How to Choose a Business Partner: 10 Due Diligence and Legal Checks for Startup Founders
A potential business partner can bring customers, technology, expertise, funding or market access that can accelerate your startup.
But before you say “Let’s partner,” take a step back.
A partnership may begin with a conversation and trust, but a good business partnership needs clarity, verification and a proper agreement.
Here are 10 checks every startup founder should consider before entering a partnership.
1. Check Their Background
Start with the basics.
Look at their professional history, businesses, experience, reputation and existing commitments.
Ask: Do I know enough about the person or organisation I am about to work with?
2. Verify What They Are Bringing
“Network”, “customers”, “technology” or “market access” can sound impressive.
But what exactly will they contribute?
Define the contribution in specific, measurable terms rather than relying on broad promises.
3. Check Their Financial Position
If the partnership involves investment, revenue sharing, credit, assets or financial commitments, understand the financial position and obligations of the other party.
For significant partnerships, appropriate financial due diligence can prevent unpleasant surprises later.
4. Look for Conflicts of Interest
Could the partner be working with a competitor?
Do they have other businesses or commitments that could affect the partnership?
Identify potential conflicts before, not after, the relationship begins.
5. Clarify Roles and Responsibilities
Avoid statements such as:
“We will both take care of it.”
Who will actually do what?
Define responsibilities, deliverables, timelines and decision-making authority.
If responsibility is shared, accountability should still be clear.
6. Protect Intellectual Property
Who owns the technology, content, designs, data, processes or intellectual property created during the partnership?
This is particularly important for startups where technology and intellectual property may be among the most valuable assets.
Put ownership and usage rights in writing.
7. Discuss Confidentiality and Data
Partnerships often involve sharing sensitive information—business plans, customer information, pricing, technology or proprietary data.
Agree on what can be shared, with whom, and how information will be protected.
Where personal data is involved, applicable privacy and data-protection obligations should also be considered.
8. Be Clear About the Money
Discuss the uncomfortable questions early:
Who pays for what?
How will revenue be shared?
Who bears losses or additional costs?
When will payments happen?
What happens if the expected business doesn't materialise?
A partnership becomes easier when money is discussed before money becomes a problem.
9. Decide How Disagreements Will Be Handled
Even good partners will disagree.
Decide in advance how major decisions will be made and how unresolved disputes will be handled.
Don't assume that trust today will automatically resolve disagreements tomorrow.
10. Have an Exit Plan
This is one of the most overlooked parts of a partnership.
Ask: What happens if one partner wants to leave?
Define the process for termination, outstanding payments, customer relationships, intellectual property, confidential information and ongoing commitments.
A good partnership agreement should address how the relationship ends—not just how it begins.
The Partnership Checklist
Before signing a partnership agreement, make sure you can clearly answer:
Who? — Who are we partnering with?
Why? — What value does the partnership create?
What? — What exactly will each party contribute?
How? — How will we work and make decisions?
What if? — What happens when things don't go as planned?
How out? — How can either party exit?
If these questions are difficult to answer, you may not be ready to sign the partnership agreement.
Trust Is Important. Clarity Is Essential.
You don't enter a partnership because you distrust someone.
You do due diligence because good relationships deserve good structures.
Before you sign, document the important terms and seek appropriate legal, financial or professional advice for your specific situation.
