Understanding Cap Tables: A Founder's Guide to Ownership
The essential guide to understanding cap tables, why they matter, and how to think about equity ownership at every stage of your company's growth.
Introduction
If you're a founder, investor, or early employee at a startup, there's one document you must understand deeply: the cap table.
Short for "capitalization table," your cap table tells the story of who owns what — and how that might change as your company grows. It's one of the most important (and misunderstood) tools in startup life.
Here's an overview of what a cap table is, why it matters, and how to think about it at every stage of your company.
What Is a Cap Table?
A cap table is a record of a company's equity ownership. It typically includes:
- Founders' shares
- Investor ownership from equity rounds or convertibles
- Employee stock option pool (ESOP)
- Outstanding SAFEs, notes, warrants, or other convertible securities
It shows who owns what — in both number of shares and percent of the company — and how that ownership will change after financing, hiring, or exits.
Why Cap Tables Matter
Cap tables are about more than numbers. They reflect the distribution of power, control, and economics in your company.
They affect:
Decision-making
Voting rights and board control
Fundraising
How much you give up in each round
Recruiting
What you can offer to future employees
Exits
Who gets what in an acquisition or IPO
If your cap table is unclear, messy, or misunderstood — it can blow up a deal or create founder friction down the road.
Key Concepts to Know
Fully Diluted Shares
This is the total number of shares outstanding if all options, SAFEs, notes, and warrants convert. This is the denominator investors care about.
Ownership vs. Value
Owning 10% of a startup worth $5M isn't the same as owning 10% of one worth $50M. The cap table tracks percentages, but value is always changing.
Pre-Money vs. Post-Money
- Pre-money valuation is the company's value before new investment.
- Post-money = pre-money + new investment.
Important when modeling dilution and pricing new rounds.
Option Pool
Shares reserved for employees and advisors. Usually 10–20%, often added before a funding round — which dilutes founders more than investors.
Cap Table Stages: How It Evolves
Early Stage (Friends & Founders)
- Founders split shares — ideally with vesting
- Option pool is created
- Maybe a few friends/family or angel SAFEs
Seed Round
- SAFEs/convertible notes start converting
- Institutional investors come in
- Option pool top-up often required
- Cap table starts getting complex
Series A+
- Priced rounds with negotiated ownership
- Multiple share classes (common vs. preferred)
- Protective provisions, board seats, liquidation preferences
- Dilution begins to snowball
Later Stages
- Multiple rounds, employee turnover, option refreshes
- Secondary sales and liquidity events
- Exit planning, waterfalls, and tax considerations
Common Mistakes
- ❌ No founder vesting
- ❌ Giving away too much equity early
- ❌ Not modeling dilution before raising
- ❌ Verbal promises not reflected on the cap table
- ❌ Not understanding convertibles and SAFEs
A bad cap table can scare off investors, block fundraising, or create costly surprises in M&A.
