Launching a business with co-founders can be one of the most rewarding experiences for entrepreneurs, but it also brings a unique set of legal and practical challenges. Many founders make the mistake of skipping or rushing through the process of documenting their relationship, only to face confusion or disputes later about ownership, roles, or decision-making. Others are unsure how a founders agreement fits with state filings or internal governance documents. This guide is designed for US founders, operators, and small business owners who want to understand how to use a founders agreement to clarify expectations, avoid common pitfalls, and ensure their business is set up for long-term success. We will cover what a founders agreement is, what it should include, how it interacts with state and federal requirements, and practical steps for drafting and maintaining your agreement.
What Is a Founders Agreement?
A founders agreement is a private contract among the original owners of a startup or small business. While it is not required by law, it is one of the most important documents you can create when starting a business with others. The agreement sets out each founder's rights, responsibilities, and expectations, helping to prevent misunderstandings and disputes down the road.
Typical provisions in a founders agreement include:
- Equity ownership and vesting: How much of the company does each founder own? Will ownership vest over time to encourage commitment?
- Roles and responsibilities: What is each founder's title and what are their day-to-day duties?
- Decision-making and voting: How will major and minor decisions be made? What voting thresholds are required?
- Intellectual property (IP) assignment: Will founders assign any inventions or IP to the company?
- Founder departures: What happens if a founder leaves, is terminated, or becomes unable to participate?
- Confidentiality and non-compete: Will founders be restricted from competing with the company or disclosing confidential information?
- Dispute resolution: How will disagreements be handled?
For example, three friends start a software company. They verbally agree to split ownership equally, but one founder leaves after a few months. Without a written agreement and vesting schedule, that founder could claim one-third of the company, even though they contributed little. A founders agreement with a vesting schedule would have prevented this scenario.
While a founders agreement is an internal document, it must work together with your company's other legal documents, such as bylaws (for corporations), operating agreements (for LLCs), and shareholder agreements. Inconsistencies can create confusion or even legal risk.
Federal and State Filing Considerations
At the federal level, there is no requirement to file a founders agreement. The IRS does not review or require this document. However, when you apply for an Employer Identification Number (EIN), you will need to provide information about your business structure and ownership. This is usually straightforward, but you should ensure your internal agreements match what you report to the IRS to avoid confusion later.
State requirements are more complex and vary by jurisdiction. When you form a legal entity, such as a corporation or LLC, you must file certain documents with your state's Secretary of State (or, in Delaware, the Division of Corporations). These filings typically include:
- Articles of Incorporation (for corporations) or Articles of Organization (for LLCs)
- Registered agent information
- Initial reports or statements of information (required in some states)
- Filing fees
The founders agreement itself is not filed with the state. However, your state may require you to adopt bylaws (corporations) or an operating agreement (LLCs). These documents may be required to be kept internally or, in rare cases, filed with the state. For example:
- Delaware: Does not require bylaws or operating agreements to be filed, but you must have them internally.
- California: Requires corporations to adopt bylaws and LLCs to have an operating agreement, but these are not filed with the state.
- New York: Requires LLCs to adopt a written operating agreement within 90 days of formation, but it is not filed with the state.
- Texas: Does not require filing of bylaws or operating agreements, but you must have them internally.
It is important that the information in your founders agreement aligns with your state filings and internal governance documents. For example, if your articles of incorporation list one person as president, but your founders agreement names someone else, this inconsistency could create confusion or even legal disputes. Always double-check for alignment before signing or filing any documents.
Some states have unique requirements. For example, in California, if your founders agreement includes provisions about board composition or voting rights, these must not conflict with state corporate law or your bylaws. In New York, LLCs must have a written operating agreement, and your founders agreement should not contradict it. If you are forming in Delaware, the state is known for its flexibility, but you still need to ensure all documents are consistent.
Practical tip: Before filing your entity formation documents, review your draft founders agreement and make sure all names, roles, and ownership percentages match. This will help avoid headaches later if you need to prove ownership or authority to banks, investors, or regulators.
Key Points to Cover in a Founders Agreement
Every business is unique, but there are several key issues that most founders agreements should address. Here is a breakdown of what to include, with practical examples and state-law caveats:
- Equity Split and Vesting: Decide how ownership will be divided. Many startups use a four-year vesting schedule with a one-year cliff, meaning no equity vests until the founder has stayed for one year, then monthly vesting after that. This is especially important for attracting investors. In California, vesting is common and expected by most venture capitalists.
- Roles and Titles: Specify who will be CEO, CTO, COO, etc. Define responsibilities to avoid overlap or confusion. For example, in a tech startup, the CTO might oversee product development while the CEO handles fundraising and operations.
- Decision-Making and Voting: Clarify how decisions are made. Will all decisions require unanimous consent, or will some be made by majority or supermajority vote? For corporations, this should align with your bylaws. In LLCs, your operating agreement may set out voting rules.
- IP Assignment: Require each founder to assign any relevant intellectual property (such as code, inventions, or trademarks) to the company. This is critical for protecting your business and is often required by investors. In Delaware, this is typically handled in a separate IP assignment agreement, but referencing it in your founders agreement is good practice.
- Founder Departures: Decide what happens if a founder leaves. Will the company have the right to buy back their shares? At what price? Will unvested equity be forfeited? For example, if a founder is terminated for cause, they might lose all unvested shares. If they leave voluntarily, they may keep vested shares but lose the rest.
- Confidentiality and Non-Compete: Include provisions to protect your business from founders leaving and competing or disclosing sensitive information. Note that non-compete agreements are restricted or unenforceable in some states, such as California, so check local law before including them.
- Dispute Resolution: Specify how disputes will be resolved. Many agreements require mediation or arbitration before litigation. This can save time and money if disagreements arise.
Example: Three founders start a digital marketing agency in Texas. They agree on a 40-30-30 equity split, with a four-year vesting schedule and a one-year cliff. The CEO handles sales, the COO manages client relationships, and the CTO oversees technology. All major decisions require a two-thirds vote. If a founder leaves, the company can buy back their unvested shares at cost. The agreement includes a confidentiality clause and requires disputes to go to mediation first.
Checklist for your founders agreement:
- List all founders and their initial ownership percentages
- Define each founder's role and authority
- Set out a vesting schedule (if using one)
- Include IP assignment language
- Describe how decisions will be made (majority, supermajority, unanimous, etc.)
- Address what happens if a founder leaves (voluntarily or involuntarily)
- Include confidentiality and non-compete provisions if appropriate
- Specify a process for resolving disputes
- Ensure the agreement is consistent with your company's bylaws or operating agreement
- Have all founders sign and date the agreement
State-law caveat: Always check your state's rules on non-competes, buyback rights, and required governance documents. For example, California generally prohibits non-compete clauses, while Delaware allows more flexibility. If you are unsure, consult a qualified attorney familiar with your jurisdiction.
Common Mistakes and How to Avoid Them
Even experienced founders can make mistakes when drafting or maintaining a founders agreement. Here are some of the most common pitfalls, with practical tips for avoiding them:
- Not having a written agreement: Verbal agreements are hard to prove and enforce. Always put your founders agreement in writing, even if you trust your co-founders.
- Ignoring vesting schedules: Without vesting, a founder who leaves early could keep a large stake, making it harder to attract investors or new team members. Use a standard vesting schedule unless there is a strong reason not to.
- Failing to assign IP: If founders do not formally assign their intellectual property to the company, it can create ownership disputes and make fundraising difficult. Use a separate IP assignment agreement if needed, and reference it in your founders agreement.
- Overlooking state-specific requirements: Each state has its own rules for business formation and governance. Failing to comply can result in fines, loss of good standing, or even dissolution. For example, New York requires LLCs to adopt a written operating agreement within 90 days of formation.
- Not updating other documents: Your founders agreement should align with your bylaws, operating agreement, and state filings. Inconsistencies can cause confusion and legal risk. Review all documents together before finalizing.
- Unclear decision-making processes: If your agreement does not spell out how decisions are made, you may face deadlocks or disputes. Be specific about voting thresholds and tie-breakers.
- Not planning for founder departures: Life happens. Make sure you have a clear plan for what happens if a founder leaves, is terminated, or passes away. Include buyback rights and specify how shares will be valued.
- Not keeping agreements up to date: As your business grows, your needs may change. Review and update your founders agreement if you add new founders, change roles, or raise capital.
Practical example: A New York startup did not update its founders agreement after adding a fourth founder. When the company raised its first round of funding, investors found conflicting information about ownership percentages in the agreement and the cap table. This delayed the investment and required costly legal work to fix. Avoid this by updating all documents whenever your ownership structure changes.
Internal Governance: How a Founders Agreement Fits In
Your founders agreement is just one piece of your company's internal governance. Internal governance refers to the rules and processes your business uses to make decisions, manage operations, and resolve disputes. Other key governance documents include:
- Bylaws: For corporations, bylaws set out how the company will be managed, how meetings are held, and how directors and officers are selected. In Delaware and California, bylaws are required but not filed with the state.
- Operating Agreement: For LLCs, this document outlines management structure, voting rights, and profit distributions. In New York, a written operating agreement is required within 90 days of formation.
- Shareholder Agreement: For corporations with multiple shareholders, this agreement covers rights and obligations beyond what is in the bylaws, such as transfer restrictions and buy-sell provisions.
It is critical that your founders agreement does not conflict with these documents. For example, if your bylaws say only the board can approve issuing new shares, but your founders agreement allows any founder to do so, this can create confusion or legal problems. Always review all governance documents together and update them as needed.
Checklist for aligning your governance documents:
- Review all documents for consistency before signing
- Update your founders agreement if you amend your bylaws or operating agreement
- Keep signed copies of all documents in a secure place (digital and physical)
- Communicate changes to all founders and key stakeholders
- Ask your attorney to review for conflicts if you make significant changes
Practical example: A Delaware corporation's founders agreement allowed any founder to hire employees, but the bylaws required board approval. When a founder hired a new team member without board consent, the board challenged the hire and the company had to renegotiate the employment agreement. This could have been avoided by ensuring the founders agreement and bylaws were consistent.
Good governance helps your business run smoothly, attract investors, and avoid disputes. A clear, well-drafted founders agreement is a key part of that process, but it must be kept up to date and consistent with your other documents.
FAQs
Is a founders agreement legally required in the US?
No, a founders agreement is not legally required at the federal or state level. However, it is highly recommended for any business with more than one founder. It helps clarify roles, ownership, and expectations, reducing the risk of disputes. Some states require other documents, such as bylaws or operating agreements, but not a founders agreement itself.
Do I need to file my founders agreement with the state?
No, you do not file your founders agreement with the state. State filings typically include articles of incorporation or organization, registered agent information, and sometimes bylaws or operating agreements. Your founders agreement is an internal document, but it should be consistent with your official filings and governance documents.
What happens if a founder leaves the company?
This depends on what your founders agreement says. Many agreements include a buyback or repurchase clause, allowing the company or remaining founders to buy back the departing founder's shares, often at fair market value or a predetermined price. If there is no agreement, state law or your operating documents may control what happens. For example, in Delaware, the company may have broad discretion if the agreement is silent, but in California, default rules may be less flexible.
Can a founders agreement be changed later?
Yes, founders agreements can be amended if all parties agree. It is common to update the agreement as the business grows, new founders join, or roles change. Make sure to document any changes in writing and have all founders sign the updated agreement. Also update your bylaws, operating agreement, and cap table as needed.
What is the difference between a founders agreement and an operating agreement?
A founders agreement is a contract between the original owners of a business, covering roles, equity, and expectations. An operating agreement (for LLCs) or bylaws (for corporations) are formal governance documents required or recommended by state law. These documents have different purposes but should be consistent with each other. For example, your founders agreement might set out the initial equity split, while your operating agreement covers voting rights and profit distributions.
