A cap table (short for capitalization table) is the definitive record of who owns what in a company. It tracks every share of common stock, every class of preferred stock, every option grant, every warrant, and every convertible instrument outstanding. If equity is the currency of startups, the cap table is the ledger.
What a Cap Table Contains
At its simplest, a cap table lists shareholders and their ownership percentages. In practice, it is far more layered:
- Common stock. Held by founders, employees who have exercised options, and sometimes early advisors.
- Preferred stock. Issued to investors in each priced round (seed, Series A, Series B, etc.), with each series carrying its own rights and preferences.
- Stock options. Granted to employees and advisors under the company’s equity incentive plan. The cap table tracks granted, vested, exercised, and available (unallocated) options.
- Convertible instruments. SAFEs and convertible notes that will convert into equity at a future trigger event, typically the next priced round.
- Warrants. Rights to purchase shares at a specified price, sometimes issued alongside venture debt or as part of strategic partnerships.
Why Cap Tables Matter
Every fundraising negotiation starts with the cap table. Investors need to understand the existing ownership structure before they can evaluate what their investment buys. A clean cap table signals operational rigor. A messy one signals risk.
Specific issues investors flag during due diligence:
- Too many small holders. A cap table with dozens of angel investors creates administrative burden and potential consent issues for future rounds.
- Founder equity imbalances. A co-founder with a disproportionately small stake (or no vesting) raises red flags about team stability.
- Missing or incomplete records. Unsigned stock purchase agreements, option grants without board approval, or SAFEs without proper documentation can delay or kill a deal.
- Excessive dilution. If founders own less than 50% before a Series A, later-stage investors worry about motivation and alignment.
Cap Table Modeling
Before any fundraise, founders should model the cap table impact of different scenarios. This means running the math on various pre-money valuations, round sizes, and option pool expansions to understand how each scenario affects ownership.
Key modeling exercises include:
- Fully diluted ownership. Calculates ownership assuming all options, warrants, and convertible instruments convert into common stock. This is the number investors use.
- Waterfall analysis. Models how proceeds from a sale or liquidation flow to each shareholder class based on liquidation preferences and participation rights.
- Future round dilution. Projects how ownership changes through subsequent rounds to ensure founders retain enough equity to stay motivated and aligned.
Keeping It Clean
Cap table management should start at incorporation and stay current through every transaction. Most early-stage companies use dedicated cap table software (Carta, Pulley, AngelList) rather than spreadsheets, though a well-maintained spreadsheet works at the earliest stages. The key is that every share issuance, option grant, and convertible instrument is recorded accurately and backed by signed legal documents. Cleaning up a cap table retroactively is one of the most expensive and time-consuming exercises in startup operations.
Frequently Asked Questions
What is included in a cap table?
A cap table includes all classes of equity (common stock, preferred stock from each funding round), stock options (granted and exercised), warrants, convertible notes, SAFEs, and any other instruments that can convert into equity. It tracks the number of shares, ownership percentage, vesting schedules, and exercise prices for each holder.
When should a startup create a cap table?
At incorporation. Even a two-person founding team needs a cap table from day one. Early decisions about founder splits, advisor grants, and the initial option pool all need to be recorded. Cleaning up a messy cap table retroactively is expensive and time-consuming, and investors will flag it during due diligence.
How does a cap table change during a funding round?
When a new round closes, new shares are issued to investors, increasing the total share count. Existing holders' share counts stay the same, but their ownership percentages decrease (dilution). Any convertible instruments (SAFEs, notes) that convert in the round add additional shares. The option pool may also be expanded, which creates new authorized but unissued shares.
