Mutual NDA for AI development

Most agencies sign one-way NDAs where only the client is protected. AI work needs mutual: methodology, prompt patterns, and architectural choices are agency IP too. Here is when to sign, what to include, and what to push back on.

Mutual

Signed before any product discussion

  • Both parties protected
  • Methodology carve-out included
  • 3-year term, standard remedies

Critical clauses

Five clauses every mutual NDA should have

Without these, the document is either toothless (no remedies) or overreaching (no carve-outs). Both fail in court.

  • Definition of confidential information

    Specific, not “everything we discuss”. Information disclosed in connection with discussions about a potential engagement, in any form (oral, written, electronic, demos).

  • Carve-outs

    Independently developed, publicly known through no fault of the receiving party, prior knowledge, or required by law. Without these, the NDA is unenforceable in most jurisdictions.

  • Term

    Two to three years for product information. Indefinite for trade secrets. Match the term to the half-life of the information; an indefinite term on a 6-month roadmap is overreaching.

  • Remedies

    Injunctive relief plus damages. Without injunctive relief, the receiving party can monetise a breach faster than damages can compensate.

  • Methodology carve-out

    The agency keeps generic templates, prompt patterns, and process documentation as agency IP. Without this clause, the agency’s pre-existing work is at risk.

Red flags

What to push back on, on either side

In client NDAs

  • Indefinite term on all information

    Overreaching. Most product information has a 2 to 3 year half-life; demanding indefinite protection on everything signals the lawyer wrote the template once and never revisited it.

  • Penalty clauses (e.g. “any breach $100K”)

    Generally unenforceable in most jurisdictions. Liquidated damages must reflect actual harm. A flat penalty signals bad-faith drafting.

  • Auto-extension clauses

    Renews the agreement silently. Push back; require explicit re-signing.

  • Choice of law in unfavorable jurisdiction

    “Disputes resolved in the State of [client’s home]” is normal. “Disputes resolved in [obscure offshore jurisdiction]” is a red flag.

  • IP-grab language

    “All derivative works belong to client” covers more than the engagement. The agency’s methodology, generic templates, and prior work product are not derivative works of your project.

In agency NDAs (clients should watch)

  • Vague definition of agency methodology

    If “methodology” is undefined, it could be claimed to include client work product. Insist on a specific list (templates, prompt patterns, process documentation).

  • Long indemnification on unrelated matters

    Indemnification should map to NDA breaches, not general business risk. Watch for clauses that pull in IP infringement or third-party claims.

  • Non-compete language disguised as NDA

    “Receiving party shall not engage similar service providers” has nothing to do with confidentiality. Strike it.

Template clauses

Sample language you can adapt

Drop-in clauses we use as a starting point. Have a lawyer adapt them to your jurisdiction; this is not legal advice.

DEFINITION. "Confidential Information" means any non-public
information disclosed by one party (the "Disclosing Party")
to the other party (the "Receiving Party") in connection with
the parties' discussions of a potential business relationship,
whether disclosed orally, in writing, electronically, or
through demonstrations.

CARVE-OUTS. Confidential Information shall not include
information that: (a) was known to the Receiving Party prior
to disclosure; (b) is or becomes publicly available through
no fault of the Receiving Party; (c) was independently
developed by the Receiving Party; or (d) is required to be
disclosed by law.

METHODOLOGY CARVE-OUT. Notwithstanding the foregoing,
"Confidential Information" of Service Provider shall be
deemed to include and continue to protect Service Provider's
pre-existing methodology, prompt templates, and process
documentation regardless of whether such items are referenced
in connection with this Agreement.

TERM. Each party's obligations under this Agreement shall
continue for three (3) years from the date of disclosure,
except that obligations regarding trade secrets shall
continue indefinitely.

REMEDIES. Each party acknowledges that breach may cause
irreparable harm and that the non-breaching party shall be
entitled to seek injunctive relief in addition to any other
remedies available at law.

Common mistakes

Five NDA mistakes that cost trust or money

  • Signing a one-way client NDA without reading it

    Common, especially under deadline pressure. Ten minutes of review saves a year of regret. Read every clause; ask about every term you do not recognise.

  • Refusing to sign mutual

    If a client refuses to sign mutual after the agency requests it, that is a low-trust signal. Most serious clients sign mutual without question.

  • Sharing competitor names in the NDA conversation

    “We’re also talking to [competitor]” creates risk for the agency and tells the agency you are price-shopping. Both are unhelpful.

  • Treating NDA as scope-of-work

    NDA covers confidentiality. SOW covers deliverables, price, timeline, IP ownership. Two separate documents.

  • Skipping NDA to save time

    Saves an hour, costs trust if you accidentally share something sensitive. Sign first, talk second.

FAQ

Common questions on mutual NDAs

Do I need a lawyer to review my NDA?

Yes for the first NDA with a new agency. Subsequent engagements with the same template can usually be reviewed in-house. The first review establishes baseline trust in the template; subsequent uses inherit it.

Can I share my own NDA template?

Most clients do. Many agencies prefer to start from a mutual template they already use, which has been negotiated across many engagements. Either is fine; what matters is that the final document is mutual and balanced.

What happens if the NDA is breached?

Injunctive relief (court order to stop the breach) plus damages. Practical enforcement is hard in cross-border situations, but reputational damage to a serial breacher is real and lasting.

Should the NDA reference the SOW?

Generally separate documents. Cross-references are fine (e.g. NDA survives termination of SOW), but neither should be embedded in the other.

Does mutual NDA expire?

Term is negotiable. Three years for general product information, indefinite for trade secrets. Both are common. The strict legal half-life of most product information is shorter than the term suggests.

What is a methodology carve-out?

A clause that excludes the agency’s pre-existing methodology, prompt templates, and process documentation from the definition of confidential information. Without it, the agency’s prior work is at risk every time it signs an NDA.
