Non-Disclosure Agreement (NDA)

Definition

A legally binding contract that establishes confidentiality obligations between parties sharing proprietary information. NDAs are essential tools for protecting trade secrets and other sensitive intangible assets during due diligence, partnership discussions, and employee onboarding.

Complementary Terms

Concepts that frequently appear alongside Non-Disclosure Agreement (NDA) in practice.

Shareholders' Agreement

A legally binding contract between a company's shareholders that governs their rights, obligations, and the rules for key decisions including share transfers, board composition, dividend policy, and exit mechanisms. Essential governance infrastructure for investor-backed companies.

Non-Compete Agreement

A contractual arrangement in which one party agrees not to engage in competitive activity for a specified period and within a defined geographic area. Non-compete agreements are recognised as identifiable intangible assets in purchase price allocations and serve to protect acquired customer relationships, trade secrets, and human capital.

SAFE (Simple Agreement for Future Equity)

A financing instrument developed by Y Combinator that provides investors with the right to receive equity at a future priced round, subject to a valuation cap and/or discount. SAFEs are simpler than convertible notes, carry no interest, and have no maturity date.

Trade Secrets

Confidential business information that provides a competitive advantage, including formulas, processes, methods, customer lists, and supplier terms. Unlike patents, trade secrets are not publicly disclosed and are protected through confidentiality agreements and security measures rather than registration.

Information Asymmetry

A situation in which one party in a transaction possesses more or better information than the other, creating an imbalance that can affect pricing and deal outcomes. Information asymmetry is particularly acute in intangible-heavy businesses, where the true value of assets such as proprietary data, know-how, and relationships is difficult for external parties to assess.

Heads of Terms

Heads of terms (also called a letter of intent or memorandum of understanding) is the short document that records the main commercial terms a buyer and seller have agreed in principle before formal contracts are drafted. It typically covers the headline price, the deal structure (a share sale or an asset sale), any earn-out, the conditions to completion, and an exclusivity period during which the seller agrees not to talk to other buyers.

Intellectual Property Audit

A systematic review of a company's intellectual property portfolio — including patents, trademarks, copyrights, trade secrets, domain names, and licences — to assess ownership, validity, enforceability, freedom to operate, and commercial relevance. IP audits are essential in M&A due diligence, technology licensing negotiations, and litigation preparation.

Teaser (M&A)

A teaser is the short, deliberately anonymous document a seller's adviser uses to test the market for a business without revealing its identity. Usually one or two pages, it summarises the sector, size, financial highlights and investment rationale in enough detail to interest a buyer but not enough to identify the company.
