Confidentiality Agreement

Definition

A confidentiality agreement — also called an NDA — is a contract where one or both parties promise not to share certain information. Mutual NDAs go both ways. One-way NDAs protect just one side's secrets.

In Practice

Before you pitch your SaaS idea to a potential co-founder, you sign a mutual confidentiality agreement. You'll share your product roadmap and customer data; they'll share their proprietary algorithm. The agreement defines exactly what counts as 'confidential information,' how long the obligation lasts (typically 2–5 years), and what's excluded — like information that's already public or that the other party already knew.

If you're sharing specifics — financial projections, proprietary methods, customer lists, technical designs — yes. If you're just describing your idea at a high level ('an app that does X'), probably not. Ideas themselves aren't protectable; the specific execution and data around them are.
