

What is a Cap Table?

It details:

• Shareholders
• Number and type of shares
• Equity percentages
• Convertible instruments (SAFEs, Notes)
• Option pools
• Valuation events

Why it matters:

• You need it during fundraising and due diligence
• Tracks dilution across funding rounds
• Used for modeling exits or IPO scenarios

Structure of a Cap Table

Think of the cap table as a spreadsheet that moves with the company.

At the Seed stage, it's a short list:

• Founders and their shares
• Pre-seed investors
• Equity pool (optional)

By Series A, it includes:

• Preferred shares (Series Seed, A)
• Convertible instruments converted
• Option grants and exercises
• Price per share and valuation history

As the company grows, the document starts carrying real weight for:

• Strategic planning
• Stakeholder transparency
• Regulatory compliance

Key Components of a Cap Table

Most cap tables include the following.

1. Ownership Details

• Names of all shareholders
• Number of shares
• Equity percentages
• Roles (Founder, Investor, Employee, Advisor)

2. Types of Securities

• Common stock – Founders, early employees
• Preferred stock – Investors with privileges
• Stock options – For employees and advisors
• Warrants – Promised shares to external parties
• SAFEs / Notes – Convert to equity in future rounds

3. Share Classes

• Example: Class A Common, Series Seed Preferred
• Each has different rights (e.g. voting, liquidation)

4. Transaction History

• All funding events
• Option grants & exercises
• Share transfers
• Secondary sales

5. Valuation & Price Data

• Pre/post-money valuation
• Price per share (e.g., $1.50 Series A)
• 409A valuation for stock options

6. Dilution Modeling

• Forecasts dilution across future rounds
• Drives founder and investor negotiations

7. Exit Scenarios

• Shows payouts under M&A, IPO, or liquidation
• Matters most for preferred shareholders

Common Formats of Cap Tables

• Spreadsheet (Excel/Google Sheets): Best for early stages. Lightweight, manual.
• Cap Table Software (Carta, Pulley, Plox): Automates grants, tracking, dilution modeling, and compliance.

Plox has cap table tools built into your investor data rooms, so investors can see who owns what without leaving the platform.

How to Create a Cap Table

1. Start With the Basics

Collect:

• Authorized shares (e.g. 10M)
• Issued shares
• Shareholder details
• SAFEs or Notes (if any)

2. Add Founders’ Equity

E.g.

Founder	Shares	Ownership	Vesting
Alice	4M	40%	4 yrs
Bob	4M	40%	4 yrs

3. Add Investors

Track by:

• Round (e.g. Pre-Seed, Seed, Series A)
• Share class (e.g. Series A Preferred)
• Total shares and price paid

4. Add Option Pool

Typically 10–20% reserved. Track:

• Granted vs ungranted
• Vesting schedules

Cap Table Example

A simplified version, post-Seed round:

Shareholder	Shares	Class	Ownership
Alice (Founder)	4,000,000	Common	40%
Bob (Founder)	4,000,000	Common	40%
Investors	1,500,000	Series Seed Pref	15%
Option Pool	500,000	N/A	5%

Total: 10,000,000 shares

Cap Table Management Best Practices

• Update Regularly: Every grant or raise
• Plan for Dilution: Simulate round impacts
