What Is a Cap Table?
A cap table (capitalization table) is a document — usually a spreadsheet or specialized software — that shows the complete equity ownership structure of a company. It lists every shareholder, the type and number of shares they hold, and their percentage ownership of the company.
For startups, the cap table is one of the most important financial documents. It tells the story of who invested, how much they paid, what rights they have, and how ownership changes with each funding round.
Why Cap Tables Matter
For Fundraising
Every investor will ask to see your cap table during due diligence. A clean, well-organized cap table signals that your company is well-managed. A messy one is a red flag that can delay or kill a deal.
For Employee Compensation
Stock options are a major part of startup compensation. The cap table shows how much of the company is allocated to the employee option pool and what each person's shares are worth.
For Exit Planning
When your company is acquired or goes public, the cap table determines who gets paid, how much, and in what order. Liquidation preferences, participation rights, and conversion ratios all come from the cap table.
What's Included in a Cap Table
- Shareholder names: Every person or entity that owns equity
- Share classes: Common stock, preferred stock (Series Seed, A, B, etc.)
- Number of shares: How many shares each holder owns
- Ownership percentage: Both basic and fully diluted
- Share price: What was paid per share in each round
- Option pool: Reserved shares for employee stock options
- Convertible instruments: SAFEs, convertible notes, and warrants
- Vesting schedules: How shares vest over time
- Special rights: Liquidation preferences, anti-dilution provisions, pro-rata rights
How a Cap Table Changes Through Rounds
At Founding
A typical founding cap table is simple: two co-founders splitting equity, perhaps with a small advisor allocation. Most startups authorize 10 million shares and divide them among founders.
After Seed Round
The company issues new shares to seed investors (usually through SAFEs or preferred stock), creates an employee option pool (typically 10-15%), and founders get diluted proportionally.
After Series A
Lead investors negotiate preferred stock terms including liquidation preferences and board seats. The option pool is usually refreshed to 15-20%. Founders typically own 50-65% at this point.
After Series B and Beyond
Each subsequent round adds more investors, more dilution, and more complexity. By Series B, many cap tables include 5-10+ shareholders with different share classes and rights.
Cap Table Best Practices
- Start clean: Set up your cap table properly from day one with a clear founder equity split
- Keep it updated: Update after every equity event — funding rounds, option grants, exercises, and transfers
- Use proper tools: Graduate from spreadsheets to cap table software (Carta, Pulley, AngelList) as soon as you raise your seed round
- Track fully diluted: Always know your fully diluted ownership, not just basic shares outstanding
- Model future rounds: Use your cap table to model how future fundraising will affect ownership
- Maintain a clean data room: Keep all equity documents (SAFEs, stock purchase agreements, option grants) organized and accessible
Common Cap Table Mistakes
- Too many small investors: Having 50+ angels with tiny stakes creates legal and administrative headaches
- No vesting: Founders who don't vest their shares risk a co-founder leaving early with a large equity stake
- Not tracking convertible instruments: SAFEs and convertible notes that aren't properly modeled lead to surprises at conversion
- Giving away too much too early: Giving 10% to an advisor who contributes minimally is a costly mistake that compounds with each round
- Ignoring fully diluted math: Looking only at "on paper" ownership without counting options, warrants, and convertibles
