Founders Agreement: What To Review Before Signing

Starting a business with co-founders is exciting, but it also brings legal and practical challenges that many founders underestimate. Too often, US startups sign a founders agreement without fully understanding what it covers, what is missing, or how state rules might impact their business. Common mistakes include unclear equity splits, missing intellectual property (IP) assignments, or failing to address what happens if a founder leaves or wants out. This guide explains what a founders agreement is, why it matters, and what every US startup should check before signing. We cover federal and state issues, key terms, practical examples, and step-by-step checklists to help founders avoid costly mistakes and set clear expectations from day one.

What Is a Founders Agreement?

A founders agreement is a private contract between the initial owners of a startup or small business. It sets out the rights, responsibilities, and expectations of each founder. While not always legally required, a well-drafted founders agreement can help prevent disputes, clarify ownership, and provide a roadmap for decision-making and exits.

In the US, a founders agreement is usually signed before or soon after forming a legal entity, such as a corporation or LLC. It is different from the company's bylaws, operating agreement, or shareholder agreement, which are official governance documents filed or adopted by the business entity itself. The founders agreement is a private contract among the founders, but it should be consistent with the company's official documents and state law.

Key reasons to have a founders agreement include:

• Clarifying each founder's ownership percentage and contributions
• Setting expectations for roles, responsibilities, and time commitments
• Establishing rules for decision-making and resolving disagreements
• Addressing what happens if a founder leaves or wants to sell their stake
• Assigning intellectual property created before and during the business

Without a clear agreement, founders risk misunderstandings, expensive disputes, and problems with investors or future hires. While verbal agreements or handshake deals are common, they rarely hold up if things go wrong. For example, if two friends start a tech company and one leaves after six months, a lack of written agreement can lead to arguments over who owns the code or whether the departing founder keeps their shares.

Key Terms to Include in a US Founders Agreement

Every founders agreement should be tailored to the business and the founders' goals. However, there are several core terms that most US startups should address. Here is a checklist of key provisions to consider, along with practical examples and state law caveats:

• Equity Ownership: Specify each founder's percentage of ownership, how it was calculated, and whether it is subject to vesting. For example, if one founder brings an early prototype and another brings capital, the split might be 60/40. Document the rationale to avoid future disputes.
• Vesting Schedule: Define if and how equity vests over time or based on milestones. This protects the company if a founder leaves early. A common approach is a four-year vesting schedule with a one-year cliff, meaning no equity vests until the founder has stayed for a year. If a founder leaves after 18 months, only a portion of their shares are vested. Note that vesting terms can affect tax filings, such as the IRS 83(b) election.
• Roles and Responsibilities: Outline each founder's expected duties, titles, and time commitments. For example, one founder may be CEO responsible for fundraising, while another is CTO in charge of product development. Clarify whether founders are expected to work full-time or part-time.
• Decision-Making: Set rules for major business decisions, voting thresholds, and tie-breakers. For instance, you might require unanimous consent for selling the company, but a majority vote for hiring employees. Consider what happens in a deadlock situation.
• Intellectual Property (IP) Assignment: Ensure all founders assign relevant IP (such as code, designs, or inventions) to the company. If a founder developed software before the company was formed, the agreement should state that this IP is now owned by the business. Failing to do this can cause problems with investors or acquirers later.
• Confidentiality and Non-Compete: Include clauses to protect business secrets and restrict founders from competing, as allowed by state law. For example, California generally prohibits non-compete clauses, while Texas allows them if they are reasonable in scope and duration. Always check your state's rules before including these terms.
• Founder Departure and Buyout: Explain what happens if a founder leaves, including buyout rights, valuation methods, and any restrictions on selling shares. For example, the agreement might state that the company has the right to buy back a departing founder's shares at fair market value, as determined by an independent appraiser.
• Dispute Resolution: Decide how disputes will be handled (for example, mediation or arbitration). This can help avoid expensive court battles. Specify the governing law and jurisdiction, which is especially important if founders live in different states.
• Amendment Process: Describe how the agreement can be changed in the future. For example, you might require unanimous consent to amend key terms.

Some states have specific rules on non-compete clauses or buy-sell arrangements, so it is important to check local law. For example, California generally restricts non-compete agreements, while other states may allow them under certain conditions. If your company is incorporated in Delaware but operates in New York, you may need to consider the rules in both states.

Practical example: Three founders in Florida agree to a 40/40/20 equity split, with the minority founder contributing less capital but unique industry contacts. Their agreement includes a three-year vesting schedule and a buyout clause if any founder leaves. They check Florida law to ensure their non-solicit clause is enforceable, since Florida courts often uphold reasonable non-solicit agreements but are stricter on non-competes.

Federal and State Rules Affecting Founders Agreements

While there is no federal law that requires or governs founders agreements, several federal rules and agencies are relevant to US startups:

• IRS (Internal Revenue Service): The IRS requires businesses to obtain an EIN (Employer Identification Number) and report ownership for tax purposes. Equity splits and vesting can have tax consequences, such as the need for an 83(b) election if restricted stock is issued. For example, if you grant restricted stock with a four-year vesting schedule, filing an 83(b) election within 30 days can help founders pay taxes on the value at grant, rather than at vesting, which can save money if the company grows quickly.
• SBA (Small Business Administration): The SBA provides guidance on choosing a business structure and the importance of clear founder documentation. Their resources can help you understand whether an LLC, C corporation, or S corporation is best for your goals.

At the state level, rules can vary significantly. For example:

• Business Structure: The process for forming a corporation or LLC, and the required governance documents, are set by state law. For example, Delaware is popular for startups due to its flexible corporate law and business-friendly courts, but each state has its own requirements. If you form your company in Delaware but operate in California, you may need to register as a foreign entity in California and comply with both states' rules.
• Filing Requirements: Some states require the filing of certain agreements or disclosures with the Secretary of State or Division of Corporations. For example, New York requires LLCs to publish a notice of formation in local newspapers, while Delaware does not have this requirement.
• Non-Compete and Non-Solicit Clauses: States like California, Oklahoma, and North Dakota generally prohibit non-compete clauses, while others allow them with restrictions. Texas and Florida, for example, allow non-competes if they are reasonable in time, geography, and scope. Always check the law in your state before including these terms.
• Buyout and Transfer Restrictions: State law may affect how and when founders can transfer or sell their ownership interests. Some states require that certain transfers be approved by the company or other founders, especially in closely held corporations or LLCs.

It is important to ensure that your founders agreement does not conflict with state law or your company's official formation documents. For example, if your operating agreement or bylaws require a supermajority vote for major decisions, your founders agreement should not set a lower threshold. Consulting with a qualified attorney or legal service provider familiar with your state's rules is a smart step before signing.

Example: A startup incorporated in Delaware but operating in Illinois includes a non-compete clause in its founders agreement. The founders later learn that Illinois law recently changed to limit enforceability of non-competes for employees earning less than a certain amount. They revise their agreement to comply with Illinois law, which applies to their business operations.

Common Mistakes and How to Avoid Them

Many founders make avoidable mistakes when drafting or signing a founders agreement. Here are some of the most common pitfalls, with practical examples and ways to avoid them:

• Unclear or Unequal Equity Splits: Failing to document how equity is divided, or agreeing to an even split without considering contributions, can cause resentment and disputes. For example, if two founders split equity 50/50 but one works full-time and the other part-time, disagreements may arise. Use a clear formula and document it in writing, including any rationale for unequal splits.
• No Vesting Schedule: If equity vests immediately, a founder who leaves early could walk away with a large stake. For example, a founder who quits after three months might still own 30 percent of the company. A standard four-year vesting schedule with a one-year cliff is common for startups and can help protect the business.
• Missing IP Assignment: If founders do not assign their IP to the company, the business may not own key assets. For example, if a founder develops software or branding before the company is formed, investors may require proof that the company owns these assets. Include a clear IP assignment clause and ensure all founders sign it.
• Ignoring State Law: Using a template from another state or country can lead to unenforceable terms. For example, a non-compete clause valid in Texas may be void in California. Always check your state's rules on non-competes, buyouts, and required filings.
• No Plan for Founder Departures: Failing to address what happens if a founder leaves, dies, or is terminated can leave the business in limbo. For example, if a founder dies and their shares pass to a family member with no business experience, this can disrupt operations. Include clear buyout and transfer provisions.
• Not Updating the Agreement: As the business grows, roles and contributions may change. Review and update your founders agreement as needed, especially before raising capital, bringing in new partners, or expanding to new states.
• Overlooking Tax and Securities Issues: Equity grants can trigger tax or securities law issues. For example, issuing stock without proper documentation can lead to IRS penalties or state securities law violations. Consult with a tax advisor or attorney before finalizing the agreement.

Taking the time to address these issues early can save significant time, money, and stress down the road. For instance, a New York-based startup avoided a costly dispute by updating their agreement before a funding round, ensuring all IP was assigned and equity splits reflected current contributions.

Checklist: What to Review Before Signing a Founders Agreement

Before you sign a founders agreement, run through this practical checklist to help avoid common oversights:

• Have all founders reviewed and agreed to the equity split and vesting terms? Document the rationale for any unequal splits.
• Are roles, responsibilities, and time commitments clearly described for each founder? Specify full-time or part-time expectations.
• Does the agreement include an IP assignment for all relevant work, including anything created before the company was formed?
• Have you checked your state's rules on non-compete, non-solicit, and buyout clauses? Adjust terms as needed for your state.
• Are there clear procedures for decision-making, voting, and resolving deadlocks? Specify what happens if founders disagree.
• Is there a process for handling founder departures, including buyout terms, valuation methods, and approval for share transfers?
• Does the agreement align with your company's bylaws, operating agreement, or other governance documents? Avoid conflicting terms.
• Have you considered tax implications, such as the need for an IRS 83(b) election if equity is subject to vesting?
• Is there a clear process for amending the agreement in the future? Specify whether unanimous or majority consent is needed.
• Have all founders had the chance to seek independent legal or tax advice? Encourage founders to consult their own advisors.
• Are all signatures, dates, and witness requirements met? Store signed copies securely, using digital signature platforms if possible.

Practical tip: Many founders use cloud storage or a secure company drive to keep all signed agreements and related documents accessible. This makes it easier to share with investors, attorneys, or new team members as the business grows.

Example: A SaaS startup in Colorado used this checklist before signing their founders agreement. They discovered their initial non-compete clause would not be enforceable under Colorado's new law, so they replaced it with a non-solicit clause and a strong confidentiality agreement. This helped them avoid legal issues and close a funding round smoothly.

FAQs

Is a founders agreement legally required in the US?

No federal or state law requires a founders agreement, but it is strongly recommended for any business with multiple founders. It helps prevent disputes and clarifies expectations. Some investors may require one before providing funding.

How is a founders agreement different from an operating agreement or bylaws?

A founders agreement is a private contract among the founders, usually signed before or alongside forming the business entity. An operating agreement (for LLCs) or bylaws (for corporations) are official governance documents required or recommended by state law and adopted by the company itself. The founders agreement should be consistent with these documents but serves a different purpose.

Can we use a template founders agreement from another state?

Using a template from another state can be risky. State laws on non-competes, buyouts, and other terms vary widely. It is important to tailor your agreement to your state's rules and your business's needs. For example, a template from Delaware may not comply with requirements in California or New York.

What happens if a founder leaves before their equity is fully vested?

If the agreement includes a vesting schedule, the departing founder typically keeps only the vested portion of their equity. The unvested shares may be repurchased by the company or redistributed among remaining founders, depending on the agreement's terms. For example, if a founder leaves after 18 months on a four-year vesting schedule, only a portion of their shares are vested and the rest return to the company.

Do we need to file the founders agreement with the state?

In most states, the founders agreement is a private contract and does not need to be filed with the Secretary of State or Division of Corporations. However, some related documents, such as the company's operating agreement or bylaws, may need to be filed or kept on record depending on the state and entity type. Always check your state's requirements for your business structure.
