This article is for Irish startup founders preparing to raise investment who need to get their share capital structure investor-ready.
If you're wondering what share structure investors expect, how to clean up your cap table, or when to implement preference shares and vesting arrangements, this guide covers the pre-investment restructuring steps that prevent due diligence delays and deal-breakers.
Key Takeaways
• Start with ordinary shares for founders and a single share class to keep your structure simple and minimise costs.
• Investors require preference shares with liquidation preference, conversion rights, and anti-dilution protection to protect their investment.
• Create an employee option pool of 10-15% before investment, as this dilutes founders rather than investors and is market standard.
• Implement founder share vesting over 3-4 years with a one-year cliff before approaching investors to demonstrate commercial awareness.
• Clean up obvious problems like missing share certificates before fundraising, but wait for a signed term sheet before implementing full investor structure.

Why Does Share Capital Structure Matter?
Your share capital structure determines how ownership, control, and economic returns are divided among shareholders. Investors care deeply about this because it affects their rights, returns, and exit prospects.
A clean, simple structure signals professionalism and makes due diligence faster. Messy structures with multiple share classes, unclear ownership, or missing documentation create delays and reduce investor confidence.
What Should Your Pre-Investment Structure Look Like?
Before approaching investors, most Irish startups should have a straightforward structure that's easy to understand and modify.
Ordinary Shares for Founders
Founders typically hold ordinary shares with full voting rights and dividend entitlements. These shares should be properly issued with share certificates and recorded in statutory registers.
All founders should have signed founders agreements documenting their investment and any vesting arrangements. This prevents disputes about who owns what and under what conditions.
Single Share Class Initially
Starting with one class of ordinary shares keeps things simple and minimises incorporation costs but you can also create preference shares and other classes to get ahead of the game.
Avoid creating multiple founder share classes with different voting rights unless you have specific governance reasons. This complexity rarely helps and often creates problems during investment negotiations.
Adequate Authorised Share Capital
Your authorised share capital should provide room for growth without requiring constitutional amendments.
Setting authorised capital too low means amending your constitution before each funding round. In our experience, setting it higher costs nothing but provides flexibility when you need it.
What Share Structure Do Investors Expect?
Investors typically require specific share structures that protect their investment and provide preferential rights over ordinary shareholders. These structures are set out below.
Preference Shares for Investors
Why Investors Want Preference Shares
Preference shares protect investors from downside risk while preserving upside potential. If the company fails, they get paid before founders receive anything.
On successful exits, conversion rights let investors participate as ordinary shareholders and share in the full upside. This structure gives them better returns in success while limiting losses in failure.
Creating New Share Classes
Creating preference shares after incorporation requires amending your constitution through a special resolution. This involves passing a 75% shareholder vote and filing a Form B10 with the Companies Registration Office. This is why it can help to create them in advance.
Investors will typically specify the exact rights they want in their term sheet. Your solicitor then drafts constitutional amendments creating the new share class with those rights.
What Are Common Pre-Investment Restructuring Steps?
Most companies need some restructuring before investment to create an investor-friendly structure.
Employee Share Option Pool
Investors typically require you to create an option pool of 10-15% of fully diluted share capital before investment. This ensures employee incentives don't dilute the investors' stake.
The option pool dilutes founders rather than investors, which feels unfair but is market standard. Pushing back on this rarely succeeds and signals inexperience with fundraising norms.
Removing Inappropriate Share Classes
If you've created unnecessary share classes or given shares to advisors with odd rights, clean this up before approaching investors. Messy cap tables create due diligence headaches and delay closings.
Buy back advisor shares that were issued too generously or convert them to options instead. Remove any share classes that don't serve clear governance purposes.
Vesting Founder Shares
Most investors require founder shares to vest over 3-4 years with a one-year cliff. This protects the company if founders leave early and aligns founder incentives with long-term success.
Implementing vesting after investment is more complex than doing it before. Setting it up early demonstrates commercial awareness and prevents last-minute negotiations.
What Do Investor-Friendly Articles Look Like?
Your constitution (articles of association) needs specific provisions that investors expect to see in Irish companies.
Tag-Along Rights
Tag-along rights let investors sell their shares alongside founders if founders receive a purchase offer. This prevents founders from exiting while investors remain stuck in the company.
The provisions typically require founders to ensure any purchaser buys investor shares on the same terms. Refusing to grant tag-along rights is a deal-breaker for most investors.
Drag-Along Provisions
Drag-along provisions let majority shareholders force minority shareholders to join in approved sales. This prevents small shareholdings from blocking valuable exit opportunities.
Investors want these provisions to ensure they can exit when they choose. The threshold for activating drag-along rights is typically 75% shareholder approval.
Pre-emption Rights on Share Issues
Board Representation
Investors typically negotiate board seats or observer rights as part of investment. Your articles should provide flexibility for the board size to increase when investors join.
Include provisions allowing investor directors to be appointed and removed by the investor shareholders. This gives investors control over their board representation without needing shareholder meetings.
What Information Should You Have Ready?
Proper documentation prevents due diligence delays and demonstrates professionalism to investors. The essential share capital documents are set out below.
Essential Share Capital Documents
Cleaning Up Your Cap Table
Your capitalisation table should clearly show all shareholders, their shareholdings, and ownership percentages on both an issued and fully diluted basis.
Include all options granted but not yet exercised, showing exercise prices and vesting schedules. Investors want to see exactly what dilution they're facing from existing commitments.
Documentation Requirements
Each grant needs proper option agreements documenting exercise price, vesting schedule, and any performance conditions. Board minutes should approve grants and confirm they fall within the authorizsd pool.
Keep a separate register of options showing grantee, grant date, vesting schedule, and exercise status.
When Should You Restructure?
Timing your restructuring carefully balances preparation costs against deal certainty.
Before Approaching Investors
Clean up obvious problems like missing share certificates or inaccurate registers before you start fundraising conversations. These issues make you look unprofessional and create unnecessary friction.
Implement founder vesting if you haven't already, as this will definitely be required. Create adequate authorised share capital to avoid mid-deal constitutional amendments.
After Terms Are Agreed
Wait until you have a signed term sheet before implementing the full investor-preferred structure. Creating preference shares and complex constitutional provisions costs money and may not match what investors ultimately require.
The term sheet will specify exactly what structure investors need. Implementing it after agreement prevents wasted work if terms change or deals don't close.
