The SaaS Cap Table Bible: The Complete Guide for Founders
The definitive guide to building and understanding cap tables. This guide walks through every component of equity management: founder splits, vesting schedules, option pools, dilution mechanics, preference stacks, and exit waterfalls. Written for founders raising from seed through Series B, and for any operator who needs to understand how equity works and how your ownership will evolve from day one through exit.
How cap tables work from founding through exit. Founder equity splits, vesting as protection, how dilution compounds across rounds, option pool mechanics, and the waterfall that determines who gets what at exit.

Part I: Cap Table Foundations
Chapter 1: What a Cap Table Is and Why It Matters From Day One
A capitalisation table, or cap table, is a spreadsheet showing exactly who owns what percentage of your company. It lists every shareholder, the number of shares they own, the class of shares, the price they paid, and the resulting ownership percentage. On the surface, it looks simple. Dig deeper, and a cap table becomes the single most important document in your company after your articles of association.
Most founders do not build a proper cap table until they are raising capital. This is a mistake. The decisions you make in year one about how to divide equity among founders, whether to use options for employees, and what dilution you accept from early investors will compound over seven years of operation and fundamentally shape the outcomes at exit.
A cap table serves three purposes. First, it is a legal document of record. Your cap table is audited by every investor before they invest. It determines the order of claims in a liquidation. It proves who owns what. Second, it is a strategic planning tool. By understanding how your ownership evolves across funding rounds, you can make better decisions about what terms to accept and what risk you are taking. Third, it is a communication tool. By sharing cap table transparency with your team, you help employees understand what their options are worth and how they benefit when the company succeeds.
The distinction between basic share count and fully diluted share count is critical. Your basic share count includes only common shares issued to founders and shares issued to employees who have exercised options. Your fully diluted share count includes all potentially dilutive securities: all unexercised options in the option pool, all warrants, and all convertible notes that could convert to equity. Investors care about fully diluted ownership because that is what they actually own assuming all dilution occurs.
Consider a simple example. You and a co-founder each own 1 million shares. That is 50/50 ownership on a basic share count of 2 million shares. But if you have granted options worth 500,000 shares to employees and created a 500,000 share option pool for future hires, your fully diluted share count is 3.5 million shares. Your founder ownership is now 57% on a fully diluted basis, not 50%. This is the ownership percentage that matters for your exit in three years.
How Cap Table Decisions in Year 1 Affect Exit in Year 7
This is the crucial insight that most founders miss. The decisions you make today about equity: who you give it to, how much, at what price, all compound over years. If you split 100 shares equally among three co-founders, you are each 33%. If one co-founder leaves in year two with a cliff, that 33% gets allocated back to the company option pool. But if you did not structure vesting with a cliff, your departing founder keeps their full allocation, and three years later at exit, 33% of your company is owned by someone who has not worked there in five years. This changes the entire waterfall and impacts what every remaining founder receives.
Similarly, the option pool you create at seed affects every round thereafter. If you create a 15% option pool at seed, every investor going forward expects that pool to be reserved for employees. If you later run out of options and need to create another pool, you are diluting existing investors. If you create a 5% pool at seed and end up needing 20%, you face a politically difficult mid-round dilution or you hire talent without options, which impacts recruiting.
Funding round terms also compound. A Series A investor who negotiates a lower valuation today does not just impact your Series A economics. Their valuation anchors the Series B valuation. If you accept a downround in Series B, anti-dilution provisions in your Series A might kick in and further dilute founders and employees. These cascading effects mean that short-term valuation decisions have seven-year consequences.
The takeaway: understand your cap table from day one, build it correctly, and review it quarterly as your company evolves.
Chapter 2: Founder Equity Splits
How you divide equity between co-founders is one of the most important decisions you will make as an early-stage founder. Get it wrong and you have friction, resentment, and legal disputes. Get it right and the split becomes irrelevant because you are all incentivised to build value together.
There are broadly three approaches to founder splits: equal, contribution-based, and role-based.
Equal splits (50/50, 33/33/33, 25/25/25/25) are the simplest and are appropriate when co-founders are joining at the same time, with similar experience, and expecting to work full-time on the company from day one. Equal splits are powerful because they signal that every founder matters equally, they are simple to explain, and they remove any perception of hierarchy or status. Many successful companies have used equal splits: Google (Page and Brin 50/50), Facebook (Zuckerberg and team roughly equal at founding, though Zuckerberg had more shares from earlier seed rounds), and Twitter (relatively equal among the early founding team).
Contribution-based splits attempt to allocate equity based on what each founder has already contributed: prior work, connections, capital, IP. This approach seems fair on the surface but is complex to implement and often becomes a source of tension. If one founder already has the initial code written and another is handling business development, how much should each receive? The question often cannot be answered objectively. Additionally, contribution-based approaches can demoralise later co-founders who feel they are starting from a disadvantage.
Role-based splits allocate equity based on expected future contribution. The founder who will be CEO might receive a premium. The CTO might receive a technical specialist premium. This approach can work but requires all founders to agree on roles upfront, which is not always possible when the business is evolving. It also creates an asymmetry that some founders dislike.
In practice, equal splits are most common and usually best. They avoid complex negotiations and send a clear signal of trust and alignment among founders. If there is a meaningful difference in commitment (one founder is joining part-time while another is full-time), that can be addressed through differential vesting schedules rather than different ownership percentages.
Vesting as Protection
Vesting protects both co-founders and the company. Without vesting, if a founder joins the company with 25% ownership and leaves two weeks later, they keep their 25%. With vesting, they keep only a small percentage and the rest is allocated back to the company option pool.
The standard schedule in Silicon Valley is 4-year vesting with a 1-year cliff. Under this arrangement, founder equity vests linearly over 4 years, but the founder must stay for at least 1 year to receive any equity. At the 12-month cliff, the founder receives 25% of their total grant (1 year of 4). From month 13 onwards, they vest 1/48th of their grant monthly. So a founder with 1 million shares vesting over 4 years with a 1-year cliff receives 250,000 shares at month 12, then 20,833 shares per month from month 13 onwards.
This schedule protects the company because a founder leaving in month 6 receives nothing. It also protects founders because if a founder is let go unfairly in month 24, they have already vested 50% of their grant and get to keep those shares. The cliff is particularly important because it prevents the "immediate vest" scenario where a founder stakes a large claim and contributes almost nothing.
Some companies use different vesting schedules for different founders. For example, a founder who has been working on the idea for six months before incorporation might have a 2-year vesting start date (credit for prior work) and then 3-year vesting thereafter. This is less common but can be fair when founders have meaningfully different start dates.
Acceleration Provisions
Acceleration provisions allow founder vesting to speed up in certain circumstances, typically in an acquisition. There are two types: single-trigger and double-trigger.
Single-trigger acceleration means that if the company is acquired, all vesting accelerates immediately (the founder gets all remaining unvested equity even if they were not working at acquisition). This is very founder-friendly but can create misaligned incentives. If a founder knows they will get all their equity upon acquisition regardless of whether they stay, they might leave before the integration process completes, which can harm the acquisition outcome.
Double-trigger acceleration means vesting accelerates only if two things happen: (1) the company is acquired, AND (2) the founder is fired or constructively dismissed in the acquisition. This is fairer to all parties because it protects founders from being fired in the acquisition without getting their equity, but it also requires founders to stay if they want the benefit. Double-trigger is more common among institutional investors because it creates better incentive alignment.
Chapter 3: Vesting Schedules and Cliff Provisions
Vesting schedules are far more important than most founders realise. They directly impact your cap table, your ability to recruit and retain talent, and your financial outcomes at exit.
The 4-year-with-1-year-cliff structure is standard for good reason. Four years is a reasonable time horizon for a founder to be substantially involved in building the business. One year is long enough to prove commitment but not so long that a co-founder is forced to stay in an unproductive situation.
The cliff serves two functions. First, it creates a natural reset point. If someone leaves before the cliff, they keep nothing and the company retains all options. If someone stays past the cliff, they have proven commitment and deserve to keep what they have earned. Second, the cliff creates a period where early disagreements can be resolved without large equity consequences. If you hire a VP of Engineering and they are not working out, you can make the change in month 11 with minimal equity impact.
For employees hired after the company is established (post-Series A), vesting schedules might be different. Early employees who joined at significant risk might get 4-year vesting with a 1-year cliff. Later employees with less risk might get 4-year vesting with a 6-month cliff. Executive hires sometimes get custom schedules based on negotiation.
One decision that founders often get wrong: whether to use monthly or yearly vesting. Monthly vesting (1/48th per month) is standard because it matches how quickly you actually benefit from an employee's work. Yearly vesting (25% after year one, then 25% per year) creates cliff effects at annual milestones that can feel arbitrary.
Part II: Funding Rounds and Dilution
Chapter 4: Pre-Money vs Post-Money Valuation and Dilution Mechanics
Understanding pre-money and post-money valuation is essential because one small error in your calculation changes your dilution by 5-10 percentage points.
Pre-money valuation is the value of your company before a new investment. Post-money valuation is the value after. If investors value your company at 6 million pounds pre-money and invest 1.5 million pounds, the post-money valuation is 7.5 million pounds. The formula is simple: Post-Money = Pre-Money + Investment Amount.
The investor's ownership percentage is calculated as: Investment Amount / Post-Money Valuation. In the example above, the investor owns 1.5m / 7.5m = 20% of the company post-round. Your founder ownership dilutes from 100% to 80% (assuming no option pool adjustment).
This is where the distinction between pre-money and post-money option pools becomes critical. If the investor negotiates a 15% option pool created from pre-money valuation, the pool comes out before the investment and reduces founder ownership immediately. If the option pool is created from post-money valuation, it comes out of the new ownership and affects the investor more.
Here is a worked example showing the difference. You have 10 million founder shares and are raising 1.5 million pounds at a 6 million pounds pre-money valuation.
Scenario A: Pre-Money Option Pool (15% of 6m pre-money)
Pre-money option pool reserve: 15% of 6m = 0.9m pounds of equity. At any price per share, this reserves equity. If the price per share is 0.6 pounds (6m valuation / 10m shares), the pool reserves 1.5m shares. The investor invests 1.5m pounds / 0.6 per share = 2.5m new shares. Post-round cap table: 10m founder shares + 1.5m option pool reserve + 2.5m investor shares = 14m total shares. Founder dilution: 10m / 14m = 71.4%. Investor owns 2.5m / 14m = 17.9%.
Scenario B: Post-Money Option Pool (15% of 7.5m post-money)
The investor invests at 0.6 per share (same price), purchasing 2.5m shares. The post-money valuation is 6m + 1.5m = 7.5m pounds. The option pool is 15% of 7.5m = 1.125m pounds of equity. At 0.6 per share, that is 1.875m shares. Post-round cap table: 10m founder shares + 1.875m option pool reserve + 2.5m investor shares = 14.375m total shares. Founder dilution: 10m / 14.375m = 69.6%. Investor owns 2.5m / 14.375m = 17.4%.
The difference seems small (71.4% vs 69.6%) but compounds through multiple rounds. Pre-money pools are friendlier to investors because they reduce founder ownership early. Post-money pools are friendlier to founders.
Chapter 5: Employee Option Pools
An option pool is a reserve of shares set aside for future employee grants. Instead of issuing shares to employees (which would dilute all shareholders immediately), companies grant options from the pool. When an employee exercises their options or they vest, the company can issue shares at that exercise price.
Why do investors require option pools? Because investors want to hire talented people without diluting themselves further. If you have closed a funding round and need to hire a VP of Sales, you cannot ask the investor to agree to another round of dilution. Instead, you draw from the pre-established option pool.
Typical pool sizes by stage: Seed stage companies usually allocate 10-15% of fully diluted shares to option pools. This is high because the risk is high and talent compensation via options is important. Series A companies typically allocate 10% of fully diluted shares. Series B and beyond, 5-10%. The logic is that earlier-stage companies have more risk and need to compensate with more options. Later-stage companies are more stable and can offer cash compensation.
There is an important distinction between option pool allocation and option pool creation. You can allocate pool shares upfront (they sit in a reserved bucket) or create them as needed. Creating them as needed is simpler but forces you to return to investors for approvals if you exceed your allocated amount.
Most common scenario: at Series A, investors negotiate an option pool size (usually 10% of fully diluted) and require a board seat and approval authority for option grants above a certain amount (usually any single grant over 1% of total shares). This protects investors from the company granting huge option blocks without oversight.
How Option Pool Grants Work
When you grant an option to an employee, you are granting them the right to purchase shares at a strike price (the fair market value of the stock on the grant date). You do not issue shares; you issue options that vest over time. When the employee exercises (purchases shares), they pay the strike price and receive shares.
Example: You hire a VP of Engineering at Series A when your fair market value is 0.6 pounds per share. You grant them 500,000 options with a 0.6 pound strike price. The grant is worth 0 pounds on day one (because strike price equals current price). Over four years, as the company's valuation increases, the options become valuable. If the company is acquired at 20 pounds per share, those 500,000 options are worth 19.4 pounds per share (the difference between the 20 pound sale price and the 0.6 pound strike price) times 500,000 shares = 9.7 million pounds. This is why option grants are the primary wealth creation vehicle for employees at startups.
Chapter 6: Seed Round Cap Table: A Real Example
Let us work through a realistic seed round cap table to make this concrete.
Initial State (Pre-Funding)
| Shareholder | Shares | % (Basic) | Notes |
|---|---|---|---|
| Founder A | 1,000,000 | 50% | 4-year vesting, 1-year cliff |
| Founder B | 1,000,000 | 50% | 4-year vesting, 1-year cliff |
| Totals | 2,000,000 | 100% |
Now the company raises a 1.5 million pound seed round on a 6 million pound post-money valuation. The lead investor is receiving Series Seed preferred shares. The terms include a 12% option pool created from post-money valuation.
Price Per Share Calculation
Post-money valuation includes the new investment. The investor's ownership will be 1.5m / 7.5m = 20%. Working backwards: if the investor owns 20% and invests 1.5m pounds, the company is worth 7.5m post-money. The price per share is 7.5m / (2m existing + new shares from investment) = 7.5m / total shares needed.
We need to solve: 1.5m pounds / price per share = new shares, and (2m + new shares) * price per share = 7.5m. Solving: price per share = 7.5m / (2m + 1.5m/price). This simplifies to: price = 0.60 pounds per share. Investor buys 1.5m / 0.60 = 2.5m shares.
Post-Seed Cap Table (Fully Diluted)
| Shareholder | Shares | % (Fully Diluted) | Notes |
|---|---|---|---|
| Founder A | 1,000,000 | 33.3% | |
| Founder B | 1,000,000 | 33.3% | |
| Seed Investor | 2,500,000 | 26.7% | Series Seed preferred |
| Option Pool | 900,000 | 6.7% | 12% of 7.5m post-money |
| Totals | 5,400,000 | 100% |
The founders have diluted from 100% to 66.7%. This is typical and acceptable for a seed round. They retain significant control and have capital to grow.
Chapter 7: Series A Cap Table Mechanics
Series A is fundamentally different from seed because it is a priced round. Investors are buying preferred shares with specific rights and protections, not convertible notes that will later be converted to equity.
A typical Series A works as follows. The company is valued at 20 million pounds pre-money (an arbitrary but realistic valuation for a seed-funded company that has grown). A Series A investor invests 5 million pounds. The post-money valuation is 25 million pounds.
Series A Calculation
The investor owns 5m / 25m = 20% post-round. The price per share is 25m / total fully diluted shares. But we need to know what "total fully diluted shares" is after all dilution, including Series A preferred shares, common shares, and the option pool.
Using the previous cap table as starting point: 5.4m existing fully diluted shares at 0.60 pounds per share (seed price). The Series A investor price per share is negotiated, but it is typically 3-5x the seed price for a company with good traction. Let us say 1.50 pounds per share.
At 1.50 pounds per share, the Series A investor invests 5m / 1.50 = 3.33m new shares. These are Series A preferred shares with different rights than the common shares held by founders and the option pool.
Post-Series A Cap Table (Fully Diluted)
| Shareholder | Shares | Price/Share | Investment | % (Fully Diluted) |
|---|---|---|---|---|
| Founder A (Common) | 1,000,000 | - | - | 15.8% |
| Founder B (Common) | 1,000,000 | - | - | 15.8% |
| Seed Investor (Pref) | 2,500,000 | 0.60 | 1.50m | 39.5% |
| Series A Investor (Pref) | 3,333,333 | 1.50 | 5.00m | 52.6% |
| Option Pool | 900,000 | - | - | 14.2% |
| Totals | 8,733,333 | - | 6.50m | 100% |
The founders have diluted from 66.7% to 31.6% combined. The Series A investor owns 52.6% on a fully diluted basis. This is typical for Series A: investors usually own 40-50% after the round, founders retain 25-40% combined, and employees have 15-25% reserved in the option pool.
The reason founders dilute more in Series A than seed is because Series A is a much larger check (5m pounds vs 1.5m pounds) and investors require significant ownership. Series A investors also want to ensure that founders are substantially diluted so they remain motivated but not overwhelmed by dilution in future rounds.
Chapter 8: Series B and Beyond: Cumulative Dilution
By Series B, the compounding effect of dilution becomes clear. Let us extend the example one more round.
The company is now valued at 50 million pounds pre-money (Series A was 20m pre-money; the company has grown significantly). A Series B investor invests 10 million pounds at a new price per share that reflects the higher valuation. Using the same methodology as Series A, the post-money is 60 million pounds, and the investor owns 10m / 60m = 16.7%.
The Series A investor negotiated a pro-rata rights clause, allowing them to participate in Series B to maintain their ownership percentage. The Series A investor invests an additional 2m pounds to maintain their 16.7% stake (approximately). This is common for lead investors.
Post-Series B Cap Table (Fully Diluted, Simplified)
| Shareholder | % (Fully Diluted) | Notes |
|---|---|---|
| Founder A | 9.2% | Starting 50%, now down to 9.2% |
| Founder B | 9.2% | Starting 50%, now down to 9.2% |
| Seed Investor | 12.1% | Starting 26.7%, down to 12.1% (diluted, no pro-rata rights) |
| Series A Investor | 16.7% | Maintained stake through pro-rata participation |
| Series B Investor | 16.7% | New investor |
| Option Pool & Employees | 36.1% | Expanded significantly for hiring |
| Totals | 100% |
Founders started at 50% each, dropped to 33.3% (seed), then to 15.8% (Series A), and now own 9.2% each at Series B. This is typical for founders who successfully raise Series B. The cumulative dilution of roughly 80% from founding to Series B is normal and expected. However, it illustrates why understanding the path early matters. If you accept unfavourable terms in Series A, you will be diluted more in Series B.
Chapter 9: Liquidation Preferences: 1x Non-Participating vs 2x Participating
A liquidation preference determines the order and amount of proceeds distributed to shareholders in a liquidity event (acquisition, sale, or liquidation). This is critical because it determines how much money founders actually receive at exit.
The two most common preference structures are 1x non-participating preferred and 2x participating preferred. The difference is substantial.
1x Non-Participating Preferred: Investors receive 1x their investment amount first (they get back what they invested), then participate pro-rata with common shareholders in any remaining proceeds. This is more founder-friendly because once investors have received their investment back, they do not get additional preference over common shareholders.
2x Participating Preferred: Investors receive 2x their investment amount first, then participate pro-rata with common shareholders in any remaining proceeds. This is more investor-friendly because they get extra preference and can even "double dip" by getting 2x and then participating again.
Let us work through a concrete example. Company exits for 30 million pounds. Three investors put in 1 million pounds each at Series A, Series B, and Series C, for a total of 3 million pounds invested.
Scenario A: 1x Non-Participating
Proceeds available: 30m. Preferred investors get 1x their investment: 3m (3 investors × 1m each). Remaining proceeds: 27m. This 27m is split pro-rata among all shareholders based on their ownership percentage. If founders own 30% of fully diluted shares, they get 30% of 27m = 8.1m. Total founder payout: 8.1m.
Scenario B: 2x Participating
Proceeds available: 30m. Preferred investors get 2x their investment: 6m (3 investors × 2m each). Remaining proceeds: 24m. This 24m is split pro-rata based on ownership. If founders own 30%, they get 30% of 24m = 7.2m. Total founder payout: 7.2m. The difference: 8.1m vs 7.2m = 900k less for founders.
This simple example shows why liquidation preference language matters. In a healthy exit where proceeds far exceed the amount invested, the preference is less impactful. In a down exit where proceeds are only slightly above amount invested, the preference can be very impactful.
The Waterfall: Who Gets What at Different Exit Prices
The full waterfall determines how proceeds are split across all claim classes. Working through the waterfall requires knowing: (1) total proceeds, (2) all preferred share classes and their preferences, (3) all common share classes, (4) fully diluted share count, and (5) pro-rata ownership percentages.
Let us work through a realistic waterfall for our Series B example.
Pre-Exit Cap Table (Fully Diluted)
| Class | Shares | Preference | % Ownership | Investment |
|---|---|---|---|---|
| Common (Founders) | 2,000,000 | None | 18.2% | 0 |
| Common (Employees) | 4,000,000 | None | 36.4% | 0 |
| Series Seed Pref | 2,500,000 | 1x non-participating | 22.7% | 1.5m |
| Series A Pref | 3,333,333 | 1x non-participating | 30.3% | 5.0m |
| Series B Pref | 1,666,667 | 1x non-participating | 15.2% | 2.5m |
| Total Preferred | 68.2% | 9.0m | ||
| Total Common | 31.8% | 0 | ||
| Total | 11,000,000 | 100% | 9.0m |
Waterfall at 45 Million Pound Exit (Healthy Exit)
Step 1: Preferred shareholders get 1x their investment in reverse order (Series B gets paid first). Series B gets 2.5m. Remaining: 42.5m. Series A gets 5m. Remaining: 37.5m. Series Seed gets 1.5m. Remaining: 36m.
Step 2: Remaining 36m is split pro-rata among all shareholders. Founders own 18.2%, so they get 6.55m. Employees own 36.4%, so they get 13.1m.
Total payouts: Founders: 6.55m. Employees: 13.1m. Investors: 2.5m + 5m + 1.5m = 9m. Total: 28.65m paid out. (The remaining 16.35m goes to taxes, transaction fees, etc.)
Waterfall at 15 Million Pound Exit (Down Exit)
Step 1: Series B gets 2.5m (all 15m is not enough for all preferences, so waterfall is impaired). Remaining: 12.5m. Series A investors are owed 5m but only 12.5m remains, so they only get 5m. Remaining: 7.5m. Series Seed investors are owed 1.5m but only 7.5m remains, so they only get 1.5m. Remaining: 6m.
Step 2: Remaining 6m is split pro-rata based on common share ownership. Founders own 18.2% of total shares but wait: in a down exit, preferred shareholders are in a superior position and get paid first. Common shareholders (founders and employees) share the remaining 6m pro-rata to their ownership of common shares. Founders own 2m / 6m = 33.3% of common shares, so they get 33.3% of 6m = 2m. Employees own 66.7% of common shares, so they get 4m.
Total payouts: Founders: 2m. Employees: 4m. Investors: 9m. Total: 15m. This illustrates why Series B terms matter. In this down exit, founders got 2m while investors got 9m. This is why understanding the waterfall before you take capital is important.
Chapter 10: Anti-Dilution Provisions
An anti-dilution provision protects preferred shareholders if the company raises capital at a lower valuation than their previous round. Without anti-dilution, investors simply dilute like everyone else. With anti-dilution, investors get additional shares to maintain their ownership percentage or their per-share price.
There are three types of anti-dilution provisions: broad-based weighted average, narrow-based weighted average, and full ratchet.
Broad-Based Weighted Average: This is the most common and fairest mechanism. If you raise a down round, the preferred investor's price per share is recalculated using a weighted average of the old price and new price, weighted by shares outstanding. This reduces dilution for the investor but is not as aggressive as full ratchet.
Example: Series A investor paid 1.50 pounds per share for 3.33m shares, investing 5m pounds. There are 6.73m fully diluted shares outstanding before Series B. Series B comes in at 1 pound per share (down round). There are 13m fully diluted shares after Series B.
Old price: 1.50. Old shares: 6.73m. New price: 1. New shares issued: 10m. Weighted average price = (1.50 × 6.73m + 1 × 10m) / (6.73m + 10m) = (10.095m + 10m) / 16.73m = 1.20 pounds. The Series A investor's new price is 1.20 pounds (down from 1.50 but not as bad as the full 1 pound). The investor receives additional shares: (5m / 1.50) - (5m / 1.20) = 3.33m - 4.17m = additional shares equal to the difference, which the company issues at no additional cost.
Narrow-Based Weighted Average: Similar to broad-based, but uses only shares actually outstanding, not fully diluted shares. This is more punishing to founders because it increases the weight of new shares in the calculation.
Full Ratchet: The investor's price per share drops all the way to the new down round price. This is very punishing to founders and common shareholders because it is very dilutive. Full ratchet is rare in institutional rounds but sometimes appears in high-risk seed financing.
Anti-dilution is standard in institutional rounds. Do not try to avoid it during fundraising. Instead, negotiate the type: broad-based weighted average is standard and fair. Avoid full ratchet at all costs.
Chapter 11: Board Control and Protective Provisions
As you raise capital, investors gain governance rights. These rights are usually expressed through board seats and protective provisions (veto rights on major decisions).
Typical board composition: At Series A, the investor usually gets one board seat and the founders/management team appoints the rest. So a typical Series A board might be: CEO (founder), investor director, one founder/executive, and one independent director. That is 4 board members.
At Series B, the Series B investor often gets a board seat as well. Now you have: CEO, Series A investor, Series B investor, one founder/executive, and perhaps an independent director. That is typically 5 board members.
Board control matters because control of the board determines the outcome of acquisitions, follow-on fundraising, and major strategic decisions. If investors control the board, they can force you to sell the company at a price you do not like. If founders maintain board control (usually by holding >50% of board seats), they can resist an unfavourable exit.
Protective provisions are veto rights that holders of preferred shares retain even if they do not have board control. Typical protective provisions include: raising new capital, acquiring another company, selling the company, declaring dividends, liquidating, changing board size, changing option pool size, or taking on debt above a certain threshold. These protections let minority shareholders block major decisions.
The key insight: board control and protective provisions give investors power without necessarily owning the company. A Series B investor with one board seat and protective provisions can control major decisions even if they own less than 10% of the company. This is why understanding governance is as important as understanding ownership percentages.
Chapter 12-15: Four Real Cap Table Examples
Example 1: Seed Stage Cap Table
Two founders, each starting with 500,000 shares (50/50 split, 4-year vesting with 1-year cliff). An angel investor invests 250,000 pounds at a 1 pound pre-money valuation, purchasing 250,000 shares. A 50,000 share option pool is created. Post-seed cap table: 1m founder shares (71.4%), 250k angel (17.9%), 50k option pool (3.6%), plus 200k shares reserved for future SAFEs or convertible notes (10.7%).
Example 2: Post-Series A Cap Table
Starting from example 1, the company raises Series A. Series A investor invests 1.5m pounds at 1.5 pounds per share, purchasing 1m shares. An additional 200k share option pool is created. Post-Series A: Founders 33.3% (500k shares each), Series A investor 25% (1m shares), angel 6.2% (250k shares), option pool 12.5% (500k shares total).
Example 3: Post-Series B Cap Table
Starting from example 2, Series B investor invests 3m pounds at 3 pounds per share, purchasing 1m shares. Series A pro-rata rights allow them to invest additional 1m for 333k shares. Option pool increases to 800k. Post-Series B: Founders 14% (500k shares each, or 28% combined), Series A investor 16.7%, Series B investor 16.7%, angel 6.2%, option pool 25%, employees 21.4%.
Example 4: Pre-Exit Cap Table and Waterfall
The company is valued at 100m pounds and receives an acquisition offer for 150m pounds cash. Preference stack: Series B has 1x non-participating, Series A has 1x non-participating, angel has 1x non-participating. Total preferential investment: 5m pounds.
Waterfall: Series B gets 3m (their investment), Series A gets 1.5m, angel gets 0.25m. Total to preferred shareholders: 4.75m. Remaining: 145.25m for common shareholders. Founders own 28% of common shares (14m fully diluted), so they receive 28% of 145.25m = 40.67m. Employees receive 21.4% of 145.25m = 31.1m.
Chapter 16: Cap Table Management Tools
For seed-stage companies, a spreadsheet is sufficient for cap table management. You can track shares, prices, vesting dates, and calculate dilution manually. However, this approach breaks down quickly as you add investors, options, and complexity.
Carta is the market leader for institutional cap table management. It handles version control, option tracking, 409A valuations, waterfall analysis, and integration with your equity software. Carta is used by most venture-backed companies.
Pulley is a newer player focused on simplicity and offering founders more transparency. It handles similar cap table management and also offers equity management (employees can see their options, exercise online, etc.).
Capdesk is popular in Europe and handles cap table management plus compliance and reporting across multiple jurisdictions.
Ledgy offers cap table management with a focus on Swiss startups but expands globally.
The decision between these tools is less important than the decision to use one. Spreadsheet cap tables cause problems: version control is terrible, errors are hard to catch, and they do not scale. Move to a professional tool before Series A.
One critical concept: 409A valuation. In the United States, the IRS requires that stock options be granted at fair market value (the price at which the stock would trade in a hypothetical arm's length transaction). For private companies, this is typically determined by a 409A valuation, which is an independent valuation by an expert. The 409A valuation affects the strike price of options and has tax implications for employees. You will need to obtain a 409A valuation before granting options at Series A and update it annually thereafter.

Conclusion: Cap Tables Are a Founder Tool, Not Just an Investor Document
Your cap table is not just for investors. It is a founder's tool for understanding your business, your ownership, and your path to wealth creation. By understanding cap tables deeply, you make better decisions about equity splits, you negotiate funding rounds more effectively, and you understand the financial outcomes that await you at exit.
The key principles to remember: (1) Vesting protects everyone. (2) Dilution compounds, so early decisions matter more than later ones. (3) Fully diluted ownership is what matters, not basic shares. (4) The waterfall determines outcomes, so understand preferences before you accept them. (5) Option pools are valuable but must be sized appropriately. (6) Board control and governance matter as much as ownership percentage.
Build your cap table correctly from day one, update it monthly, review it quarterly with your board, and let it guide your fundraising decisions. Your cap table is the financial map of your company from founding through exit.
