Client NDAs and data licensing: what owners should know

Confidentiality agreements with clients are one of the first concerns owners raise. In most cases they shape the scope of a deal rather than ruling it out.

By the Buzz Data Desk team

Professional services firms, agencies and contractors often have confidentiality agreements with their clients. It is right to take them seriously. The good news is that they rarely stop a deal; they shape what goes into it.

Start with an inventory

Before any offer, list the client agreements that include confidentiality or data-use terms. Your lawyer can review which records each one covers and whether licensing de-identified copies is permitted, restricted or prohibited.

Exclude what is covered

Records tied to clients with restrictive terms can be left out entirely, by client, mailbox, channel or date range. Many deals go ahead with a handful of client accounts excluded and everything else in scope.

Exclusions are normal. Buyers would rather have a clean, narrower dataset than a broad one with uncertain rights.

Make it explicit in the contract

The license should list the excluded records clearly, and the buyer should confirm they will not be transferred. De-identification removes names and identifying details from what is included, but it does not replace the need to respect your agreements.

Talk it through early

Raise confidentiality on the first call. It helps match you with buyers whose programs fit, and it avoids surprises once an offer is on the table.
