What a Cap Table Is, in One Sentence
A cap table (capitalization table) is a single document that lists every owner of your company and exactly how much of it they hold. That is it. It shows the founders, the option pool, and every investor, with share counts and ownership percentages, so anyone can see who owns what and what happens to those numbers when you raise.
For a first-time founder, the cap table is the scoreboard of your fundraising. Every SAFE you sign, every priced round you close, every option you grant shows up here. Get it right and every future round is clean. Get it wrong and you will spend a lawyer's fees untangling it before your Series A.
The cap table only starts to matter once you have investors on it. If you are still looking for those first backers, Round Funded gives you 10,000+ active investors filtered by stage and sector, so you fill your cap table with the right names.
The Columns Every Cap Table Has
A cap table is a table, and its columns are always roughly the same: the owner, what kind of security they hold, how many shares, and what percentage that represents. Once you know the columns, you can read any cap table.
The standard columns:
| Column | What it shows |
|---|---|
| Shareholder | The person or entity that owns equity (founder, investor, employee, pool) |
| Security type | Common stock, preferred stock, SAFE, convertible note, or options |
| Shares | The raw number of shares or units held |
| Ownership % | That holder's share of the total, as a percentage |
| Fully-diluted % | The percentage if every option and convertible converted to shares |
The two percentage columns are where founders get confused. The plain ownership percentage counts only issued shares. The fully-diluted percentage assumes every option in the pool and every SAFE or note has converted. Investors almost always negotiate and think in fully-diluted terms, because that is the real picture of who will own what after everything settles.
What "Fully Diluted" Actually Means
Fully diluted means counting every share that could exist, not just the shares issued today. This is the number that matters when you raise, because your investor is buying a percentage of the fully-diluted company, not the smaller issued-only version.
Three things get counted in the fully-diluted total that are easy to forget:
- The option pool. Even unallocated options count. A 15% pool dilutes everyone, whether or not those options are granted yet.
- SAFEs and convertible notes. These are promises of future shares. On a fully-diluted basis they are treated as already converted at their cap.
- Warrants. Any right to buy future shares (common with venture debt) counts too.
Here is the trap: a founder looks at the issued-only table, sees 60% next to their name, and celebrates. But with a 15% pool and $1.5M of SAFEs sitting at a $10M cap, the fully-diluted number is much lower. Always read the fully-diluted column. That is the one investors read.

How a Priced Round Changes the Cap Table
A priced round issues new preferred shares to investors, which increases the total share count and reduces everyone else's percentage. This is the single event that reshapes a cap table the most, and the pre-money option pool is where founders lose the most ownership without noticing.
Walk through a simplified seed round:
- Two founders each hold 4,000,000 shares (8,000,000 total, 50/50).
- They agree to a $2M seed at an $8M pre-money valuation, so a $10M post-money.
- The investor wants a 15% option pool created pre-money.
- The investor buys 20% ($2M / $10M).
After the round, the founders no longer own 50% each. The new pool and the new preferred shares both come out of the pre-round holders (the founders), so their combined stake drops well below 80%. The math is unforgiving, and it is exactly why you model the round on the cap table BEFORE you sign.

Where Round Funded Fits: Fill the Cap Table With the Right Names
Round Funded is upstream of the cap table. A clean, valuable cap table is one filled with active, credible investors who back your stage. The hard part is not the spreadsheet; it is getting those investors to say yes in the first place.
Round Funded solves the actual bottleneck:
| The cap table problem | How Round Funded helps |
|---|---|
| An empty cap table with no investors | 10,000+ active investors, filtered by stage, sector, and geo |
| Wasting time on dormant funds | Filter by last-investment date to reach only active investors |
| No way to run outreach at scale | Send personalized emails and track opens and replies |
| Not knowing who fits your round | Match your startup profile to investors who invest in it |
A cap table with the wrong investors, or no investors, is a bigger problem than any formatting mistake. Start by filling it with the right ones.

Step by Step: Building Your First Cap Table
Here is the practical path for a founder starting from zero.
- List your founders and their shares. Start with the founder split. Use Round Funded to line up the investors who will eventually join this table.
- Add your option pool. Reserve 10% to 15% for early hires. Decide whether it is created pre-money or post-money, because it changes your dilution.
- Record every SAFE and note. Log the amount, the valuation cap, and any discount for each. Missing SAFEs is the most common cap table error.
- Model your next round. Before you raise, add a mock priced round and watch your fully-diluted percentage move. No surprises at signing.
- Pick a tool. A clean Google Sheet is fine at pre-seed. Move to Carta, Pulley, or Ledgy once you close a priced round.
- Keep one source of truth. Never let two versions of the cap table exist. Update it the day anything changes.
Frequently Asked Questions
Do I need a cap table before I raise money?
Yes, even a simple one. As soon as you have cofounders and an option pool, you have ownership to track. Investors will ask for it during diligence, and a clean cap table signals a serious founder. Once you are ready to raise, find the investors to add via Round Funded.
What is the difference between issued and fully-diluted shares?
Issued shares are the ones actually granted today. Fully-diluted shares include everything that could convert: the whole option pool, all SAFEs and notes, and any warrants. Investors negotiate on the fully-diluted number because it reflects who will really own what after all conversions.
What tool should I use for my cap table?
At pre-seed, a well-structured Google Sheet is perfectly fine and free. Once you close a priced round with preferred stock and multiple investors, move to a dedicated platform like Carta, Pulley, or Ledgy. They handle 409A valuations, option grants, and scenario modeling automatically.
What is the most common cap table mistake?
Forgetting to include the option pool and outstanding SAFEs when calculating dilution. Founders read the issued-only percentage, feel safe, and get shocked at their real fully-diluted stake at the next round. Always model the fully-diluted picture, including your next planned round.
Who should be able to see my cap table?
Your cofounders, your lawyer, and your investors during diligence. It is a sensitive document, so it is not public, but every current and prospective investor will review it. Keeping it clean and current is part of running a fundable company. Find those investors on Round Funded.
How does the option pool affect my ownership?
A larger option pool means more dilution for founders, especially when investors require it be created pre-money. A 15% pre-money pool comes entirely out of the founders' stake before the investor's money even lands. It is a real negotiation point in every priced round.
The Cap Table Follows the Round
A cap table is just a scoreboard. It records the decisions you make when you raise, grant options, and negotiate terms. The document is easy. The hard part, the part that actually determines whether your cap table is worth anything, is landing the investors who fill it.
Do not obsess over spreadsheet formatting while your cap table sits empty. Get active investors to the table first.
