How to Build a Startup Cap Table: A Founder’s Guide
Startup Operations · Founder's Guide
A cap table is one of the most important financial and ownership records a startup can maintain. It shows who owns the company, how much they own, and what securities or rights may affect ownership in the future. This guide explains what a startup cap table is, what it should contain, how to build one, and how it changes during fundraising.
A cap table, short for capitalization table, is one of the most important financial and ownership records a startup can maintain. It shows who owns the company, how much they own, and what securities or rights may affect ownership in the future.
For founders, the cap table becomes increasingly important as the company hires employees, raises capital, issues SAFEs or convertible notes, creates an option pool, and completes additional financing rounds. A clean cap table helps founders understand dilution, negotiate financing, and make informed decisions about ownership.
What Is a Startup Cap Table?
A capitalization table is a record of a company's ownership and relevant securities. A basic cap table may show:
Founders
Investors
Employees
Share classes
Number of shares
Ownership percentages
Options
Warrants
Convertible securities
Other equity interests
The cap table provides a snapshot of the company's capitalization at a particular point in time.
CODEW Lens: A cap table is not a spreadsheet. It is a strategic map. The founders who treat it as an operating document — not a filing requirement — are the ones who negotiate from strength.
Why Is a Cap Table Important?
A cap table answers fundamental questions: Who owns the company? How much does each person own? How much equity has been reserved for employees? How much dilution will occur in a new financing? Who has preferred stock? What happens if outstanding SAFEs or notes convert?
Without an accurate cap table, founders can make expensive financing decisions without understanding their actual ownership.
CODEW Lens: You cannot negotiate what you cannot see. The cap table is the instrument that makes ownership visible — and visible ownership is negotiable ownership.
A Simple Example
Imagine a startup initially issues:
Founder A: 500,000 shares
Founder B: 300,000 shares
Employee pool: 200,000 shares
Total: 1,000,000 shares
Ownership:
Founder A: 50%
Founder B: 30%
Employee pool: 20%
This is a simplified example. Actual startup capitalization can become considerably more complex once investors and convertible securities are introduced.
CODEW Lens: Simple cap tables are easy. Simple cap tables that stay simple as you scale are rare. The discipline starts at formation.
What Should a Cap Table Include?
A cap table can include several categories:
Shareholders — The people or entities that directly own shares.
Share Classes — Different classes of stock, such as common and preferred stock.
Options — Shares that may be issued to employees or other eligible participants under an equity incentive plan.
Convertible Securities — Instruments such as SAFEs and convertible notes that may convert into equity.
Warrants — Rights to purchase shares under specified conditions.
Ownership Percentage — Each holder's percentage ownership based on the applicable capitalization calculation.
Common Stock vs. Preferred Stock
A startup may have multiple classes of shares.
Common Stock — Commonly held by founders and employees.
Preferred Stock — Institutional investors frequently receive preferred stock with additional contractual rights.
These rights can include:
Liquidation preferences
Voting rights
Conversion rights
Anti-dilution provisions
Pro rata rights
The cap table should distinguish between relevant security classes.
CODEW Lens: Preferred stock is not just a different share class. It is a different set of economic and governance rights. The cap table must show both.
Founder Ownership
At formation, founders typically hold most or all of the company's equity. Suppose:
Founder A: 600,000 shares
Founder B: 400,000 shares
Total: 1,000,000 shares
Ownership:
Founder A: 60%
Founder B: 40%
This establishes the initial capitalization before future equity issuance.
CODEW Lens: Founder splits are not math problems. They are relationship decisions with mathematical consequences. Document them clearly before you need to defend them.
Founder Equity Splits
Founders should document how ownership is divided. The split can reflect factors such as:
Contributions
Roles
Responsibilities
Time commitment
Intellectual property
Previous work
Future responsibilities
There is no universal formula for splitting founder equity. The important point is to agree clearly and document the arrangement.
Founder Vesting
Founder shares may be subject to vesting. A common structure uses a multi-year vesting period with an initial cliff, although actual terms vary.
Vesting is designed to ensure that founders earn or retain their equity over time rather than immediately owning all of it without conditions. The exact legal and economic terms should be reviewed with qualified counsel.
CODEW Lens: Vesting is not about distrust. It is about alignment. The founder who stays earns the equity. The founder who leaves does not take it with them.
Employee Option Pool
Startups frequently establish an employee option pool. This reserves equity for future employees and other eligible participants. For example:
Founders: 80%
Employee option pool: 20%
The option pool can help startups recruit employees by offering equity-based compensation.
CODEW Lens: The option pool is not a cost center. It is the currency you use to buy talent when you cannot pay market salaries.
Why the Option Pool Matters During Fundraising
The option pool can have a significant impact on founder dilution. An investor may negotiate for an option pool to be created or increased before the financing. This matters because the economic impact can fall disproportionately on existing shareholders depending on how the transaction is structured.
Founders should model the cap table carefully before agreeing to an option-pool adjustment.
CODEW Lens: The option pool increase is often the most expensive line item in a term sheet that nobody talks about.
Pre-Money vs. Post-Money Ownership
Suppose a startup has an $8 million pre-money valuation and raises $2 million. The simplified post-money valuation is $10 million. The new investor's simplified ownership is 20%. Existing shareholders collectively own 80%.
The actual calculation may differ depending on the company's capitalization and financing terms.
CODEW Lens: Pre-money is the price. Post-money is the outcome. Negotiate the price knowing you are buying the outcome.
Cap Table After a Financing
Before financing:
| Founder A | 50% |
| Founder B | 30% |
| Employee Pool | 20% |
| Total | 100% |
After a simplified financing where a new investor receives 20%:
| Founder A | 40% |
| Founder B | 24% |
| Employee Pool | 16% |
| New Investor | 20% |
| Total | 100% |
The founders' percentages decline because new equity has been issued. This is dilution.
What Is Dilution?
Dilution occurs when new shares or equity-linked securities are issued, and an existing shareholder's percentage ownership decreases. Dilution does not necessarily mean the value of an investment has decreased.
A founder owns: 50% of a $10 million company
The founder's stake is economically worth approximately: $5 million
If the founder is diluted to: 40% of a $20 million company
The stake could be worth: $8 million
The ownership percentage decreased. The potential value of the ownership increased. This is why founders should evaluate both percentage ownership and company value.
CODEW Lens: Dilution is not failure. It is the price of building a bigger pie. A 20% dilution that triples the company's value is a good trade.
SAFEs and the Cap Table
A SAFE can complicate capitalization because it represents a contractual right to receive equity under specified conditions. Depending on the SAFE's terms, conversion may be affected by:
Valuation cap
Discount
Financing structure
Post-money or pre-money treatment
Other contractual provisions
Founders should model outstanding SAFEs before entering a priced financing.
CODEW Lens: A SAFE is not debt. It has no interest, no maturity, and no repayment obligation. But it is also not free equity — it defers dilution to a moment when the founder may have less leverage to negotiate it.
Convertible Notes and the Cap Table
Convertible notes are debt instruments that can convert into equity under specified conditions. The eventual number of shares issued can depend on:
Principal
Accrued interest
Conversion price
Discount
Valuation cap
Qualified financing
Maturity provisions
Outstanding notes should therefore be included in capitalization planning even before they convert.
CODEW Lens: Convertible notes are debt pretending to be equity. Model them as both, or you will be surprised by both.
Fully Diluted Ownership
A fully diluted cap table attempts to account for relevant securities that could result in additional shares. This may include:
Common shares
Preferred shares
Options
Warrants
Convertible securities
Other potentially issuable equity
The exact definition of fully diluted capitalization can vary by transaction and legal documents. Always understand what securities are included in the calculation being used.
Authorized vs. Issued Shares
Authorized Shares — The number of shares the company is legally permitted to issue under its governing documents.
Issued Shares — Shares that have actually been issued to shareholders.
A company can have more authorized shares than currently issued shares. The difference provides potential flexibility for future issuance.
Outstanding Shares
Outstanding shares generally refer to shares that have been issued and remain outstanding. This is different from authorized shares and can also differ from fully diluted capitalization.
Terminology varies across jurisdictions and transaction documents, so founders should use the definitions applicable to their company's legal structure.
Primary Financing
In a primary financing, the company issues new securities and receives the investment proceeds. Example: An investor invests $3 million. The company issues new shares. The $3 million goes to the company. The cap table changes because new shares are issued.
Secondary Sale
In a secondary transaction, an existing shareholder sells shares. Example: A founder sells 100,000 shares to an investor. The company generally does not receive the purchase proceeds. Ownership transfers from one shareholder to another.
A secondary transaction therefore differs fundamentally from a primary financing.
CODEW Lens: Primary financing funds the company. Secondary sale funds the shareholder. Do not confuse the two.
Modeling a New Financing
Before accepting a financing, founders should create a pro forma cap table. It should show:
Current capitalization
New securities
Option-pool changes
Conversion of existing securities
= Post-financing capitalization
This helps founders understand exactly what ownership will look like after closing.
CODEW Lens: Model before you negotiate. The founders who know the answer before the term sheet arrives are the ones who shape the term sheet.
Cap Table Waterfall
A waterfall can be used to model how proceeds from an exit are distributed among shareholders and securities. It can account for:
Common stock
Preferred stock
Liquidation preferences
Participation rights
Conversion
Other contractual provisions
This becomes particularly important when different investors have different economic rights.
Liquidation Preferences and the Cap Table
Ownership percentage alone does not always tell the complete economic story. Two investors can own similar percentages but have different economic rights. For example, one investor may hold preferred stock with a liquidation preference while another holds common stock.
Therefore, founders should analyze both ownership and economic rights.
CODEW Lens: Two shareholders can own the same percentage and be entitled to wildly different outcomes. The cap table shows the percentage. The waterfall shows the dollars.
Board Seats vs. Ownership
A cap table shows ownership. It does not necessarily tell you everything about corporate control. Control can also be affected by:
Board composition
Voting rights
Protective provisions
Investor agreements
Shareholder agreements
A founder can retain a significant economic stake while having different levels of governance control depending on the company's legal structure.
CODEW Lens: Ownership is economic. Control is structural. Founders who confuse the two are the ones who get surprised at the board meeting.
How the Cap Table Changes Over Time
A startup's capitalization evolves. A simplified lifecycle may look like:
Founders → Employee option pool → SAFE/convertible financing → Seed round → Series A → Series B → Later rounds → Exit
Every new financing can change ownership.
CODEW Lens: The cap table is a living document. Treat it like one, or it will treat you like a stranger at the worst possible moment.
Cap Table Scenario Planning
Founders should model multiple scenarios. For example:
Scenario A — Raise $2 million at an $8 million pre-money valuation.
Scenario B — Raise $3 million at a $10 million pre-money valuation.
Scenario C — Raise $5 million at a $15 million pre-money valuation.
Compare:
Founder ownership
Investor ownership
Option pool
Fully diluted ownership
Future dilution
This can help founders understand the trade-offs before negotiations.
The Importance of Modeling Future Rounds
A financing that looks attractive today may create difficult consequences later. Suppose founders raise a large amount at an early stage. If the company later struggles to grow into that valuation, the next financing could become difficult.
Potential consequences can include:
Down rounds
Greater dilution
Additional investor protections
Reduced founder ownership
The cap table should therefore be considered as part of the company's long-term financing strategy.
CODEW Lens: Today's round is tomorrow's baseline. Model three rounds ahead, not one.
Common Cap Table Mistakes
Keeping the Cap Table in a Simple Spreadsheet Forever — Spreadsheets can work at very early stages but become harder to manage as capitalization becomes complex.
Forgetting SAFEs — Outstanding SAFEs can materially affect future ownership.
Ignoring Convertible Notes — Notes may convert during a financing and change the capitalization.
Misunderstanding the Option Pool — The timing and size of an option-pool increase can materially affect dilution.
Mixing Primary and Secondary Shares — These transactions have different economic effects.
Ignoring Preferred Rights — Ownership percentages do not capture every economic right.
Not Modeling Future Financing — Founders should understand how today's deal affects tomorrow's ownership.
Failing to Update the Cap Table — Every relevant equity transaction should be properly recorded.
CODEW Lens: Most cap table mistakes are not math errors. They are documentation errors. The spreadsheet is fine. The process is broken.
Cap Table Due Diligence
Investors will typically want confidence that the company's capitalization is accurate. They may examine:
Founder ownership
Share issuances
Option grants
SAFE agreements
Convertible notes
Warrants
Previous financing documents
Board approvals
Shareholder agreements
Inconsistencies can slow or complicate fundraising.
What Founders Should Keep Organized
Maintain copies of relevant:
Incorporation documents
Share issuance records
Stock purchase agreements
Option plans
Option grants
SAFE agreements
Convertible notes
Financing documents
Board approvals
Shareholder agreements
The exact documents depend on the company's jurisdiction and structure.
Cap Table Checklist
Before a major financing, verify:
Founder ownership is correct.
All shareholders are recorded.
Share counts are accurate.
Share classes are identified.
Options are included.
Outstanding SAFEs are recorded.
Convertible notes are recorded.
Warrants are recorded.
Option pool is accurate.
Fully diluted ownership is understood.
New financing has been modeled.
Dilution has been calculated.
Investor rights are understood.
Corporate records match the cap table.
Cap Table Questions Every Founder Should Be Able to Answer
You should know:
How many shares are outstanding?
Who owns them?
What percentage does each founder own?
How large is the employee option pool?
How many options have been granted?
How many SAFEs are outstanding?
How many convertible notes are outstanding?
What happens if they convert?
What will ownership look like after the next financing?
What happens under different valuation scenarios?
If you cannot answer these questions, your capitalization model probably needs attention.
CODEW Lens: If you cannot answer these questions in a board meeting without looking at a spreadsheet, you do not own your cap table. Your cap table owns you.
The Bottom Line
A cap table is more than an ownership spreadsheet. It is a strategic map of the company's capitalization. It helps founders understand:
Ownership
Dilution
Investor economics
Employee equity
Financing consequences
Potential exit outcomes
As a startup grows, the cap table becomes increasingly important. Before raising capital, founders should model the transaction carefully and understand exactly how the financing affects ownership.
Never negotiate a financing without understanding the cap table behind it.
CODEW Lens: The cap table is the instrument of ownership. Master it early, or it will master you later.

FAQ
Q: When should a founder start building a cap table?
At formation. The moment founders agree on an equity split, the cap table exists — whether it is documented or not. Starting early with a clean structure makes every future financing, hire, and exit easier. A cap table that starts clean stays clean longer.
Q: Can I use a spreadsheet for my cap table?
Yes — at the earliest stages. Spreadsheets work fine when the company has only founders and a simple option pool. They become harder to manage once SAFEs, convertible notes, multiple share classes, and repeated financings are introduced. Many startups migrate to dedicated cap table software before a Series A.
Q: How do SAFEs affect the cap table?
SAFEs are not shares. They are contractual rights to receive equity under specified conditions. They do not appear as ownership on the cap table until they convert — typically during a priced financing. But they must be modeled before that financing, because their conversion will dilute existing shareholders. Founders who ignore outstanding SAFEs are often surprised by the dilution they create.
Q: What is the difference between authorized and issued shares?
Authorized shares are the maximum number of shares the company can legally issue under its governing documents. Issued shares are the ones that have actually been issued to shareholders. A company typically authorizes more shares than it has issued, giving it flexibility to issue new shares for hires, financings, or option grants without amending its charter.
Q: How often should I update my cap table?
Every time a relevant equity transaction occurs — a new hire receives options, a SAFE is signed, a convertible note is issued, a financing closes, or shares are transferred. The cap table should be a living document, not a quarterly exercise. Founders who update irregularly are the ones who discover inconsistencies during due diligence.
The CODEW Stat
80% founders · 20% option pool · 12 months A typical early-stage cap table leaves 80% for founders and 20% for an employee option pool. A $2M raise at an $8M pre-money valuation gives the new investor 20% and dilutes existing holders proportionally. And a founder who owns 50% of a $10M company and is diluted to 40% of a $20M company sees their stake go from $5M to $8M. The percentage goes down. The value goes up. The cap table is not a scoreboard. It is a strategy document.
