Mutual Non-Disclosure Agreement (NDA)
Non-Disclosure Agreement
Vantage Dynamics BV — Disclosing/receiving party (drafter) · You (the undersigned) — Recipient
La conclusión
On the label this is a 'mutual' NDA — both sides promise to keep each other's secrets while exploring a deal. In practice, three clauses tilt it toward Vantage. The residuals clause (Section 3) is the big one: anything their people 'remember' from your confidential information, they can use freely, forever — a memory-sized loophole in the whole agreement, and it only runs in THEIR favor. The definition of confidential information is extremely broad (anything said, written, or even observed, marked or not), which sounds protective but mostly creates risk for whoever handles more of the other side's information. And the obligations are asymmetric in small ways that add up: you must certify destruction of their data in 10 days; they only owe 'commercially reasonable efforts'. A five-year confidentiality tail plus injunctive relief without bond is aggressive but survivable. Overall: a usable NDA after you strike or mutualize the residuals clause — do not sign it as-is if your know-how is the valuable part of the conversation.
Señales de alerta
Residuals clause lets them keep what they 'remember'
Crítico· Propiedad intelectualSection 3 lets Vantage freely use any ideas, concepts, know-how and techniques their people retain in memory from your confidential disclosures — for any purpose, forever, with no payment. It runs one way only. For a technical or product discussion, this is a free license to your thinking dressed up as boilerplate.
Qué pedir
Delete the residuals clause, or make it strictly mutual and carve out your core know-how explicitly.
One-sided remedies and duties throughout
Alto· OtrosThe injunction right (Section 7) and the strict return-and-certify duty (Section 6) are written for Vantage only; you get 'commercially reasonable efforts' in return. Individually small, together they mean the enforcement machinery of this 'mutual' NDA points at you.
Qué pedir
A find-and-replace fix: every right and duty should read 'either Party' / 'each Party'. A counterparty acting in good faith will accept this in minutes.
Five-year confidentiality tail on an everything-definition
Medio· RescisiónA 5-year tail on a definition that includes unmarked oral statements means that until 2033 you must track what was said in a meeting in 2026. Compliance is nearly impossible to prove; accidental breach is easy to allege.
Qué pedir
Three-year tail, and a marking requirement so both sides know exactly what is protected.
Hiring restriction hidden in an NDA
Medio· No competenciaThe 12-month non-solicit binds only you and lives in a document most people skim for secrecy terms only. If your company might ever want to hire someone you meet in these meetings, this clause is a lawsuit waiting.
Qué pedir
Mutual non-solicit with a general-job-ads carve-out — or delete it; it doesn't belong in an NDA.
Plazos clave
- Agreement expiry (2-year term)
Two years from signature. Diary it — the confidentiality tail (5 more years) starts running from here.
- Return/destruction certificate
If they request return of materials, you have 10 business days to return or destroy AND certify in writing.
- Non-solicitation ends
12 months after the agreement ends — until then, don't recruit their staff you met through this deal.

Cláusula por cláusula
1. Definition of Confidential Information
Medio· OtrosLo que dice el contrato
“"Confidential Information" means any and all information disclosed by either Party, whether oral, written, electronic or observed, whether or not marked as confidential, including but not limited to business plans, financial data, customer lists, technical know-how, product roadmaps, and the existence and terms of the Parties' discussions.”
Lo que significa
Everything counts as confidential — even things said out loud and never marked. That sounds protective, but a definition this broad is hard to comply with and hard to enforce: you can breach it without knowing, and courts sometimes refuse to enforce definitions that swallow everything. It also protects the drafter more, because you'll likely handle more of their material than they handle of yours.
Consejo de negociación
Ask to require written information to be marked 'Confidential' and oral disclosures to be confirmed in writing within 30 days. That's the market standard and protects both sides equally.
2. Obligations
EstándarLo que dice el contrato
“Each Party shall (a) hold the other's Confidential Information in strict confidence; (b) not disclose it to any third party without prior written consent; (c) use it solely for the Purpose; and (d) protect it with at least the same degree of care it uses for its own confidential information, and no less than reasonable care.”
Lo que significa
The core promise, and it's fair: keep it secret, don't share it, only use it to evaluate the deal, take reasonable care. This clause is genuinely mutual and matches market standard.
3. Residuals — the memory loophole
Crítico· Propiedad intelectualLo que dice el contrato
“Notwithstanding Section 2, Vantage shall be free to use any Residuals for any purpose. "Residuals" means information in non-tangible form retained in the unaided memory of Vantage's personnel who had access to the Recipient's Confidential Information, including ideas, concepts, know-how and techniques.”
Lo que significa
This quietly cancels the NDA for anything their team can remember. If their engineers 'retain in unaided memory' your ideas, concepts, know-how or techniques, Vantage may use them for any purpose — build a competing product, share them, anything. Note the direction: only VANTAGE gets this right, not you. For a know-how conversation, this clause converts your pitch into a free technology transfer.
Consejo de negociación
Ask for the residuals clause to be deleted — many companies drop it when challenged. If they insist, make it strictly mutual AND exclude your core know-how by name. Never discuss your 'secret sauce' while a one-way residuals clause is in force.
4. Term and Survival
Medio· RescisiónLo que dice el contrato
“This Agreement takes effect on the date of signature and continues for two (2) years. The confidentiality obligations survive for five (5) years after termination or expiry, and indefinitely for trade secrets.”
Lo que significa
You're bound to secrecy for up to seven years total (2-year term + 5-year tail), and forever for trade secrets. Market standard is a 3-year tail; five is long but not outrageous. The indefinite trade-secret carve-out is normal.
Consejo de negociación
Ask to shorten the survival period to three years — in fast-moving industries most confidential information is stale long before year five.
6. Return or Destruction — asymmetric homework
Medio· OtrosLo que dice el contrato
“Upon written request, the Recipient shall within ten (10) business days return or destroy all Confidential Information of Vantage and certify such destruction in writing. Vantage shall use commercially reasonable efforts to do likewise.”
Lo que significa
Spot the asymmetry: you must return/destroy and CERTIFY within 10 business days; they only owe 'commercially reasonable efforts' with no deadline and no certificate. Small clause, but it shows who the document was written for.
Consejo de negociación
Make the obligation identical in both directions — same deadline, same written certification. Also add the standard carve-out for automatic IT backups, or you can't technically comply.
7. Injunctive Relief without bond
Alto· Resolución de disputasLo que dice el contrato
“The Recipient acknowledges that any breach of this Agreement will cause Vantage irreparable harm for which damages are an inadequate remedy, and Vantage shall be entitled to injunctive relief without the need to post a bond, in addition to all other remedies.”
Lo que significa
You pre-agree that any breach (however trivial) causes 'irreparable harm', letting Vantage run to court for an injunction without posting the usual financial guarantee. And again — the right is written for Vantage only.
Consejo de negociación
Mutualize it ('either Party shall be entitled…') and soften 'any breach will cause' to 'a breach may cause' irreparable harm — courts decide, not the contract.
8. Non-Solicitation
Medio· No competenciaLo que dice el contrato
“For the term of this Agreement and twelve (12) months thereafter, the Recipient shall not solicit for employment any employee of Vantage with whom it came into contact in connection with the Purpose.”
Lo que significa
For up to three years (2-year term + 12 months) you can't recruit Vantage employees you met during the discussions. It binds only you, and note an NDA is a strange home for a hiring restriction — it often slips through unread here.
Consejo de negociación
Make it mutual, and add the standard carve-out: responses to general public job postings don't count as solicitation.
9. Governing Law and Jurisdiction
Bajo· Resolución de disputasLo que dice el contrato
“This Agreement is governed by the laws of the Netherlands. The courts of Amsterdam have exclusive jurisdiction over any dispute arising from this Agreement.”
Lo que significa
Dutch law, Amsterdam courts — their home turf. Any dispute means litigating abroad in their backyard, which raises your cost of enforcing your own rights.
Consejo de negociación
If you have leverage, propose your jurisdiction or a neutral one. If not, at least price in that enforcement abroad is expensive before sharing your most sensitive material.
