What Is a Cap Table and Why Should You Care Right Now

A capitalization table (cap table) is a spreadsheet that tracks the ownership of your company. It lists every shareholder, how many shares they hold, what class of shares those are, and what percentage of the total they represent on both a basic and fully diluted basis. In the early days, your cap table is simple: the founders own 100% of the company. Once you take money from investors, issue options to employees, or sign any convertible instruments, the cap table becomes more complex. And complexity, if not managed carefully, becomes a problem. The reason cap table literacy matters before you raise is straightforward: the decisions you make in your first round create a structural baseline that compounds through every future round. A cap table that is poorly structured at seed will create friction at Series A and real problems at Series B and exit. Here is a real pattern I have seen repeatedly. A founder raises a small pre-seed round, issues shares informally, never sets up a proper option pool, and moves fast. Two years later, a serious institutional investor runs a fully diluted analysis and finds that the founder's ownership stake has already been diluted to a level that creates misaligned incentives for the founder to keep building. The institutional investor hesitates. The deal slows. In some cases it dies. Get this right early.

The Core Concepts

Authorized Shares vs. Issued Shares

Authorized shares are the total number of shares your company is legally permitted to issue, as set in your articles of incorporation. Issued shares are the ones that have actually been allocated. You do not need to issue all authorized shares immediately. Most companies authorize more than they issue to give themselves flexibility. Basic vs. Fully Diluted Ownership

Basic ownership counts only issued shares. Fully diluted ownership counts everything: issued shares, options granted, options reserved but ungranted, warrants, and any convertible instruments that could convert into shares. Investors always quote ownership on a fully diluted basis. When a VC says they want 20% of the company for a given check, they mean 20% of the fully diluted share count post-investment. Pre-Money vs. Post-Money Valuation

Pre-money valuation is what your company is worth before the investment. Post-money valuation is what it is worth immediately after the investment is received. Post-money = Pre-money + Investment amount

Investor ownership = Investment amount / Post-money valuation Example: You raise GBP 1.5M at a GBP 6M pre-money valuation. Post-money is GBP 7.5M. The investor owns 1.5 / 7.5 = 20%. This is the single most important calculation in any term sheet. Make sure you are comparing pre-money to pre-money, or post-money to post-money. Mixing them up is a common source of confusion when reading term sheets.

How Dilution Works in Practice

Dilution means your ownership percentage decreases as new shares are issued. Your absolute number of shares stays the same. Your percentage of the total decreases. Example over three rounds:

At Series A, a founder who started at 100% now owns approximately 51%. This is healthy dilution. It means the company raised meaningful capital from reputable investors, and the founder still has a majority stake before the employee option pool is factored in. A founder who started at 60% because of an early co-founder split and took a large pre-seed round on a low valuation might be at 30% by the time they reach Series A. That is where problems start.

The Option Pool: What It Is and How It Affects You

An employee stock option pool (ESOP) is a block of shares reserved for employee grants. Options give employees the right to buy shares at a fixed price (the strike price) at a future date, subject to a vesting schedule. Most institutional investors will require you to have an option pool in place before they invest, typically 10 to 20% of the fully diluted cap table. The critical point is when the pool is created relative to the investment. If the pool is created before the investment (pre-money), it dilutes the founders, not the investor. This is called the option pool shuffle, and it is one of the most common and least-discussed ways that term sheets reduce effective founder economics. Example: You negotiate a GBP 6M pre-money valuation. The investor requires a 15% option pool to be created before closing. The effective pre-money valuation of the shares the founders actually hold is not GBP 6M. It is GBP 5.1M. The 15% pool was carved out before the valuation was applied. This does not mean you should refuse to create an option pool. You need one to hire good people. But you should negotiate the size carefully and understand the impact before you sign. A reasonable option pool at seed is 10 to 12% for most companies. If an investor asks for 20% upfront, ask them to model the hiring plan that justifies it. The pool size should be tied to a specific 18 to 24 month hiring plan, not a round number.

SAFEs and Convertible Notes: Cap Table Complexity Before You Even Raise

If you have raised money via a SAFE (Simple Agreement for Future Equity) or a convertible note, those instruments do not appear as shares today. They will convert into shares at your next priced round, typically at a discount to the round price or at a valuation cap, whichever is more favorable to the investor. This means your current cap table understates your fully diluted ownership picture. Before you model your fundraising, you need to model the conversion of all outstanding SAFEs and notes and understand what your fully diluted cap table looks like on the day the next round closes. Two things to check:

1. If you have multiple SAFEs with different valuation caps, the ones with the lowest caps will convert at the most shares, meaning the most dilution to existing shareholders. 2. If your priced round valuation is below the SAFE cap, the SAFE converts at the round price, which means no discount to the new investor and the most dilution to the founders. Always model your cap table post-conversion before entering a priced round negotiation.

What Investors Are Looking For in Your Cap Table

When an institutional investor reviews your cap table, they are checking four things: Clean structure. All shareholders are on one document. No side letters or informal agreements that are not captured. No missing option grant paperwork. No shares issued to people who left without a buyback or cliff. Founder motivation. If the founding team collectively owns less than 30 to 35% of the fully diluted cap table at seed, this is a yellow flag. Investors want founders to have meaningful ownership to maintain long-term motivation. Low founder ownership can also signal earlier decisions that were made under pressure or without proper advice. No messy early investors. Unsophisticated angel investors who were given large stakes on low valuations with no pro-rata rights or drag-along provisions can complicate future rounds. Sophisticated investors will want a clean cap table with standard institutional terms. Option pool headroom. Is there enough room in the option pool to hire the team required to justify the round being raised? If the answer is no, the investor will require a refresh before or alongside the investment.

The One Tool You Need

Use either Carta or Pulley to manage your cap table from day one. Both platforms track shares, options, vesting schedules, SAFEs, and generate waterfall analyses automatically. The cost at early stage is low. The cost of managing your cap table in a spreadsheet and then having to reconstruct it for a Series A data room is very high. If you are pre-revenue and have not yet raised any external capital, you can start with a simple spreadsheet. The moment you issue shares to anyone outside the founding team, move to a proper platform.
