1. Equity and Share Ownership
1.1 The Founders agree that equity in the Company shall be allocated as follows: Founder 1 ([Founder1 Name]): [Founder1 Equity] Founder 2 ([Founder2 Name]): [Founder2 Equity] Employee Option Pool: [Option Pool] 1.2 All shares are subject to the vesting schedule set out in Clause 2 of this Agreement. 1.3 Any future issuance of shares shall require the approval of the Founders in accordance with Clause 4, and shall be subject to pre-emption rights in favour of existing shareholders unless waived by special resolution.
2. Vesting Schedule
2.1 All Founder shares are subject to a [Vesting Period] vesting schedule commencing on [Agreement Date], with a [Cliff Period] cliff. 2.2 CLIFF: No shares shall vest during the cliff period. If a Founder ceases to be actively involved in the Company before the end of the cliff period, that Founder shall forfeit all their shares (or be required to sell them at nominal value as set out in Clause 3). 2.3 POST-CLIFF VESTING: Following the cliff, shares shall vest in equal monthly instalments over the remainder of the vesting period. 2.4 ACCELERATION: Single-trigger acceleration on acquisition applies: [Acceleration On Exit]. Where applicable, all unvested shares shall immediately vest on a change of control (acquisition, merger, or asset sale) of the Company. 2.5 All vested shares remain subject to the transfer restrictions in the Company's constitution and any applicable shareholders' agreement.
3. Founder Departure
3.1 GOOD LEAVER: A Founder who ceases active involvement due to death, serious illness, or by mutual written agreement of all Founders shall be treated as a 'Good Leaver' and may retain their vested shares at fair market value. 3.2 BAD LEAVER: A Founder who resigns without agreed cause, is dismissed for cause (including breach of this Agreement, fraud, or serious misconduct), or engages in competitive activities during the vesting period shall be treated as a 'Bad Leaver'. A Bad Leaver must sell all unvested shares and, at the Company's discretion, all vested shares at nominal value (€0.001 per share). 3.3 On departure (Good or Bad Leaver), the departing Founder's directorship and officer roles shall terminate automatically unless otherwise agreed in writing. 3.4 NON-COMPETE: For a period of [Non Compete Period] following departure, the departing Founder shall not directly or indirectly engage in any business that competes with the Company's core business as carried on at the date of departure.

What Is a Co-Founder Agreement (Ireland)?
A Co-Founder Agreement in Ireland governs the relationship between shareholders and the company and the terms on which equity is held, issued, or transferred, as regulated by the Companies Act 2014.
When Do You Need a Co-Founder Agreement (Ireland)?
A Co-Founder Agreement is needed whenever parties in Ireland wish to formalize their arrangement regarding business operations, corporate governance, and commercial transactions. There are numerous situations in which this document becomes essential for protecting the interests of all involved parties. In a business context, you may need a Co-Founder Agreement when entering into new commercial relationships, when formalizing existing arrangements that have previously been informal, when expanding your business operations, or when restructuring existing agreements. Companies registered with CRO should confirm proper documentation is maintained for all significant business transactions. You should also consider using a Co-Founder Agreement when there has been a change in circumstances that affects an existing arrangement, when you need to comply with new regulatory requirements, when you wish to update outdated documentation, or when professional advisors recommend formalizing certain aspects of your affairs. In Ireland, maintaining current and accurate legal documentation is considered established standards and can help prevent costly disputes. It is generally advisable to prepare a Co-Founder Agreement before any issues arise, rather than trying to document terms after a dispute has already begun. Proactive documentation provides clarity and reduces the potential for misunderstandings. If you are unsure whether you need this document for your specific situation in Ireland, consulting with a qualified legal professional can provide guidance tailored to your circumstances. The timing of executing a Co-Founder Agreement is also important. In Ireland, certain documents must be executed before specific actions are taken or within prescribed time periods to be effective. Delaying the preparation of necessary legal documents can result in complications, lost rights, or additional costs. Therefore, it is recommended to prepare this document as early as possible once the need has been identified.
What to Include in Your Co-Founder Agreement (Ireland)
A well-drafted Co-Founder Agreement for use in Ireland should contain several essential elements to confirm it is legally effective and provides adequate protection for all parties. Party Identification: The document should clearly identify all parties involved, including their full legal names, addresses, and relevant identification numbers. For individuals in Ireland, this may include identity card or passport numbers. For companies, registration numbers and registered addresses should be specified. Clear identification prevents disputes about who is bound by the agreement. Recitals and Background: The document should include background information explaining the context and purpose of the arrangement. This helps establish the parties' intentions and can be important in interpreting the terms of the document if any ambiguity arises later. The recitals section provides valuable context for the operative provisions that follow. Operative Terms: The core terms and conditions should be set out clearly and thoroughly. This includes the rights and obligations of each party, any conditions or prerequisites, the duration of the arrangement, and any limitations or restrictions. All key terms should be defined precisely to avoid ambiguity and potential disputes. Payment and Financial Terms: Where applicable, the document should specify any payments, fees, deposits, or other financial considerations. The amounts, currency (EUR), payment schedules, and methods of payment should be clearly stated. Any provisions for late payment, interest charges, or adjustments should also be included. Term and Termination: The document should specify its duration, including the start date, end date or conditions for expiry, and any provisions for renewal or extension. The circumstances under which either party may terminate the arrangement early should be clearly defined, along with any notice requirements and the consequences of termination. Dispute Resolution: The document should include provisions for resolving any disputes that may arise, such as negotiation, mediation, arbitration, or litigation. In Ireland, parties may choose to specify the jurisdiction of Irish courts and the applicable law. Including a clear dispute resolution mechanism can save significant time and expense if disagreements occur. Governing Law and Jurisdiction: The document should specify that it is governed by the laws of Ireland and that disputes shall be subject to the jurisdiction of Irish courts. This is particularly important in cross-border transactions or where parties are based in different jurisdictions. Signatures and Execution: The document must be properly signed by all parties or their authorised representatives. In Ireland, certain documents may need to be witnessed, notarised, or executed as deeds to be legally effective. The date of execution should be clearly recorded, and each party should retain an original signed copy for their records.

Frequently Asked Questions
A co-founder agreement is one of the most important documents an Irish startup can have. Without it, disputes over equity, roles, intellectual property, and decision-making can destroy a business. Irish company law under the Companies Act 2014 does not automatically address the internal relationship between founders — it merely sets out minimum corporate governance requirements. A co-founder agreement supplements the company's constitution by establishing: how equity is divided; what happens if a founder leaves early (vesting); who owns intellectual property created before and after incorporation; how key decisions are made and what happens in deadlocks; each founder's roles and time commitment; and what happens on exit (sale, IPO, or winding up). Enterprise Ireland, which funds many Irish startups, expects co-founder agreements to be in place before providing significant investment. Investors and VCs will also conduct due diligence on founder arrangements before committing funds.
Equity vesting is a mechanism by which a founder's shares are 'earned' over time rather than granted in full on day one. The most common structure for Irish startups is a four-year vesting schedule with a one-year cliff — meaning no shares vest in the first year, and then shares vest monthly over the following three years. If a founder leaves before the cliff, they forfeit all unvested shares. This protects the remaining founders and the company from a situation where a departing founder retains a significant equity stake without contributing to the company's growth. Vesting is typically implemented in Irish companies through a combination of the shareholders' agreement, the company's constitution, and share purchase agreements. When Enterprise Ireland or other Irish government bodies invest, they often require founder vesting as a condition of funding. Irish tax implications of share vesting are governed by the Taxes Consolidation Act 1997 and Revenue guidance on employee share schemes.
Under Irish law, intellectual property created by an employee in the course of their employment generally belongs to the employer under Section 21 of the Copyright and Related Rights Act 2000 (for copyright works) and common law principles (for other IP). However, co-founders who work on a startup before formal incorporation or employment contracts are entered into may personally own the IP they create. This is a critical risk area for Irish startups. A co-founder agreement should include a thorough IP assignment clause under which each founder assigns all IP created before and after incorporation to the company. The assignment should cover: copyright works, software, trade secrets, inventions, patents, trade marks, domain names, and know-how. The assignment must be in writing and signed to be effective under Irish law. Irish startups seeking investment from Enterprise Ireland, the European Innovation Council, or VCs will be required to demonstrate clean IP ownership.
An Irish co-founder agreement should clearly address what happens when a founder leaves the company — whether voluntarily ('good leaver') or involuntarily ('bad leaver'). Good leaver provisions typically allow the departing founder to retain vested shares at fair market value. Bad leaver provisions (e.g. dismissal for cause, breach of the agreement, or competitive activities) typically require the departing founder to sell unvested and sometimes vested shares at nominal value (e.g. €0.001 per share). The agreement should also address: non-compete and non-solicitation obligations post-departure (which must be reasonable in scope, duration, and geographic area to be enforceable under Irish law); whether the departing founder's role on the board terminates automatically; and how the value of shares is determined on exit. The Workplace Relations Commission (WRC) and Irish courts will scrutinise overly restrictive post-employment restraints.
A Co-Founder Agreement in Ireland does not legally require a solicitor — founders may draft and sign the document independently, as the Companies Act 2014 imposes no statutory requirement for legal representation in founder agreements. However, obtaining advice from a solicitor experienced in Irish company and startup law is strongly advisable given the long-term financial and legal consequences involved. A solicitor can draft bespoke vesting schedules enforceable under Irish law, structure IP assignments effectively under Section 21 of the Copyright and Related Rights Act 2000, advise on Revenue implications of founder share schemes under the Taxes Consolidation Act 1997, and require that non-compete and non-solicitation clauses comply with the restraint of trade doctrine as applied by the High Court of Ireland. Enterprise Ireland requires founder agreements to be in place before providing HPSU investment, and institutional investors conducting due diligence will scrutinise the document carefully. The Companies Registration Office (CRO) maintains the company register and any shareholders' agreement provisions that affect the company's constitution must be consistent with the Companies Act 2014. Disputes between founders may be adjudicated by the High Court under Section 212 of the Companies Act 2014 (oppression remedy) or by arbitration under the Arbitration Act 2010. The forms-legal.com Co-Founder Agreement (Ireland) template covers the core elements for Irish startups and can be a starting point before engaging a solicitor for the final version.
