What Is a Cap Table and How Equity Gets Divided in Startups

What Is a Cap Table?

A capitalization table (cap table) is a spreadsheet or formal document that shows the full equity ownership structure of a company — who owns how many shares, in what form, and at what price they were issued. It is the definitive legal record of ownership in a startup and one of the most important financial documents a company maintains. Cap tables are reviewed by investors during due diligence before every funding round, by acquirers evaluating a potential acquisition, and by founders and employees trying to understand the value of their equity.

At founding, a cap table is simple: it might show just the two co-founders each owning 50% of 10 million shares. Over time, as the company raises money from investors, issues options to employees, and makes other equity decisions, the cap table grows in complexity. By the time a startup is several years old and has raised multiple rounds of funding, its cap table may include dozens of shareholders holding common stock, preferred stock, options, warrants, SAFEs, convertible notes, and other instruments — each with different rights, preferences, and payout order in a liquidation or acquisition.

Types of Equity on a Cap Table

Common stock is the type of equity typically held by founders and employees. It represents ownership in the company but is subordinate to preferred stock in a liquidation, meaning preferred stockholders get paid first in an acquisition or bankruptcy. Employee stock options are rights to purchase common stock at a fixed price (the exercise price, also called the strike price) set at or above the fair market value of the stock at the time of grant, as determined by a 409A valuation. Options are typically granted subject to a vesting schedule.

Preferred stock is the type of equity held by venture capital investors. Preferred shares come with significant additional rights compared to common stock, including liquidation preferences (the right to receive their investment back before common shareholders receive anything in an exit), anti-dilution protection (which adjusts their ownership percentage if the company raises a subsequent round at a lower valuation), pro-rata rights (the right to invest in future rounds to maintain their ownership percentage), and information rights (the right to receive regular financial reports). The specific terms of preferred stock are negotiated in each funding round and documented in the Series Seed, Series A (or later series) term sheet and financing documents.

How Dilution Works

Dilution is the reduction in each existing shareholder's ownership percentage that occurs when new shares are issued to new investors, employees, or others. Dilution is a fundamental feature of venture-backed startup growth — every time the company raises money or expands its option pool, existing shareholders own a smaller percentage of a (hopefully) more valuable pie. Understanding dilution is essential for founders and employees to realistically assess what their equity is worth.

Consider a simple example: you own 100,000 shares out of 1,000,000 shares outstanding — 10% of the company. The company then raises a Series A round by issuing 500,000 new shares to investors. Your 100,000 shares now represent 100,000 out of 1,500,000 total shares — roughly 6.7% of the company. You have been diluted from 10% to 6.7%. If the new round was raised at a $15 million post-money valuation, however, the total value of the company is now higher, so the per-share value of your 100,000 shares may have increased even as your percentage decreased — this is the key insight: dilution is not inherently bad if each share is becoming more valuable as the company grows.

Employee Stock Options and Vesting

Employee equity is typically granted in the form of stock options — the right to purchase shares at a fixed strike price, typically after a vesting schedule is complete. The nearly universal standard vesting schedule for startup employees is four-year vesting with a one-year cliff: no options vest during the first year of employment (the cliff), then 25% vest all at once at the one-year anniversary, and the remaining 75% vest monthly (or quarterly) over the following three years. The cliff protects the company from early departures; the ongoing monthly vesting rewards continued tenure.

When an employee leaves the company, they typically have 90 days to exercise vested options before they expire. This creates a significant practical problem: early-stage company shares are illiquid (cannot easily be sold), but exercising options often requires paying both the exercise price and potentially substantial income taxes on the spread between exercise price and current fair market value. Many employees, particularly those who joined early when the 409A valuation was low and the stock's current fair market value is much higher, face difficult decisions about whether they can afford to exercise — and may lose valuable equity through no fault of their own. Some companies have extended exercise windows (to 5-10 years) to address this issue.

SAFEs and Convertible Notes

SAFEs (Simple Agreements for Future Equity), created by Y Combinator, and convertible notes are financing instruments commonly used in pre-seed and seed rounds as an alternative to a formal priced equity round. Rather than immediately determining the company's valuation and issuing shares at a specific price, these instruments allow the company to raise money now that will convert into equity at a discount to the next qualified funding round's price.

SAFEs and convertible notes typically include a valuation cap (the maximum valuation at which the instrument will convert, ensuring early investors get a good deal even if the company's valuation is much higher at the next round) and/or a discount rate (a percentage discount to the next round's price, typically 10-20%). When the qualifying round occurs, SAFEs and convertible notes convert to preferred stock at the more favorable of the cap or the discounted price. SAFEs are simpler than convertible notes — they have no interest rate, maturity date, or debt-like features — and have become the dominant instrument for early-stage financing in the US. However, multiple SAFEs at different cap levels can create a complex conversion waterfall that significantly dilutes founders when the price round occurs.

Pro Forma Cap Table and Fully Diluted Ownership

When evaluating equity ownership, it is essential to use the fully diluted cap table rather than the current capitalization. Fully diluted means counting all shares that could potentially exist if every option, warrant, convertible note, SAFE, and other convertible security were exercised or converted. This gives the most accurate picture of each party's ultimate ownership percentage.

Before each funding round, investors and founders work from a pro forma cap table — a modeled version of the post-round capitalization that shows what everyone will own after the new shares are issued and any prior SAFEs or notes convert. Investors invariably negotiate the size of the employee option pool as part of the round terms: enlarging the option pool before the round (rather than after) means the dilution of the pool creation falls on the pre-money shareholders (founders and existing investors) rather than the new investors — a negotiating point founders should clearly understand. Online cap table management tools like Carta, Pulley, and Capshare automate the complex math and help companies maintain legally compliant records as their cap tables grow in complexity.

How Payout Works in an Exit

• Step 1: Debt repayment — any outstanding debt (bridge loans, venture debt) is paid off first.
• Step 2: Liquidation preferences — preferred shareholders receive their liquidation preference (typically 1x the amount invested) before common shareholders receive anything. In a participating preferred structure, preferred shareholders then also participate pro-rata in the remaining proceeds alongside common shareholders.
• Step 3: Common stock distribution — after preferred preferences are satisfied, remaining proceeds are distributed to common stockholders (founders and employees) pro-rata by share count.
• Step 4: Taxes and fees — transaction fees, legal costs, and taxes reduce the net proceeds for all parties.

In a modestly successful acquisition where the exit price is only slightly above the total preferred investment, common stockholders (employees and founders) may receive little or nothing — illustrating why term sheet negotiation, particularly around liquidation preferences, is critically important to founders.
