Startup Cap Tables Explained: What Every Australian Founder Needs to Know

Most founders first look at their cap table seriously when they are about to raise — and discover it is messier than they expected.
The equity arrangement with the co-founder was never properly documented. The advisor was given shares without a vesting schedule. The friends-and-family round was done informally and the exact terms are unclear. There are three different share classes and nobody is entirely sure what rights each carries.
Now there is an interested investor doing due diligence and the cap table is the first thing they are going to scrutinise.
The time to understand and manage your cap table is before that moment, not during it.
Here is what you need to know.
What a Cap Table Is
A capitalisation table — cap table — is the document that records who owns what in a company. It lists every shareholder, the type of securities they hold, the number of shares, the percentage ownership and, in more detailed versions, the terms and conditions attached to each holding.
The cap table is not just an administrative record. It is the legal foundation of the company's ownership structure. Every investment decision, every equity grant, every option allocation is reflected in it. When a company raises capital, is acquired or goes through any significant corporate transaction, the cap table determines who gets what.
A clean, well-maintained cap table is a signal of good governance. A messy one — with inconsistencies, undocumented arrangements or unclear terms — is a red flag for investors and a complication in any future transaction.
What Goes on the Cap Table
Ordinary Shares
Ordinary shares are the standard equity issued to founders at incorporation. They carry voting rights and entitlement to dividends and proceeds on liquidation, typically after preference shareholders are satisfied.
Founders' shares are usually the largest component of the cap table and are subject to vesting schedules if the company has properly structured the co-founder arrangement.
Preference Shares
Most institutional investors — VCs and sophisticated angel investors — receive preference shares rather than ordinary shares. Preference shares have specific rights that ordinary shares do not: a liquidation preference (the right to receive their investment back before ordinary shareholders in a sale or liquidation), anti-dilution protection and often dividend preferences.
Understanding the terms of any preference shares in the cap table is essential — particularly the liquidation preference, which can significantly affect founder returns in an exit scenario.
Option Pool (ESOP)
The employee share option pool is an allocation of equity reserved for current and future employees, advisors and contractors. Options are typically granted with a vesting schedule and an exercise price.
The size of the option pool is negotiated as part of most institutional investment rounds — investors typically want to see a pool of 10–15% of the post-money cap table. If the pool needs to be created or expanded before the round, it dilutes existing shareholders rather than the new investor — making pre-round pool creation a negotiating point.
Convertible Instruments (SAFEs and Notes)
SAFEs and convertible notes sit on the cap table as instruments that will convert to equity at a future priced round. Their impact on the cap table is not visible until conversion — but their dilutive effect should be modelled before they are issued so founders understand what the post-conversion cap table will look like.
The Key Cap Table Calculations
Ownership Percentage
The basic calculation: shares held ÷ total shares outstanding = ownership percentage.
On a fully diluted basis — which includes all outstanding shares, options, warrants and convertible instruments as if they had all been exercised or converted — the calculation includes all potential equity, not just issued shares. Investors almost always discuss ownership on a fully diluted basis.
Dilution
Dilution is the reduction in ownership percentage that results from issuing new shares. When a company raises capital by issuing new shares, the total number of shares increases — and each existing shareholder's percentage decreases proportionally.
Example: A founder owns 1,000,000 of 2,000,000 shares outstanding (50%). The company issues 500,000 new shares in a seed round. Total shares outstanding become 2,500,000. The founder now owns 1,000,000 of 2,500,000 shares — 40%. They have been diluted by 10 percentage points.
Pro Rata Rights
Pro rata rights give existing investors the right to participate in future funding rounds in proportion to their current ownership — to maintain their percentage rather than being diluted by new investors.
Pro rata rights are a standard feature of most institutional investment terms. Understanding which shareholders have pro rata rights — and what the obligation to offer them participation looks like — is important preparation for future raises.
Building a Clean Cap Table From the Start
The cap table decisions made in the earliest stages of a startup have compounding consequences. Decisions that feel minor at the beginning — issuing shares without proper documentation, granting equity without vesting, accepting investment without clear terms — become significant complications when the business is raising institutional capital or approaching an exit.
The Founding Equity Split
Every co-founder's equity should be:
Agreed in writing before incorporation
Reflected accurately in the initial share register
Subject to a vesting schedule with a one-year cliff

Early Investor Documentation
Friends-and-family investments — however informal the relationship — should be documented with proper legal agreements. The specific terms (amount, instrument type, conversion terms or equity percentage) should be clear, written and executed by both parties.
Informal investments — "I'll put in $20,000 and we'll figure out the equity later" — create cap table ambiguity that is extremely difficult to resolve cleanly at a later stage.
Advisor Equity
Advisor equity should be small (0.1–0.5%), vested over 12–24 months and documented in an advisor agreement. Unvested advisor equity should have a mechanism for return if the advisor relationship ends before vesting is complete.
Option Pool Timing
Creating the employee option pool before it is needed — rather than under pressure during a fundraising process — gives founders more control over the pool size and timing of dilution.
Cap Table Management Tools
For early-stage startups, the cap table can be managed in a spreadsheet. As the company raises institutional capital and the cap table becomes more complex — multiple share classes, convertible instruments, option grants, pro rata rights — a dedicated cap table management tool becomes valuable.
Australian startups commonly use platforms such as Carta (global, widely used by institutional VCs) or Captable.io for cap table management. These tools automate dilution calculations, model future rounds and generate the documentation investors expect to see in due diligence.
Whatever tool is used, the cap table should be updated promptly after every transaction — every share issuance, option grant, conversion event or transfer — so it is always an accurate current record.

Frequently Asked Questions About Startup Cap Tables
What is a startup cap table? A cap table (capitalisation table) is the document that records who owns what in a company — every shareholder, the type of securities they hold, the number of shares and their ownership percentage. It is the legal foundation of the company's ownership structure.
What is a fully diluted cap table? A fully diluted cap table includes all outstanding shares plus all potential shares — options, warrants, convertible instruments — as if they had all been exercised or converted. Investors always discuss ownership on a fully diluted basis.
How do I keep my cap table clean? Document every equity transaction properly from day one. Use vesting schedules for all co-founder and advisor equity. Use formal agreements for all investments however informal the relationship. Update the cap table promptly after every transaction. Consider using a cap table management tool once the company has more than a handful of shareholders.
What is an option pool and why does it matter? An option pool is an allocation of equity reserved for employees, advisors and contractors. It is typically 10–15% of the fully diluted cap table post-institutional investment. Creating the pool before a round dilutes existing shareholders — understanding this timing is important in negotiations with investors.
What happens to the cap table in a funding round? New shares are issued to the investor. The total shares outstanding increase. All existing shareholders' percentage ownership decreases proportionally — they are diluted. The new post-money cap table reflects the new ownership structure including the investor's stake.

A Clean Cap Table Is a Commercial Asset
Investors who review a clean, well-maintained cap table with proper documentation move through diligence faster and with more confidence. Investors who review a messy cap table — with undocumented arrangements and unclear terms — slow down, ask more questions and sometimes walk away.
