Co-founder Agreement Generator
The Ultimate Guide to Co-Founder Agreements: Legal Insights and How to Generate Yours
Launching a startup with co-founders is exciting—but failing to set clear legal expectations can turn that excitement into conflict. As a California e-commerce and corporate lawyer, I’ve seen too many startups unravel due to vague or non-existent agreements between founders.
This guide explains everything you need to know about co-founder agreements, key legal considerations, and how to efficiently draft one using my Co-Founder Agreement Generator.
What is a Co-Founder Agreement?
A Co-Founder Agreement is a legally binding document that outlines the rights, responsibilities, and obligations of each founder in a startup. It sets the foundation for governance, ownership, and operational clarity.
Co-Founder Agreement vs. Other Corporate Documents
- Operating Agreement: Governs LLC operations.
- Bylaws: Internal rules for corporations.
- Shareholders’ Agreement: Addresses shareholder rights.
A Co-Founder Agreement is complementary—it governs personal arrangements between founders before or alongside formal corporate governance documents.
Key Legal Issues Addressed in a Co-Founder Agreement
Roles and Responsibilities
Define who does what. Titles aren’t enough—clarify duties, decision-making authority, and expected time commitments.
Equity Split and Vesting
Avoid “equal split by default” traps. Align equity with contributions and future commitment. Implement vesting schedules to protect against “free rider” founders.
Intellectual Property (IP) Ownership
All IP created for the startup should belong to the company. Clearly assign rights and disclose pre-existing IP.
Decision-Making Protocols
Will decisions require unanimous consent, majority vote, or equity-weighted voting? Define this to prevent deadlocks.
Exit, Termination & Buyout Provisions
Establish what happens if a founder leaves—voluntarily or involuntarily. Address forfeiture, repurchase rights, and fair market valuation.
Confidentiality & Non-Compete Clauses
Protect sensitive information and prevent founders from immediately competing after departure (subject to state enforceability, e.g., California restricts non-competes).
Dispute Resolution & Governing Law
Specify jurisdiction and whether disputes go to court or arbitration.
Step-by-Step: Using the Co-Founder Agreement Generator
My Co-Founder Agreement Generator simplifies drafting by guiding you through essential legal decisions.
1. Company Information
Identify your business structure—even if you haven’t formally incorporated yet.
2. Co-Founder Details
List each founder’s legal name and contact information.
3. Roles and Responsibilities
Assign titles, outline duties, and set expectations for time commitments.
4. Equity Distribution & Vesting
Choose between fixed percentages or dynamic allocation. Select standard, accelerated, or custom vesting schedules.
5. Intellectual Property
Decide whether all IP is assigned to the company or if limitations apply. Disclose pre-existing IP and carve-outs.
6. Exit and Termination Terms
Define procedures for voluntary departures, termination for cause, non-compete terms, and handling a potential company sale.
7. Finalize and Download
Review the live preview, copy the text, or download as PDF. Optionally, schedule a consultation for legal review.
Legal Best Practices When Drafting a Co-Founder Agreement
Customize Thoughtfully
While my generator covers key provisions, ensure that selections reflect your unique business dynamics.
Integrate with Corporate Documents
Once your entity is formed, align this agreement with your Bylaws, Operating Agreement, or Shareholders’ Agreement.
Investor Expectations
Sophisticated investors will review founder agreements to assess:
- Vesting protections
- IP assignments
- Clean cap tables without unresolved founder disputes
Review State Law Nuances
For example, non-compete clauses are unenforceable in California except in narrow situations.
Common Mistakes Founders Make
1. Equal Equity Splits Without Context
Friendship isn’t a business strategy. Allocate based on value and commitment.
2. No Vesting Schedule
Without vesting, a departing founder could walk away with a large equity stake, discouraging future investors.
3. Ignoring IP Assignments
If IP isn’t properly assigned, founders could later claim ownership over core assets.
4. Overly Broad Non-Competes
Unenforceable clauses can create false security. Draft narrowly and in compliance with state law.
5. Failing to Plan for Exits
Departures are inevitable. Without clear terms, they often lead to litigation.

A well-drafted Co-Founder Agreement isn’t just legal paperwork—it’s a roadmap for collaboration, accountability, and protecting what you’re building.
