Knowing what an NDA is one thing. Knowing when to use one is what actually protects your business. Many owners either over-use NDAs (creating friction in relationships where they aren't needed) or under-use them (leaving genuine vulnerabilities unprotected). Here are the seven situations where an NDA is genuinely the right tool.
1. Sharing a Business Idea With a Potential Co-Founder
Before you bring someone into the founding team, you need to share your vision, strategy, financial projections, and often your core proprietary concept. These conversations should happen under the protection of a mutual NDA, signed before any substantive discussion begins.
Once someone formally joins as a co-founder, a partnership agreement or shareholders' agreement takes over confidentiality duties. But in the exploratory phase — when you're evaluating whether to build something together — an NDA is exactly the right instrument.
Present the NDA before the substantive conversation begins. A serious candidate will expect it and respect you for having it ready.
2. Hiring a Contractor, Freelancer, or Consultant
Outside parties brought in to do work for your business routinely access client data, internal pricing, proprietary systems, and strategic plans. A one-way NDA — signed before the engagement begins — sets clear expectations and creates legal obligations around that access.
Many business owners assume a service agreement covers confidentiality. It only does if it includes an explicit confidentiality clause. Review your service contracts; if the clause isn't there, add it or execute a separate NDA.
3. Onboarding a New Employee
Employees naturally gain access to information that could harm your business if it reached a competitor — client lists, pricing structures, business strategy, financial data. A confidentiality agreement (or a confidentiality clause within the employment agreement) establishes that these obligations exist during and after employment.
In technology, professional services, healthcare, and finance, this is standard practice. Omitting it is increasingly uncommon and increasingly risky in competitive talent markets.
4. Moving Into Due Diligence With an Investor
Early pitch meetings with institutional investors rarely call for NDAs — many VCs won't sign them at the initial pitch stage because they see hundreds of similar pitches and can't risk being locked out of an entire category. Demanding one before a first meeting can signal naivety.
However, when a serious investor moves into due diligence and begins reviewing your detailed financial models, proprietary technology, customer contracts, or competitive intelligence, an NDA becomes appropriate and expected. The same applies when pitching to angel investors, corporate venture arms, or strategic acquirers, where NDAs before substantive conversation are more commonly accepted.
5. Evaluating a Business Partnership or Joint Venture
Two companies exploring whether to work together typically share significant amounts of sensitive information — financials, client bases, strategic roadmaps, operational capabilities. A mutual NDA before these conversations begin protects both parties if the partnership doesn't materialize and ensures that information shared in good faith can't be used against you later.
6. Licensing Your Intellectual Property
Whether you're licensing software, a proprietary method, a brand, or patented technology, both the licensor and licensee typically share sensitive information during negotiation. The licensor shares technical details about the IP; the licensee may share business plans or financial projections. A mutual NDA covers the evaluation phase, while the license agreement itself should include strong confidentiality provisions for the ongoing relationship.
7. Sharing Product Specifications With a Manufacturer
If you've developed a product and need a manufacturer to produce it, your design files, specifications, material choices, and production requirements are among your most valuable proprietary assets. An NDA before sharing any of this is essential — particularly with overseas manufacturers, where IP theft through unauthorized use of your specifications is a well-documented risk.
Note that NDA enforceability varies significantly across international borders. For overseas manufacturing relationships, work with an attorney experienced in international commercial law to ensure your protections are genuinely effective in the relevant jurisdiction.
When You Probably Don't Need an NDA
- General networking conversations — Talking broadly about your business at an event or in an introductory call doesn't require an NDA.
- Relationships already covered by other agreements — If confidentiality is already in a master services agreement or employment contract, a separate NDA may be redundant.
- Information that's already public — You can't create confidentiality obligations around publicly available information.
- Early customer conversations — Requiring a prospect to sign an NDA before learning what your product does creates unnecessary friction and may signal that your product isn't market-ready.
The Underlying Principle
Use an NDA when sharing information with the wrong party could meaningfully harm your business, and when the relationship hasn't yet established other forms of contractual protection. In those situations, an NDA isn't a sign of distrust — it's a professional standard that experienced counterparties will recognize and respect.
