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?

![Cap Table](https://s3.us-east-1.amazonaws.com/assets.plox.in/www/RsjjIzyhC1jHv63VrdrTvIEHPcM.png)

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

- Maintain Accuracy: Always match legal docs
- Update Regularly: Every grant or raise
- Plan for Dilution: Simulate round impacts
- Use Software: Avoid Excel errors
