Founders’ Guide to Partnership Agreements: Don’t Launch Without One

Launching a company with a co-founder? Working with another startup to jointly build something?

Launching a company with a co-founder? Working with another startup to jointly build something? You need a Partnership Agreement - a roadmap for how the relationship works, how profits are shared, and how problems get solved.

What Is a Partnership Agreement?

A Partnership Agreement sets the rules for how two or more people or businesses will collaborate. Even if you're not forming a legal partnership entity (like a GP or LP), you may still want to define terms clearly in writing.

Key Clauses Every Founder Should Include

1. Ownership and Contributions

Spell out each party’s initial investment - cash, IP, equipment, or sweat equity—and how ownership will be divided.

2. Decision-Making

Who makes what decisions? Can one partner bind the company to a deal? Define voting thresholds and tie-breaker mechanisms.

3. Profit and Loss Allocation

How will profits be distributed (or losses shared)? Equal split? Based on ownership? Spell it out.

4. Roles and Responsibilities

Clarify who’s doing what. This avoids duplication, confusion, or finger-pointing down the road.

5. Dispute Resolution

Agree upfront how to handle conflicts - mediation, arbitration, or court? The clearer the plan, the less likely you’ll need it.

6. Exit Terms

What if a partner wants out? Can they sell their share? To whom? Can the other partner buy them out?

Mistakes to Avoid

  • Not having one at all
  • Using a template without tailoring it
  • Not updating the agreement as the business grows
  • Failing to address how to dissolve the partnership

Final Thoughts

Partnerships can be incredibly rewarding - or incredibly messy. A well-drafted agreement creates accountability, trust, and a plan for the unknown. We help co-founders and startup partners set terms that reflect their vision and avoid future friction.

Terms of Service: Why Your Startup Needs Them—Now

If you run a website, app, or platform, your Terms of Service (TOS) are more than just boilerplate - they’re your shield. They limit your liability, set ground rules for users, and give you power to enforce your policies. Skip this, and you open the door to chaos.

Memorandums of Understanding (MOUs): Clarity Without Commitment

In early startup partnerships or exploratory projects, you might not be ready for a full contract - but you still need alignment. A Memorandum of Understanding (MOU) provides a way to set expectations without creating binding obligations.

Letters of Intent (LOIs): What Founders Need to Know Before the Deal

Startups often move fast - but when you're courting investors, buyers, or major customers, you need to slow down just long enough to sign a Letter of Intent (LOI). It’s not a binding contract (usually), but it lays the groundwork for one - and sets the tone for the entire deal.
