NDA basics
An NDA is a contract in which one or both parties promise to keep certain information confidential. A good NDA defines what counts as confidential, how the information may be used, how long the obligation lasts, and what exclusions apply.
NDAs do not protect information that is already public, that the receiving party already knew, or that they develop independently without using your confidential information.
Confidentiality concepts
Confidential information usually includes business plans, financial data, customer lists, technical designs, source code, and unreleased products. NDAs typically combine a definition of confidential information with standard carve-outs and a clear permitted use.
Strong NDAs specify how long the obligation runs (often two to five years for general information, longer or indefinite for true trade secrets) and what happens if confidentiality is breached.
Common business and startup use cases
NDAs are most useful before sensitive information is shared, not after. Common scenarios include:
- Pitching strategic investors or angels who are not major VCs
- Sharing technical prototypes, designs, or roadmaps
- Discussing partnerships, acquisitions, or licensing deals
- Hiring contractors who will see private business systems
- Allowing audits of finances, security, or operations
Contractor and freelancer applications
When contractors will see private customer data, internal systems, or unreleased products, an NDA — often built into the contractor agreement — protects the business while clarifying expectations.
Mutual NDAs are common when both parties will exchange sensitive information; one-way NDAs are appropriate when only one side is disclosing.
Limitations of NDAs
An NDA cannot stop someone from competing with you, replace employment or contractor agreements, or magically protect ideas that are already public. Enforcement requires evidence that information was actually confidential and that the obligation was breached.
Many large investors will not sign NDAs at the seed stage. Pushing for one in those situations can stall conversations that should have moved forward.
Frequently asked
- What is the difference between a mutual and a one-way NDA?
- A one-way NDA covers a situation where only one side discloses confidential information. A mutual NDA applies when both sides will share sensitive information.
- How long should an NDA last?
- Typical terms range from two to five years for general confidential information, with longer or indefinite protection for genuine trade secrets.
- Can an NDA stop competition?
- No. NDAs protect confidential information. Non-compete and non-solicitation obligations are separate clauses and are subject to specific legal limits.
- Do I need an NDA before pitching investors?
- Many institutional investors will decline to sign. For early-stage pitches, share thoughtfully rather than relying on an NDA.
