Business Transactions

Starting a business with co-founders is exciting. You're aligned on vision, passionate about the idea, and ready to build something great together. But without a founder agreement, you're setting yourself up for conflict, confusion, and potentially catastrophic disputes that can destroy your company before it even launches.

A founder agreement typically documents equity, vesting, roles, decision rights, IP ownership, founder departures, and dispute mechanics before the company raises money or a founder leaves. There is no one-size-fits-all version: the agreement should fit the entity, cap table, governing law, and the founders' actual working relationship.

What is a Founder Agreement?

A founder agreement is a legal contract between co-founders that defines ownership, roles, responsibilities, decision-making authority, and what happens in various scenarios (departure, disagreement, acquisition, etc.). It's the foundational document that governs your relationship and protects everyone's interests. Think of it as a prenup for your business.

Why You Need One Before Launch

Many founders delay a written agreement because they expect to 'figure it out later' or trust the relationship to carry them through. The risk is not that every informal understanding is automatically unenforceable; it is that oral or incomplete arrangements can be hard to prove and may not satisfy applicable writing requirements. Investors and acquirers also commonly expect clean ownership, vesting, IP, and governance records. Documenting the arrangement while the founders are aligned is usually easier than trying to reconstruct it after a conflict.

Need a founder agreement built around your actual cap table and roles?

Key Components of a Founder Agreement

Equity Allocation: How is ownership divided among founders? Is it equal or weighted based on contribution, experience, or other factors? Equity splits should reflect each founder's expected contribution and value to the company. Clearly document the rationale so everyone understands and agrees.

Vesting Schedules

After agreeing on equity splits, founders commonly use vesting or repurchase rights so ownership reflects continued contribution. A four-year schedule with a one-year cliff is common, but it is not universal and should fit the company and the founders' arrangement. If a founder leaves early, properly drafted vesting and repurchase terms can keep unearned equity from remaining outstanding. Investors also commonly review these terms as part of the cap table and governance record.

Roles and Responsibilities

Define each founder's role, responsibilities, and decision-making authority: Who is CEO, CTO, COO, etc.? What are each founder's primary duties and areas of ownership? How are major decisions made (unanimous, majority, CEO authority)? What happens if a founder isn't meeting responsibilities? Clear roles prevent overlap, confusion, and conflict over who's responsible for what.

Time Commitment

Clarify expectations around time commitment: Is this full-time or part-time for each founder? What happens if someone wants to keep their day job initially? Are there minimum hour requirements? Mismatched time commitments destroy startups. If one founder is full-time and another is part-time, address how that affects equity, decision-making, and expectations.

Intellectual Property Assignment

The company should receive a clear assignment of the intellectual property it is intended to own. The agreement should address IP created before and during the company's existence, identify any prior-employer or third-party obligations, and define which work product transfers to the company. Ambiguous ownership can complicate fundraising, licensing, or an acquisition.

Compensation and Expenses

How will founders be compensated? Are you taking salaries or deferring compensation? How are business expenses handled? Who can make purchases and within what limits? Document compensation expectations to avoid resentment when one founder draws a salary while others don't.

Decision-Making and Governance

How will major decisions be made? Define voting rights and decision-making processes: What requires unanimous founder approval? What can be decided by majority vote? What authority does the CEO have independently? How are tie-breaking situations resolved? Clear governance structures prevent deadlock and conflict.

Departure and Termination

What happens if a founder wants to leave or needs to be removed? Address: Voluntary departure process and equity treatment. Involuntary termination for cause (and how 'cause' is defined). Buyback rights for unvested equity. Non-compete and non-solicitation obligations post-departure. Having these terms in place before conflict arises makes difficult transitions smoother.

Dispute Resolution

How will you handle disagreements that can't be resolved internally? Options include: Mediation requirements before litigation. Binding arbitration clauses. Designated advisors or board members to help resolve disputes. A defined dispute-resolution process can reduce uncertainty, cost, and disruption if a disagreement cannot be resolved internally.

Confidentiality and Restrictive Covenants

Protect the company with appropriately tailored confidentiality obligations and, where lawful and useful, non-solicitation or other restrictive covenants. The enforceability of non-compete and non-solicitation provisions varies materially by state, the relationship, the scope of the restriction, and current law. Counsel should evaluate whether a restriction is permitted and narrowly tailored rather than treating it as boilerplate.

Founder Shares and Capitalization

Document the initial equity structure: How many shares does each founder receive? What type of shares (common, preferred)? What's the total number of authorized shares? How much equity is reserved for employee stock option pool? Having this clearly documented is essential for future fundraising and equity grants.

Amendment and Modification

Include provisions for how the agreement can be amended: Typically requires unanimous founder consent. Should be in writing and signed by all parties. May need board or shareholder approval depending on corporate structure. Flexibility to modify the agreement as the company evolves is important.

Common Mistakes to Avoid

Delaying the agreement until after launch or fundraising. Assuming 'we'll figure it out' is an acceptable approach. Creating overly simple agreements that don't address key scenarios. Copying templates without customizing for your specific situation. Not having legal counsel review the agreement. Failing to implement vesting schedules. Avoid these mistakes. A strong founder agreement is an investment in your company's future.

When to Create Your Founder Agreement

Ideally, before you incorporate. At the latest, before you start building the product, raising money, or hiring employees. The earlier, the better. Don't wait until you're facing problems to address them.

Working with Legal Counsel

While templates are a starting point, work with an experienced startup attorney to: Customize the agreement to your specific situation and state laws. Ensure all necessary provisions are included. Avoid unenforceable or problematic terms. Align the founder agreement with your corporate structure and other legal documents. Early legal review can be less disruptive than trying to unwind inconsistent ownership, IP, or governance expectations after a dispute.
