Key Takeaways
- A cap table tracks who owns what — shares, options, SAFEs, and all other equity instruments in your company
- Investors review it before your pitch deck to assess deal structure, red flags, and founder alignment
- Calculate on a fully diluted basis — this is the number that matters most
- Typical dilution ranges: 10–15% at pre-seed, ~20% at seed, 15–25% at Series A
- A messy or inaccurate cap table is one of the quickest ways to stall a funding round
What Is a Cap Table?
A cap table — short for capitalization table — is a document that records who owns what in your company. At its simplest, it's a spreadsheet with names, share counts, and ownership percentages. At its most complex, it's a multi-tab model tracking common stock, preferred stock, option grants, vesting schedules, SAFEs, convertible notes, and how all of those convert across multiple funding rounds.
Think of it as your company's financial DNA. Every equity decision you make — from splitting shares with a co-founder to giving your first advisor 0.5% — gets recorded here. And unlike your pitch deck (which tells a story) or your financials (which project a future), your cap table tells the truth about who has skin in the game and how much.
For pre-seed and seed-stage startups, most cap tables start simple: two or three founders, maybe an advisor, and a small option pool. But the decisions you make at this stage compound. Getting the structure wrong early can mean spending years cleaning it up — or discovering at Series A that your cap table needs significant work before institutional investors will engage.
Why Investors Ask for Your Cap Table on Day 1
Here's something that often surprises first-time founders: many investors will ask for your cap table before they ask for your pitch deck. Not after. Before.
Why? Because your cap table answers every question they actually care about upfront: How much of the company is available? How much dilution have the founders already taken? Are there any unusual agreements or side letters that could complicate the deal? Is the option pool sized correctly, or will they need to negotiate an expansion that further dilutes the founders?
Why This Matters
A cap table is one of the first documents reviewed during venture due diligence. It shows how control, ownership, and incentives are distributed between founders, employees, and investors. If it's inaccurate or incomplete, investors can't assess how much equity founders and employees will hold after a new round — which directly impacts motivation and long-term alignment.
Investors are pattern-matching machines. A clean cap table signals discipline. A messy one raises questions about how the company is run. As one investor from Silicon Valley Bank put it: having a clean cap table signals to investors that your company is well-run and worth supporting with venture investment.
What a Cap Table Includes
A well-built cap table contains more than just names and percentages. Here's every element investors expect to see:
| Component | What It Tracks | Why It Matters |
|---|---|---|
| Security Holders | Names of every individual and entity that owns equity | Identifies who has a claim on the company |
| Common Stock | Shares held by founders, employees, and early advisors | The base layer of ownership — what founders typically hold |
| Preferred Stock | Shares held by investors (Series Seed, A, B, etc.) | These carry liquidation preferences and special rights |
| Stock Options | Granted, vested, exercised, and unexercised options | Shows employee equity commitment and pool utilisation |
| SAFEs / Convertible Notes | Outstanding instruments that convert to equity later | Creates "hidden" dilution — critical to model |
| Warrants | Rights to purchase shares at a set price | Often issued alongside debt or as advisor compensation |
| Option Pool (Unallocated) | Shares reserved for future hires | Investors will negotiate this — it comes out of founders' stake |
| Ownership % | Both undiluted and fully diluted percentages | Fully diluted is what actually matters to investors |
| Vesting Schedules | When shares are earned over time (usually 4 years, 1-year cliff) | Protects against co-founder departure |

Real Cap Table Example: Pre-Seed Stage
Let's walk through what a real pre-seed cap table looks like. This is a two-founder company that has set aside an option pool and brought on two advisors before raising any external capital:
| Security Holder | Type | Common Shares | Options Outstanding | Total Securities | Fully Diluted % |
|---|---|---|---|---|---|
| Founder #1 (CEO) | Founder | 7,500,000 | 40,000 | 7,550,000 | 58.98% |
| Founder #2 (CTO) | Founder | 1,800,000 | 50,000 | 1,850,000 | 14.45% |
| Employee #1 | Employee | 0 | 60,000 | 75,000 | 0.59% |
| Employee #2 | Employee | 0 | 1,000,000 | 1,000,000 | 7.81% |
| Advisor #1 | Advisor | 0 | 5,000 | 5,000 | 0.04% |
| Advisor #2 | Advisor | 0 | 5,000 | 5,000 | 0.04% |
| Investor #1 | Investor | 0 | — | 500,000 | 3.91% |
| Investor #2 | Investor | 0 | — | 500,000 | 3.91% |
| Unallocated Option Pool | Pool | — | 185,000 | 185,000 | 1.45% |
| Total | 9,300,000 | 2,395,000 | 12,800,000 | 100.00% |
A few things to notice here. The founders collectively own 73.43% on a fully diluted basis, which is healthy at this stage. The option pool is relatively small (1.45% unallocated), which means they'll likely need to expand it before a priced round. The two investors hold preferred stock through a previous small round.
Watch Out
Notice the 60/15 founder split. Lopsided ownership between co-founders (anything beyond 60/40) will raise questions from investors. While it's not a deal-breaker — sometimes one founder contributed far more early capital or IP — you should be prepared to explain the reasoning. Investors prefer evenly distributed equity among co-founders.
Undiluted vs Fully Diluted: The Number That Actually Matters
This is where first-time founders get tripped up. There are two ways to calculate ownership:
Undiluted ownership counts only shares that have actually been issued and are currently outstanding. It ignores options that haven't been exercised, SAFEs that haven't converted, and the unallocated option pool.
Fully diluted ownership assumes every option, warrant, SAFE, and convertible note has been exercised or converted into shares. This is the number investors care about, because it reflects the "real" economics of the company if every equity instrument becomes actual stock.
Fully Diluted Ownership % = Your Shares ÷ (All Outstanding Shares + All Options + All Convertibles) × 100
Here's why this matters: a founder might own 75% of outstanding common stock (undiluted), but only 55% on a fully diluted basis once you account for the option pool and investor SAFEs. That 20-percentage-point gap is real money at exit. Make sure you know your fully diluted number.
How Dilution Works: The Maths Behind Shrinking Ownership
Dilution isn't a bad thing by default. It's the mathematically inevitable result of creating new shares. Every time your company issues equity — to investors, employees, or through conversion of SAFEs — the total share count increases. Your shares stay the same, but the pie gets bigger, so your slice gets proportionally smaller.
The basic dilution formula is straightforward:
Post-Round Ownership % = Pre-Round Shares ÷ (Pre-Round Total Shares + New Shares Issued) × 100
For example: if you own 7,500,000 shares out of 10,000,000 total (75%), and the company issues 2,500,000 new shares to a seed investor, you now own 7,500,000 out of 12,500,000 — or 60%. You didn't lose any shares. But your ownership percentage dropped from 75% to 60%. That's dilution.

Typical Dilution by Funding Stage (2025–2026 Benchmarks)
Based on data from thousands of funding rounds, here are the current median dilution figures founders should expect:
| Stage | Typical Dilution | Median Raise | Median Valuation | Source |
|---|---|---|---|---|
| Pre-Seed | 10–15% | $650K–$700K | $3.95M–$7M post-money | Metal, Carta 2025 |
| Seed | ~19–20% | $4.0M | $20M post-money | Carta State of Seed 2025 |
| Series A | 15–25% | $5M–$15M | $20M–$60M pre-money | EquityList, Rebel Fund 2025 |
Note how dilution at seed has fallen slightly in recent years — down from the historical 20–25% range to about 19%. This is partly because SAFEs (which now account for 92% of pre-seed rounds) defer pricing, and partly because founders with strong traction are commanding higher valuations.
Benchmark to Remember
Target ownership benchmarks for founders: 80–90% post-seed, 50–70% post-Series A, and 30–45% post-Series B. If you're below these ranges, review your deal terms carefully — you may be giving away too much too early.

How SAFEs and Convertible Notes Appear on Your Cap Table
This is where cap tables get tricky for first-time founders. SAFEs (Simple Agreements for Future Equity) and convertible notes are the most common instruments for pre-seed and seed fundraising. They're fast, cheap, and simple to execute. But they create a problem: they represent future equity that doesn't show up as actual shares until a triggering event (usually a priced round).
Until conversion, SAFEs and notes sit on your cap table as a separate category — not as shares, but as obligations to issue shares later. The challenge is modelling what happens when they convert.
Key terms that determine conversion:
| Term | Definition | Typical Range |
|---|---|---|
| Valuation Cap | The maximum valuation at which the SAFE/note converts — protects early investors from high future valuations | $3M–$17M (varies by stage and market) |
| Discount Rate | Percentage discount to the next round's price per share | 20% (used in 63% of SAFEs) |
| Interest Rate | Annual interest accrued on convertible notes (not SAFEs) | 2–8% |
| Cap Type | Pre-money or post-money cap — determines the denominator for conversion | Post-money (YC standard since 2018) |
The critical distinction most founders miss: post-money SAFEs (the current YC standard) include the SAFE itself in the valuation cap, which means the dilution is fixed and predictable at the time of signing. Pre-money SAFEs and convertible notes are more complex because the dilution depends on the conversion price at the next round.
Common Trap
Raising large sums through multiple SAFEs before a priced round can lead to significant "stacking" dilution that surprises founders when everything converts at once. Model the fully converted cap table before signing each new SAFE. If you have $500K in SAFEs at a $5M post-money cap, that's 10% dilution locked in — and it adds up fast when you stack three or four SAFEs.

The Option Pool: The Equity You're Already Giving Away
The option pool is shares reserved for future employees, advisors, and contractors. It's typically part of the negotiation when you raise a priced round, and here's the key detail: investors typically require the option pool to be created before their investment, which means the dilution comes entirely from the founders' share — not the investors'.
Typical option pool sizes by stage:
| Stage | Option Pool Size | Purpose |
|---|---|---|
| Pre-Seed / Seed | 10–15% | First 10–15 hires, early advisors |
| Series A | 10–15% expansion | Growth team, department leads |
| Series B+ | 5–10% expansion | Key executives, retention |
Advisor equity typically ranges from 0.1% to 1% depending on their involvement, with total advisor allocations rarely exceeding 2% of the cap table. Standard vesting for advisors is 2 years with no cliff (monthly vesting), compared to 4-year vesting with a 1-year cliff for employees.
Negotiation Tip
When investors ask for a 20% option pool at Series A, push back. Calculate exactly how many shares you need for your hiring plan over the next 18 months and justify a smaller pool (often 10–12% is sufficient). Every percentage point of unnecessary option pool comes directly out of founder equity. Negotiate pools on a post-money basis when possible to reduce this effect.
How to Build Your Cap Table: Step by Step
Ideally, create your cap table the day you incorporate — not when investors ask for it, but from the start.
Step 1: Authorise your shares. When you incorporate, you'll authorise a total number of shares. A common starting point is 10,000,000 shares. This is the total supply. You'll issue some and keep the rest in reserve.
Step 2: Allocate founder shares. Split equity among founders. Document the split, put it in writing, and vest all founder shares (typically 4-year vesting, 1-year cliff). Yes, even if there's only one founder. This protects the company.
Step 3: Create the option pool. Set aside 10–15% for future employees and advisors. Don't allocate individual grants yet — just reserve the shares. This signals to future investors that you've planned ahead.
Step 4: Record everything. Every equity transaction gets documented: grant date, number of shares, share class, vesting schedule, exercise price. No verbal promises. No handshake deals. Every commitment in writing.
Step 5: Model your first raise. Before approaching investors, model what happens to the cap table under different scenarios: What if you raise $500K at a $5M cap? $1M at a $10M cap? How does the option pool expansion affect founder ownership? Run the numbers before the negotiation, not during it.
Spreadsheet vs Software: When to Switch
| Spreadsheets | Cap Table Software | |
|---|---|---|
| Best for | Pre-seed, 1–15 stakeholders, no convertible instruments | Post-seed, 15+ stakeholders, SAFEs converting, option grants |
| Cost | Free | Free tier (Carta up to 25 stakeholders) → $100+/mo |
| Pros | Full control, customisable, no vendor lock-in | Automation, compliance, scenario modelling, investor portal |
| Cons | Formula errors, version control headaches, no audit trail | Cost, learning curve, potential vendor dependency |
| Switch when | You raise a priced round, have 15+ option holders, or investors request Carta access |
Popular cap table software options: Carta (industry standard, free for up to 25 stakeholders), Pulley (advanced modelling and scenario planning), AngelList Stack (free for investors, integrated fundraising), and SeedLegals (UK-focused legal + cap table).
7 Cap Table Mistakes That Stall Fundraising Deals
These are mistakes that have slowed or derailed funding rounds for otherwise promising companies.
1. Not vesting founder shares. If a co-founder leaves after 6 months and retains 40% of the company, your startup faces a significant structural challenge. Standard vesting (4-year, 1-year cliff) protects everyone. Most investors will pass on a company where founder shares aren't vested.
2. Giving away too much equity too early. Founders who give 30%+ to early investors or advisors before seed are making their Series A negotiation much harder. Most industry experts suggest selling 20–35% at Series A. If you've already given away 40% before that, the maths doesn't work.
3. Verbal equity promises without documentation. "I'll give you 5% when we raise" means nothing legally and everything emotionally. Undocumented promises create disputes. Every equity commitment must be formalised in writing and reflected in the cap table.
4. Not modelling SAFE/note conversion. Stacking multiple SAFEs without modelling how they convert is a common surprise at Series A. Founders who raised $750K across three SAFEs at different caps often discover they've given away 25–30% before the priced round even starts.
5. Calculating ownership on an undiluted basis. You think you own 65%. Investors see 48% on a fully diluted basis. Surprise. Calculate and communicate ownership using fully diluted shares.
6. Creating complex share classes early. Multiple share classes with different voting rights, conversion ratios, or liquidation preferences at the pre-seed stage is a red flag. Keep it simple: common stock for founders and employees, preferred stock for investors. Full stop.
7. Not updating the cap table in real time. Every equity event — grant, exercise, termination, transfer — should be reflected immediately. A cap table that's 6 months out of date can cause real problems during due diligence.

What Investors Red-Flag on Your Cap Table
Beyond the obvious mistakes, experienced investors pattern-match for specific structural issues:
Founders below 50% collectively before Series A. If the founding team doesn't hold majority ownership before institutional money comes in, investors question the long-term motivation and control dynamics. Target: founders should hold 80–90% post-seed collectively.
Dead equity. Shares held by people who are no longer involved with the company — departed co-founders, early advisors who aren't contributing, or ex-employees with fully vested shares. Dead equity means less room for people who are actually building the company.
Unusual side letters or preferences. Early investors with board seats, super pro-rata rights, anti-dilution ratchets, or participating preferred at the seed stage. These make future rounds harder to structure and scare off institutional investors.
No option pool or a depleted one. If you've allocated all your options already, the Series A investor will demand a new pool — and it will be sized on a pre-money basis, which means the dilution hits founders disproportionately.
Inconsistent data. If the numbers on your cap table don't match your board minutes, stock ledger, or legal documents, that's a due diligence failure. This can slow or derail a deal.
Cap Table Management: Best Practices
Managing a cap table isn't a one-time exercise. It's an ongoing discipline that compounds in value as your company grows. Here are the practices that separate investor-ready companies from the rest:
Designate a cap table owner. One person (typically the CEO, CFO, or legal counsel) is responsible for maintaining accuracy. No shared-editing spreadsheets floating around with three different versions.
Update in real time. Every equity event gets recorded immediately: new hires, option grants, advisor agreements, SAFE issuances, exercises, terminations. Batch updates create gaps.
Maintain a single source of truth. Whether it's a spreadsheet or Carta, there is one authoritative version. Everything else is a copy.
Run scenario analyses regularly. Before every fundraise, model at least 3–5 scenarios: different raise amounts, different valuations, different option pool sizes. Understand how each scenario affects founder ownership, investor returns, and employee equity.
Prepare for continuous due diligence. Your cap table should be investor-ready at all times — not just when you're actively fundraising. Institutional investors, acquirers, and even key hires may request it on short notice.
Control access. Not everyone needs to see every cell. Share what's necessary: employees can see their grant details, investors can see the full cap table, but individual salary-related options should be private.
Frequently Asked Questions
When should I create a cap table?
The day you incorporate. Even if it's just you and a co-founder splitting shares 50/50, documenting ownership from the start prevents future disputes and establishes a clean paper trail investors will expect.
What's the difference between undiluted and fully diluted ownership?
Undiluted counts only currently outstanding shares. Fully diluted includes all shares that could exist — outstanding shares plus all stock options, warrants, and convertible securities as if they had all been exercised or converted. Investors typically look at fully diluted numbers.
How much equity should I give away at pre-seed?
The current market benchmark is 10–15% dilution at pre-seed, based on 2025 data from Carta and Metal. The median pre-seed raise is around $650K–$700K with a median valuation of $3.95M–$7M post-money.
Should I use a spreadsheet or cap table software?
Spreadsheets are fine at pre-seed with fewer than 15 stakeholders and no convertible instruments. Move to software (Carta, Pulley, or AngelList Stack) once you raise a priced round, issue stock options, or have SAFEs converting — the complexity makes spreadsheets error-prone.
What if an investor asks for my cap table and it's messy?
Fix it before sharing. Hire a startup lawyer to reconcile your cap table with your legal documents. It's cheaper to clean up now ($2K–$5K in legal fees) than to lose a funding round because of avoidable errors.

Frequently Asked Questions
What is a cap table?
A cap table (capitalization table) is a document — typically a spreadsheet — that records who owns what percentage of your company. It tracks every share issued, every option granted, and every investment received, including common stock, preferred stock, options, warrants, SAFEs, and convertible notes.
When should I create a cap table?
Create your cap table the day you incorporate. Even if it's just you and a co-founder splitting shares, documenting ownership from the start prevents future disputes and establishes a clean paper trail investors will expect.
What is the difference between undiluted and fully diluted ownership?
Undiluted ownership only counts currently outstanding shares. Fully diluted ownership includes all shares that could exist — outstanding shares plus all stock options, warrants, and convertible securities (SAFEs, notes) as if they had all been exercised or converted. Investors typically look at fully diluted numbers.
How much equity do founders typically give up at each stage?
At pre-seed, founders typically give up 10-15% equity. At seed, dilution is usually around 19-20%. At Series A, founders typically sell 15-25%. By Series B, cumulative dilution often means founders hold 30-45% collectively. These are medians — actual figures depend on traction, market, and negotiation.
Should I use a spreadsheet or software for my cap table?
Spreadsheets are fine for pre-seed and early seed stages with fewer than 10-15 stakeholders. Once you raise a priced round, issue employee options, or have convertible securities converting, professional cap table software (like Carta, Pulley, or AngelList Stack) reduces errors and simplifies compliance.
