Non-Disclosure Agreement (NDA): Protecting Your Startup’s Confidential Information
• 11 Sep 25
“A secret isn’t a secret once it’s shared - unless you have it in writing.” Matt Glynn - Managing Director GLS Group
Introduction
In the fast-paced startup world, you’ll often need to share sensitive information - from product designs to marketing strategies - with employees, partners, investors, or contractors.
Without legal protection, that information could end up in the wrong hands. A non-disclosure agreement (NDA), sometimes called a confidentiality agreement, ensures your confidential information stays exactly that - confidential.

What Is a Non-Disclosure Agreement (NDA)?
An NDA is a legally binding contract that sets out what information is confidential, how it can be used, and what happens if it’s disclosed without permission.
NDAs can be:
◼️Unilateral - One party shares confidential information with another.
◼️Mutual - Both parties share and protect each other’s confidential information.
Q: Is an NDA legally binding?
A: Yes - as long as it meets contract law requirements and is properly executed.
Why an NDA Matters for Startups
Protects Competitive Advantage
◼️Keeps trade secrets, algorithms, and product designs from competitors.
Builds Trust with Partners & Investors
◼️Shows you take confidentiality seriously.
Prevents IP Leakage
◼️Ensures proprietary assets stay within the company.
Required by Some Partners
◼️Large companies often require NDAs before sharing sensitive information.

Key Clauses in an NDA
When drafting an NDA, include:
Definition of Confidential Information
◼️Clearly specify what is (and isn’t) confidential.
Purpose Limitation
◼️Restrict use of the information to specific purposes only.
Exclusions
◼️Information already public, independently developed, or obtained lawfully from others.
Obligations of Receiving Party
◼️How information must be protected (security measures, no sharing, etc.).
Duration
◼️How long the confidentiality obligations last.
Remedies for Breach
◼️Injunctions, damages, and other enforcement options.
Risks of Not Having an NDA
Without an NDA, you risk:
◼️Loss of trade secrets through unauthorised disclosure.
◼️Weakened IP protection in legal disputes.
◼️Investor hesitation if confidentiality measures are lax.
◼️Brand damage if sensitive information is leaked.
Q: Can an NDA protect ideas?
A: Not directly - but it protects the confidential information in which the idea is expressed.
Case Study: The Investor Leak
Q: Can an NDA be verbal?
A: In theory, yes - but written NDAs are far stronger and easier to enforce.
Q: How long should an NDA last?
A: Commonly 2-5 years, though some obligations (like trade secrets) may last indefinitely.
Q: Do I need separate NDAs for each partner?
A: Often yes - though master NDAs can cover multiple transactions.
Q: Can employees be covered by the same NDA as contractors?
A: Best practice is to include confidentiality clauses in employment contracts and have contractors sign standalone NDAs.

Observations and Tips
- Use NDAs Before Sharing Sensitive Information: Execute NDAs before disclosing confidential business, product, or financial information.
- Define Confidential Information Clearly: Specify what information is protected and what falls outside the NDA scope.
- Tailor NDAs to the Relationship: Investor, employee, vendor, and partnership NDAs may require different protections.
- Include Proper Use Restrictions: Limit how confidential information may be accessed, used, or disclosed.
- Set Clear Duration & Survival Terms: Define confidentiality periods and obligations that survive termination.
- Protect Intellectual Property Rights: Ensure disclosures do not unintentionally transfer ownership or usage rights.
- Address Return & Destruction Obligations: Require confidential materials to be returned or deleted after engagement ends.
- Use Enforceable Jurisdiction Clauses: Specify governing law and dispute resolution mechanisms carefully.
- Maintain Records of Disclosures: Track shared documents, recipients, and executed agreements systematically.
- Avoid Over-Reliance on Verbal Understandings: Unwritten confidentiality expectations are difficult to enforce legally.
- Prevent Excessive or One-Sided Restrictions: Overbroad NDAs may become commercially impractical or legally unenforceable.
- Implement Confidentiality Processes Internally: Strong internal controls are essential alongside contractual protections.
