Startups are known for their innovation, agility, and rapid growth. As founders and entrepreneurs, it is crucial to ensure that your intellectual property (IP), trade secrets, and sensitive business information are protected. Non-Disclosure Agreements (NDAs) and Mutual Non-Disclosure Agreements (MNDAs) play a critical role in safeguarding your startup's competitive edge.

This article will explore:

  • What is a non-disclosure agreement
  • The purpose of NDAs and MNDAs
  • Types of non-disclosure agreements
  • Key parts of every NDA
  • When startups typically use NDAs
  • Potential pitfalls and limitations of NDAs
  • Real-life case studies

Key Takeaways

  1. NDAs and MNDAs are critical tools for startups to protect their intellectual property, trade secrets, and sensitive business information.
  2. Startups commonly use NDAs during hiring, partnerships, investment pitches, product development, mergers, and to manage bad press situations.
  3. While NDAs offer protection, they come with challenges such as overly broad terms, enforcement difficulties, reputational risks, and public interest disclosures.

What is a Non-Disclosure Agreement (NDA)?

An NDA is a legally binding contract between two parties that establishes a confidential relationship. The party that discloses information, typically the startup, is known as the disclosing party.

The receiving party agrees not to disclose the confidential information to third parties without the disclosing party's consent. NDAs are designed to protect sensitive information, such as trade secrets, business strategies, customer data, and other proprietary information.

What is the purpose of NDAs and MNDAs?

1. Protecting Intellectual Property (IP)

One of the most significant assets a startup has is its intellectual property, which can include inventions, designs, software, and trade secrets. By signing an NDA or an MNDA, the receiving party agrees to keep the startup's IP confidential and not to use it for their own benefit. This protection helps startups maintain their competitive advantage and prevents unauthorized use of their IP.

2. Safeguarding Business Strategies and Confidential Information

Startups often need to share their business strategies and confidential information with potential investors, partners, employees, or consultants. NDAs and MNDAs help ensure that this information remains confidential and is not used against the startup by competitors or other third parties.

3. Building Trust in Business Relationships

NDAs and MNDAs are essential tools for building trust between startups and potential partners, investors, or employees. By signing an NDA or an MNDA, the receiving party demonstrates their commitment to confidentiality and their willingness to protect the startup's interests. This trust can help establish strong business relationships and facilitate the exchange of valuable information.

4. Protecting Trade Secrets

Trade secrets, such as unique processes, formulas, or techniques, can provide startups with a competitive edge in their industry. However, these secrets lose their value if they become public knowledge. Founders can use NDAs and MNDAs to ensure that employees, consultants, and partners do not disclose trade secrets to competitors or other third parties.

Types of Non-disclosure Agreements

When it comes to protecting sensitive information, startups typically encounter two main types of Non-Disclosure Agreements:

Unilateral NDA

  • A one-sided agreement where the startup discloses specific confidential information to another party.
  • Ideal when presenting innovative concepts, business strategies, or proprietary data to potential investors, clients, or contractors.
  • Ensures that the receiving party cannot legally share or use the information for their advantage without facing potential legal repercussions.

Mutual NDA:

  • A reciprocal agreement where both the startup and the other party exchange and protect confidential details.
  • Common in situations like joint ventures, collaborations, or when two businesses are considering a merger and need to share financial or operational details.
  • Provides a safety net for both parties, ensuring that shared information remains confidential and isn't misused.

For startups, understanding the distinction and appropriate application of these NDAs is crucial to maintain competitive advantage and trust in business relationships.

Key Elements of NDAs and MNDAs

1. Definition of Confidential Information

A well-drafted NDA or MNDA should clearly define what information is considered confidential. This can include specific details, such as technical data, financial information, and customer lists, as well as broader categories, such as trade secrets and business strategies.

2. Obligations of the Receiving Party

The agreement should outline the receiving party's obligations to protect the confidential information, including not disclosing it to third parties, using it only for the agreed-upon purpose, and maintaining its confidentiality. The agreement may also require the receiving party to return or destroy the confidential information upon the termination of the agreement or at the request of the disclosing party.

3. Duration

The NDA or MNDA should specify the duration of the agreement, which can range from a few months to several years, depending on the nature of the information and the relationship between the parties. The agreement may also include a survival clause, which extends the confidentiality obligations beyond the termination of the agreement.

4. Exceptions

NDAs and MNDAs should include exceptions for information that is already in the public domain, is independently developed by the receiving party, or is required to be disclosed by law or a court order.

5. Governing Law and Jurisdiction

The agreement should specify the governing law and jurisdiction that will apply in the event of a dispute. This can help ensure that any legal action taken in response to a breach of the agreement will be heard in a court familiar with the relevant laws.

When Do Startups Typically Use NDAs?

While the applications of NDAs are vast, there are specific scenarios where their use is almost mandatory for startups. Here are some typical scenarios where startups commonly deploy NDAs.

1. Hiring Process: During interviews and onboarding, startups often share insights into their future projects and unique methodologies. An NDA ensures that potential employees or new hires maintain the confidentiality of this information, safeguarding the company's competitive edge.

2. Partnerships and Collaborations: When startups collaborate with other businesses or entities, there's an exchange of data, resources, and strategies. NDAs ensure that the shared information remains exclusive to the partnership, preventing any unauthorized disclosures.

3. Investment Pitches: Seeking funding requires startups to reveal detailed business plans and growth strategies to potential investors. There are times when it is a good idea for NDAs to protect these details, ensuring that investors can't share or misuse the information. However most of the time it’s actually not the best course of action. Why? Read more in our article on when should you send your prospective investors an NDA.

4. Product Development and Innovation: In the process of bringing ideas to life, startups often engage with external designers, developers, and consultants. NDAs prevent these third parties from replicating or sharing the startup's innovations.

5. Mergers and Acquisitions: Whether being acquired or considering a merger, startups delve into deep discussions about their finances, operations, and future plans. NDAs ensure that these sensitive negotiations remain under wraps, preserving the integrity of the deal.

6. Bad Press: Sometimes, startups face situations that could lead to negative publicity. In such cases, they might ask employees or other involved parties to sign NDAs to prevent the spread of potentially damaging information. For instance, if a product fails or there's an internal dispute, an NDA can stop employees from discussing these matters publicly, protecting the startup's reputation.

Potential Pitfalls and Limitations of NDAs

While Non-Disclosure Agreements (NDAs) are invaluable tools for startups aiming to protect their proprietary information, they are not without their challenges and limitations. Here are some of the potential pitfalls startup founders should be aware of:

  • Overly Broad or Vague Terms: NDAs that lack specificity can lead to disputes. Without clear definitions, there's room for misinterpretation, making it difficult to determine what exactly is "confidential."
  • Challenges in Enforcement: Even with a solid NDA, ensuring compliance can be tough. Legal actions against breaches can be costly and time-consuming, with no guarantee of a favorable outcome.
  • Reputational Risks: An NDA that appears too restrictive can deter potential partners or employees. It might signal a lack of trust, potentially harming the startup's image in the industry.
  • Public Interest Disclosures: NDAs cannot prevent disclosures deemed in the public's interest, such as whistleblowing on illegal activities. In such cases, enforcing an NDA might backfire both legally and in terms of reputation.

In essence, while NDAs offer a protective shield for startups, it's crucial to approach them with a balance of caution and clarity. Properly drafted and fair NDAs can provide the protection startups need without the accompanying pitfalls.

Real-life Case Studies

While it is essential to recognize that every situation is unique and not all cases of information leaks or intellectual property theft are due to the absence of NDAs or MNDAs, there have been several instances where startups faced significant challenges due to a lack of proper confidentiality agreements. Here are a few examples:

1. Nikola Corporation vs. Tesla Inc.

In 2020, Nikola Corporation, an electric truck startup, sued Tesla Inc., claiming that Tesla had infringed on Nikola's patented truck design. Nikola alleged that Tesla's Semi truck design borrowed elements from Nikola's design, which was protected by several patents. The lawsuit demanded over $2 billion in damages. The case centered around the alleged infringement of intellectual property rather than a breach of an NDA or MNDA. However, it illustrates the potential risks startups face when sharing their designs and innovations with others. If Tesla had worked with Nikola in some capacity, having an NDA or MNDA in place could have helped protect Nikola's design and avoided costly litigation.

2. Waymo vs. Uber

In 2017, Waymo, a self-driving car technology company owned by Alphabet (Google's parent company), sued Uber, claiming that one of its former engineers, Anthony Levandowski, had stolen trade secrets related to autonomous vehicle technology. Waymo alleged that Levandowski had downloaded over 14,000 confidential files, including proprietary designs for Lidar technology, before leaving the company and founding his own startup, Otto. Uber later acquired Otto, which allegedly led to Uber's development of Lidar technology using Waymo's trade secrets. While the parties eventually reached a settlement, the case highlights the importance of having strong confidentiality agreements in place when sharing sensitive information with employees and other parties.

3. Jawbone vs. Fitbit

In 2015, Jawbone, a wearable technology company, sued Fitbit, a competitor, claiming that Fitbit had lured several of its employees, who then allegedly took sensitive information and trade secrets with them. Jawbone accused Fitbit of gaining access to its product plans, market research, and other confidential information. This case demonstrates the importance of having NDAs in place with employees, as well as the need to enforce such agreements when employees move to competitors.

4. Snapchat (Snap Inc.) vs. Reggie Brown

In 2013, Reggie Brown, a former friend and classmate of Snapchat co-founders Evan Spiegel and Bobby Murphy, filed a lawsuit against the company, claiming that he had come up with the idea for Snapchat and had been unfairly ousted from the venture. The case was eventually settled, with Snapchat agreeing to pay Brown $157.5 million. While the case did not revolve around the breach of an NDA, it underscores the importance of having clear agreements in place early on, outlining the roles, responsibilities, and ownership of ideas among co-founders.

These examples illustrate the potential consequences that startups may face if they fail to establish strong confidentiality agreements, such as NDAs and MNDAs, with employees, partners, and investors. Implementing these agreements can help startups protect their intellectual property, trade secrets, and sensitive information, thereby safeguarding their competitive edge and long-term success.


In today's fast-paced and competitive business environment, startups need to protect their intellectual property, trade secrets, and sensitive information to maintain their competitive edge.

NDAs and MNDAs are essential tools that can help founders safeguard their startups' interests, build trust with partners, investors, and employees, and establish a strong foundation for growth and success.

By understanding the purpose and key elements of these agreements, founders can ensure that their startups remain protected and well-positioned for long-term success.
