Starting a business with co-founders is an exciting step, but it is also a moment when many US founders make preventable mistakes. Too often, founders rely on informal agreements, handshake deals, or vague emails to set expectations about roles, equity, and decision-making. This can lead to confusion, disputes, and even the collapse of the business if things go wrong. A founders agreement is a practical tool to address these issues upfront. This guide explains when a business should use a founders agreement, what it should include, how it fits with other governance documents, and what to watch out for under US federal and state law. We include practical examples, checklists, and common pitfalls to help you protect your business and your relationships from the beginning.
What Is a Founders Agreement?
A founders agreement is a private contract between the original founders of a business. Its main purpose is to clarify each founder's rights, responsibilities, and expectations. This includes how ownership is divided, how decisions are made, what happens if someone leaves, and how to handle disputes. While not required by federal law, a founders agreement is a best practice for startups and small businesses with more than one founder.
Unlike articles of incorporation, bylaws, or operating agreements, a founders agreement is usually signed before or at the same time as forming the business entity. It is not a public document and is not filed with state agencies. Instead, it is a private roadmap for the founding team, helping to prevent misunderstandings and reduce the risk of costly disputes.
- Key features of a founders agreement:
- Defines each founder's role and responsibilities
- Specifies how equity or ownership is divided
- Establishes decision-making processes
- Addresses what happens if a founder leaves (exit or vesting provisions)
- Includes confidentiality and intellectual property (IP) terms
- Provides a process for resolving disputes
Founders agreements are not a substitute for required state filings or entity documents. Instead, they supplement those documents by addressing issues unique to the founding team. They can also help demonstrate to investors, banks, or partners that the business is well organized and serious about governance.
When Should a Startup Use a Founders Agreement?
The best time to use a founders agreement is before the business formally launches or as soon as the idea becomes a real project. This is usually before registering a company, applying for an EIN with the IRS, or filing with the Secretary of State. However, if you have already started operating without one, it is not too late. Founders can sign an agreement at any stage, but earlier is better to avoid disputes and confusion.
Some common situations where a founders agreement is especially useful include:
- Two or more people are working together on a new business idea
- Founders are contributing different types of value (capital, skills, intellectual property, industry contacts)
- You plan to raise outside investment or apply for business loans
- There is a risk of founders leaving, joining, or changing roles
- Founders want to avoid future disputes about ownership, contributions, or decision-making
For example, imagine three friends start a software company. One brings coding skills, one brings marketing expertise, and one provides the initial funding. Without a founders agreement, there may be confusion later about who owns what percentage, who gets to make key decisions, or what happens if one person wants to leave. A written agreement can address all of these issues up front, reducing the risk of misunderstandings.
It is important to note that while federal law does not require a founders agreement, state rules may affect how your business is formed and governed. For example, some states require operating agreements for LLCs or bylaws for corporations, but these are different documents. A founders agreement is typically a private contract between the individuals, not filed with the state. However, the terms of your founders agreement should not conflict with your operating agreement or bylaws, as this can create legal uncertainty.
In states like Delaware, California, and New York, investors and accelerators often expect to see a founders agreement in place before funding or joining a program. Some state laws may also affect the enforceability of certain clauses, such as non-compete or non-solicit provisions. Always check local rules or consult with an attorney familiar with your state.
What Should Be Included in a Founders Agreement?
Every founders agreement should be tailored to the specific business and founders involved. However, there are several common sections that most agreements cover:
- Equity Split: How will ownership be divided among founders? Will there be vesting schedules or cliffs? For example, a typical arrangement might be 40% for the technical founder, 40% for the business founder, and 20% for the marketing founder, with a four-year vesting schedule and a one-year cliff to protect the business if someone leaves early.
- Roles and Responsibilities: What is each founder expected to do? Who is CEO, CTO, or in charge of sales? This section should be as specific as possible to avoid overlap or confusion.
- Decision-Making: How will major business decisions be made? Will some decisions require unanimous consent? For example, you might require unanimous agreement for selling the company, but allow majority vote for hiring employees.
- Capital Contributions: Are founders putting in money, assets, or intellectual property? How is this valued? For example, if one founder contributes $50,000 in cash and another contributes a patent, the agreement should specify how these contributions are valued and how they affect equity.
- Vesting and Exit Provisions: What happens if a founder leaves early? Will they keep all their equity? Vesting provisions help protect the business by ensuring that founders earn their equity over time.
- IP Assignment: Will founders assign inventions or code to the company? This is especially important for tech startups, as investors will want to see that the company owns all core intellectual property.
- Confidentiality: How will sensitive business information be protected? This section should require founders to keep business secrets confidential, even after leaving the company.
- Dispute Resolution: How will disagreements be handled? Mediation, arbitration, or court? Some agreements specify a particular state law or venue for resolving disputes.
- Non-Compete and Non-Solicit: Are there restrictions on founders starting competing businesses or poaching clients? Note that some states, like California, limit the enforceability of non-compete clauses.
Here is a practical checklist for founders drafting an agreement:
- List all founders and their contact details
- Describe each founder's role and expected contributions
- Specify equity percentages and any vesting terms
- Set out decision-making rules (majority, unanimous, tie-breakers)
- Include IP assignment and confidentiality clauses
- Address what happens if a founder leaves or wants to sell their stake
- Include a process for resolving disputes
- Have all founders sign and date the agreement
Many founders use templates as a starting point, but it is wise to have the agreement reviewed by an attorney familiar with startup law and state-specific issues. This can help avoid gaps or terms that do not match your business goals or local legal requirements.
For example, in Texas, courts may enforce non-compete clauses if they are reasonable in scope and duration, while in California, such clauses are generally unenforceable except in limited circumstances. In Delaware, vesting and buyback provisions are common and often expected by investors. These state-specific nuances can have a significant impact on your agreement's effectiveness.
How Does a Founders Agreement Fit With Other Business Documents?
A founders agreement is just one part of your business's legal foundation. It works alongside other documents, but does not replace them. Here is how it fits with common US business documents:
- Articles of Incorporation (or Organization): Filed with the Secretary of State to create a corporation or LLC. This is a public document and usually does not cover founder relationships.
- Bylaws (Corporation) or Operating Agreement (LLC): These set out how the company is run, voting rights, meetings, and other governance issues. Some states require these, and they may overlap with the founders agreement. However, bylaws and operating agreements are usually for the company as a whole, not just the founders.
- Shareholder Agreements: For corporations, these may cover additional rights for shareholders, including founders and investors.
- Employment or Contractor Agreements: If founders are also employees or contractors, these documents cover their day-to-day work, pay, and benefits.
- IP Assignment Agreements: Sometimes used to formally transfer inventions, code, or other IP from founders to the company.
It is important to keep these documents consistent. For example, if your founders agreement says one thing about equity or decision-making, but your operating agreement says another, this can create confusion or disputes. When raising investment, investors will often review all these documents to make sure they match and that the business is well organized.
Federal agencies like the IRS may require certain documents when applying for an EIN or tax status, but do not require a founders agreement. State agencies, such as the Delaware Division of Corporations or your local Secretary of State, will have their own filing requirements for entity formation. The founders agreement is usually kept private among the founders and not filed with government agencies.
Here is a practical example: Suppose your founders agreement says that all major decisions require unanimous consent, but your LLC operating agreement says that a majority vote is enough. If a dispute arises, it may not be clear which rule applies. This can lead to legal uncertainty and make it harder to attract investors or resolve conflicts. To avoid this, review all your business documents together and update them as needed to ensure consistency.
Another example: In some states, like New York, LLCs are required to have a written operating agreement, even if there is only one member. While a founders agreement is not a substitute for an operating agreement, it can help ensure that the founders' intentions are reflected in the company's official documents.
Common Mistakes and How to Avoid Them
Many founders make avoidable mistakes when it comes to founders agreements. Here are some of the most common, and tips for avoiding them:
- Not having a written agreement: Verbal agreements or informal emails are hard to enforce and often lead to misunderstandings.
- Delaying the agreement: Waiting until after the business is up and running can make it harder to agree on terms, especially if the business is already making money or attracting investors.
- Ignoring vesting provisions: Without vesting, a founder who leaves early may keep all their equity, which can hurt the business and remaining founders.
- Overlooking IP assignment: If founders do not assign their IP to the company, there can be disputes over ownership of code, inventions, or branding.
- Using generic templates without review: Templates can be a good starting point, but may not fit your specific business, state laws, or industry requirements.
- Failing to update agreements: As the business grows, founders may join or leave, or the business may pivot. The agreement should be reviewed and updated as needed.
- Conflicting documents: Having a founders agreement that conflicts with your operating agreement or bylaws can create legal uncertainty and make it harder to resolve disputes.
- Not considering state law: Some clauses, such as non-compete or non-solicit provisions, may be unenforceable or limited in certain states. Always check local rules before including these terms.
To avoid these pitfalls, make it a priority to discuss and document key issues with your co-founders early. Consider having a neutral third party, such as an attorney, facilitate the conversation or review the final agreement. Keep signed copies in a safe place and revisit the agreement as your business evolves.
Here is a practical scenario: Two founders in Florida start a digital marketing agency. They agree informally that each will own 50 percent of the business. Six months later, one founder wants to leave and start a competing agency. Without a written agreement, it is unclear whether the departing founder can keep their full equity or use client lists. A founders agreement with clear vesting, non-solicit, and confidentiality clauses could have addressed these issues and protected the business.
FAQs
Is a founders agreement legally binding?
Yes, a properly drafted and signed founders agreement is generally legally binding as a contract between the founders. However, it must meet standard contract requirements under state law, such as offer, acceptance, and consideration. Some terms, like non-compete clauses, may be limited or unenforceable in certain states. It is important to check state-specific rules and have the agreement reviewed if you have questions about enforceability.
Can a founders agreement be changed after it is signed?
Yes, founders can amend their agreement by mutual consent. It is common to update the agreement if a new founder joins, someone leaves, or the business pivots. Any changes should be made in writing and signed by all founders to avoid confusion.
Do I need a founders agreement if I am a solo founder?
Solo founders typically do not need a founders agreement, since there are no co-founders to contract with. However, solo founders should still have other key documents, such as an operating agreement (for LLCs), bylaws (for corporations), and IP assignment agreements if working with contractors or collaborators.
How does a founders agreement affect raising investment?
Investors often want to see that founders have a clear agreement in place, especially regarding equity, vesting, and IP ownership. A well-drafted founders agreement can make your business more attractive to investors by showing that key risks have been addressed. However, investors may require changes to the agreement as part of their investment terms.
Is a founders agreement required to register a business with the state?
No, a founders agreement is not required to register a business entity with your state. However, some states require other documents, such as articles of incorporation or operating agreements, depending on your entity type. The founders agreement is a private contract among the founders and is not filed with state agencies.
