DeepSeek for M&A Due Diligence is best understood as a practical AI layer for deal teams: it can summarize large document sets, compare target companies, extract contract terms, organize diligence findings, and draft clear notes for investment committees. It does not replace bankers, lawyers, accountants, consultants, or operating leaders. Used well, it helps them spend less time hunting through documents and more time judging what the findings mean for price, structure, risk allocation, and integration planning.
This guide explains where DeepSeek can fit across the due diligence workflow, from early deal screening to virtual data room review, post-merger integration risks, and synergy tracking. It also covers the controls that matter in real transactions: confidentiality, source verification, human review, and clear ownership of AI-assisted outputs.
What M&A Due Diligence Means and Why It Is So Hard
M&A due diligence is the structured investigation a buyer, investor, lender, or advisor performs before completing a merger, acquisition, minority investment, carve-out, or financing. The goal is to understand what is actually being bought, what risks come with it, and whether the investment thesis still holds after closer inspection.
In plain English, diligence turns a promising deal story into a tested view of reality. A target may show strong revenue growth, but diligence asks whether that growth depends on one customer, one reseller, one founder, one expiring contract, or one accounting assumption. A business may look profitable, but diligence asks whether margins will survive after standalone costs, integration costs, cyber remediation, retention payments, or regulatory conditions.
The work is difficult because most deal teams operate under time pressure. A virtual data room may contain thousands of files: contracts, board minutes, employee plans, financial statements, tax schedules, customer lists, product documentation, litigation summaries, insurance policies, intellectual property records, compliance materials, and technical architecture diagrams. Each file can contain a clue that changes valuation, purchase agreement terms, indemnities, or integration priorities.
The biggest challenge is not simply reading documents. It is connecting facts across workstreams. A customer concentration issue may affect revenue quality, debt capacity, legal disclosure, and Day 1 communications. A change-of-control clause may affect closing certainty and post-close revenue. A weak ERP system may create integration cost, reporting risk, and delayed synergy realization. This is where AI due diligence tools can help, provided the team uses them as analytical assistants rather than unquestioned authorities.
What DeepSeek Is and Why It Fits Due Diligence Work
DeepSeek is a family of large language models, or LLMs. An LLM is an AI system trained to process and generate language, which makes it useful for tasks such as summarization, classification, comparison, question answering, drafting, and structured extraction. DeepSeek has drawn attention for reasoning-focused models and long-context document workflows; DeepSeek’s official API documentation lists current model capabilities such as long context, JSON output, tool calls, and thinking modes. Teams should always verify the current documentation before implementation because model names, features, and limits can change.

For deal teams, the practical value is not that DeepSeek “knows M&A.” The value is that it can process source material quickly, follow instructions, create structured outputs, and highlight patterns that a human reviewer can verify. For example, it can turn 200 vendor contracts into a list of renewal dates, consent requirements, termination rights, and unusual pricing terms. It can compare management’s growth narrative against customer churn disclosures. It can draft a first-pass issues list for a quality of earnings, legal, commercial, or IT diligence team.
DeepSeek is especially relevant when paired with retrieval-augmented generation, often shortened to RAG. RAG means the model answers questions using a controlled set of uploaded or indexed source documents rather than relying only on its general training. In diligence, that matters because a deal team needs traceable answers: document name, page or section, quoted excerpt, confidence level, and reviewer notes.

For technical background, DeepSeek-R1 research describes reinforcement-learning approaches aimed at improving reasoning behavior, which is relevant to multi-step analytical tasks such as comparing clauses, ranking risk severity, and checking assumptions.

DeepSeek for M&A Due Diligence Across the Deal Lifecycle
DeepSeek can support the full deal lifecycle, but the highest-value use cases usually fall into four areas: deal screening, document review, integration risk assessment, and synergy notes. The right workflow depends on transaction size, data sensitivity, regulatory exposure, and the team’s ability to verify the model’s outputs.
| Diligence area | How DeepSeek can help | Human review required |
|---|---|---|
| Deal screening | Summarize target profiles, compare market positioning, and organize preliminary red flags. | Validate sources, financial assumptions, strategic fit, and valuation logic. |
| Document review | Extract contract terms, obligations, exceptions, and inconsistencies from data room files. | Confirm legal meaning, materiality, and purchase agreement implications. |
| Integration risks | Identify people, systems, process, compliance, and customer risks that may affect Day 1 and beyond. | Prioritize risks with operating leaders and integration workstream owners. |
| Synergy notes | Document cost and revenue synergy assumptions, dependencies, timing, and evidence. | Approve the synergy model, accountability, timing, and tracking cadence. |
Deal Screening: Faster Target Triage Without Losing Strategic Judgment
Deal screening is the early stage of evaluating acquisition targets before a full diligence process begins. Corporate development teams, private equity associates, and investment banking analysts may review dozens or hundreds of companies to decide which deserve management attention.
DeepSeek can speed up this stage by standardizing target summaries. A team can feed it approved source materials such as public filings, investor presentations, company websites, market reports, news articles, and CRM notes. The model can then produce a consistent screening memo covering business model, customer base, growth drivers, likely valuation considerations, strategic rationale, known risks, and open questions.
The key is to separate source-based facts from hypotheses. For example, “the company reports 42% of revenue from enterprise customers” is a source-based fact if it appears in an investor deck. “The company may be a cross-sell opportunity” is a hypothesis that needs commercial diligence. DeepSeek should label these differently so decision-makers do not confuse AI-generated reasoning with confirmed evidence.
A strong deal screening workflow uses DeepSeek to create a first-pass target view, then asks analysts to challenge it. What evidence is missing? Which assumptions are too optimistic? What would make the deal unattractive? Which diligence questions should be asked before signing an NDA or entering a competitive auction?
Document Review: Turning the Data Room Into a Structured Issues List
Document review is where AI can create immediate leverage. In a traditional process, junior team members and specialist advisors manually inspect data room documents, tag issues, and summarize findings for workstream leads. This work is necessary, but it is repetitive and easy to fragment across legal, finance, tax, commercial, HR, IT, and operations teams.
DeepSeek can help by extracting structured information from contracts, policies, schedules, and financial support files. For legal diligence, that may include assignment restrictions, change-of-control clauses, exclusivity obligations, most-favored-nation clauses, termination rights, non-competes, data processing terms, indemnities, audit rights, and unusual notice periods. For finance diligence, it may include revenue recognition notes, debt-like items, working capital adjustments, related-party transactions, customer credits, and non-recurring expenses.
Professional services firms are already describing generative AI as a way to automate parts of due diligence document review while still relying on human experts to interpret materiality and risk. Deloitte, for example, notes that generative AI can review financial, legal, and operational documents, summarize them, and highlight risks or opportunities for human evaluation. Deloitte on generative AI in M&A.
Below is one practical example a deal analyst could adapt for contract analysis. It assumes the team is working inside an approved, secure environment and has permission to process the documents. The prompt is designed to produce source-grounded findings with exact excerpts, confidence levels, and reviewer follow-up questions rather than high-level summaries.
You are assisting with legal and commercial due diligence for a proposed acquisition. Review the uploaded contract set and return a table containing: 1. Document name 2. Counterparty 3. Clause type 4. Exact excerpt 5. Page or section reference 6. Risk category 7. Commercial impact 8. Confidence level (High / Medium / Low) 9. Reviewer follow-up question Focus on identifying: - Change-of-control restrictions - Assignment consent requirements - Termination rights - Exclusivity clauses - Most-favored-nation (MFN) clauses - Unusual indemnities - Data protection obligations - Renewal and notice periods Do not infer missing terms or create information that is not supported by the source documents. If a clause cannot be found, state "Not found in the provided documents." Every material finding must include the exact excerpt together with its source reference.
This prompt encourages evidence-based review instead of free-form summarization. Every important finding is linked to an exact excerpt and source reference, while confidence levels and follow-up questions help reviewers distinguish confirmed evidence from items that require additional legal or commercial analysis.
Contract Review Output Template
For contract review, the most useful DeepSeek output is not a narrative summary. Deal teams should request a structured table that makes every finding easy to verify against the source document.
| Field | What it should capture |
|---|---|
| Source document | The exact file name, contract title, schedule, or data room reference. |
| Exact excerpt | The quoted language supporting the finding, not a paraphrase only. |
| Clause or issue type | For example, change of control, assignment, termination, renewal, MFN, indemnity, data protection, or exclusivity. |
| Risk category | Legal, commercial, financial, operational, regulatory, tax, IT, or HR. |
| Confidence level | High, medium, or low, based on how clearly the source supports the finding. |
| Owner | The person or workstream responsible for reviewing the issue. |
| Follow-up question | The next question for counsel, management, the seller, or the relevant diligence advisor. |
This template reduces the risk of vague AI summaries. It also helps reviewers separate confirmed source-based issues from items that require additional legal, commercial, or financial analysis.
Integration Risks: Finding Problems Before They Become Day 1 Surprises
Post-merger integration is the process of combining two businesses after signing or closing. It includes decisions about people, systems, reporting lines, technology platforms, customer communications, brands, offices, vendors, governance, compliance, and operating processes. Integration is where many deal models become real or break down.
DeepSeek can support integration planning by scanning diligence findings and producing risk maps by function. For HR, it can summarize retention risks, compensation plan conflicts, union or works council issues, contractor dependence, and leadership gaps. For IT, it can compare ERP, CRM, cybersecurity, identity management, data warehouse, and product architecture notes. For legal and commercial teams, it can surface customer consent requirements, vendor termination rights, regulatory filing dependencies, and transition service agreement risks.
This matters because integration planning should not wait until the deal closes. McKinsey has long emphasized that merger integration and synergy capture require early planning, clear ownership, and a roadmap that connects diligence findings to value creation. McKinsey perspectives on merger integration
A practical DeepSeek workflow is to create an integration risk register. Each risk should include the source document, affected function, severity, timing, owner, mitigation action, dependency, and open question. The model can draft the register, but leaders must decide priorities. A minor contract issue may be low risk in one transaction and critical in another if it affects a top customer, regulated product, or closing condition.
Integration Risk Register Template
An integration risk register helps convert scattered diligence findings into an actionable Day 1 and post-close workplan. DeepSeek can draft the register, but functional leaders should confirm priority, ownership, and mitigation plans.
| Field | Example use |
|---|---|
| Risk | Customer consent required before contract assignment. |
| Function | Legal, sales, finance, IT, HR, operations, or compliance. |
| Source | Contract, management response, board deck, IT inventory, HR file, or diligence note. |
| Severity | High, medium, or low based on business impact and timing. |
| Owner | The workstream lead responsible for resolving or monitoring the issue. |
| Mitigation | The proposed action, such as obtaining consent, renegotiating a term, preparing a TSA, or creating a Day 1 control. |
| Deadline | Signing, closing, Day 1, first 100 days, or later integration milestone. |
| Status | Open, under review, escalated, mitigated, or closed. |
The register should not be treated as an AI-generated truth file. It is a working tool that helps integration leaders track issues, assign accountability, and connect diligence findings to execution risk.
Synergy Notes: Making Revenue and Cost Assumptions Easier to Audit
Synergies are the expected benefits from combining two companies. Cost synergies may come from consolidating vendors, facilities, software licenses, overlapping roles, insurance policies, or procurement. Revenue synergies may come from cross-selling, geographic expansion, channel access, product bundling, pricing improvements, or higher customer retention.
Synergies are often presented confidently in investment committee materials, but they depend on assumptions. DeepSeek can help deal teams document those assumptions more clearly. It can turn scattered diligence notes into a synergy log showing the value driver, evidence, calculation method, implementation cost, timing, owner, dependency, confidence level, and risks to realization.
For example, if the deal model assumes procurement savings from consolidating cloud vendors, DeepSeek can organize the contracts, renewal dates, termination restrictions, volume commitments, current spend, and integration dependencies. If the model assumes cross-selling to enterprise customers, the model can help compare customer segments, product overlap, sales coverage, account ownership, and contractual restrictions.
The benefit is accountability. A synergy note should make it easy for the CFO, integration management office, and board to see what has been validated, what is still speculative, and what must happen after signing. For teams building repeatable AI-assisted workflows, Chat-Deep.ai’s guide to using DeepSeek for business workflows is a helpful next step.
Synergy Log Template
A synergy log makes value creation assumptions easier to test, challenge, and track after signing. DeepSeek can help organize the evidence behind each assumption, but finance and operating leaders must approve the final numbers.
| Field | What to include |
|---|---|
| Synergy type | Cost synergy, revenue synergy, working capital improvement, procurement saving, technology consolidation, or operating efficiency. |
| Evidence | The source documents, contracts, spend data, customer data, or management responses supporting the assumption. |
| Calculation method | The formula or logic used to estimate the synergy value. |
| Timing | When the benefit is expected: Day 1, first 100 days, year one, year two, or later. |
| Cost to achieve | One-time implementation cost, severance, migration cost, advisory cost, system cost, or retention cost. |
| Confidence level | High, medium, or low depending on evidence quality and execution complexity. |
| Owner | The executive, integration lead, or functional owner responsible for delivering the synergy. |
This structure helps prevent optimistic synergy assumptions from becoming unsupported claims. Every material synergy should have evidence, timing, cost-to-achieve, ownership, and a clear confidence level.
Where DeepSeek Performs Well—and Where It Should Not Be Trusted Blindly
DeepSeek is strongest when the task has clear source documents, a narrow objective, and a structured output. Contract clause extraction, data room summarization, issue list drafting, document comparison, management presentation review, and diligence Q&A are good examples. The model is also useful for multilingual review when a cross-border deal includes documents in multiple languages, though legal translation and local-law interpretation still require qualified professionals.
DeepSeek is weaker when the task requires final judgment, negotiation strategy, legal advice, accounting conclusions, valuation decisions, or facts that are not present in the provided sources. It may also miss context, overstate weak evidence, or produce fluent but incorrect answers. These risks are common to generative AI systems, not unique to DeepSeek.
The safest approach is to require source-grounded outputs. Every important AI-generated finding should link back to the underlying document, page, clause, schedule, spreadsheet tab, or management response. If the model cannot provide a source, the finding should be treated as an idea to investigate, not a diligence conclusion.
Long context does not guarantee accuracy. A model may be able to process a large source set and still miss a clause, misread a table, overstate a weak signal, or connect facts incorrectly. Retrieval-augmented generation can improve traceability by grounding answers in selected documents, but it does not remove the need for sampling, source checks, expert review, and reviewer sign-off.
In practice, DeepSeek should be treated as a structured review assistant rather than a final diligence authority. The more material the issue, the more important it is to verify the source document, challenge the interpretation, and document the human decision.
Confidentiality, Security, and Human Oversight in Deal Work
M&A data is highly sensitive. Data rooms can contain non-public financials, customer names, employee compensation, source code, trade secrets, pending litigation, tax positions, regulated data, and competitively sensitive strategy. A deal team should not upload confidential target information into any AI tool unless the use is permitted by the NDA, approved by counsel, reviewed by security, and consistent with privacy and data-transfer obligations.
Before using DeepSeek in a live transaction, teams should review the applicable privacy policy, API terms, deployment model, logging practices, access controls, retention terms, and data residency. DeepSeek’s privacy policy describes categories of personal data collection and processing, while the open platform terms should be reviewed for API-based use cases. DeepSeek Privacy Policy DeepSeek Open Platform Terms
Security review should be practical, not theoretical. Decide whether the work belongs in a public chatbot, an enterprise API environment, a private cloud deployment, or a self-hosted model. For regulated, confidential, or strategically sensitive deals, teams should compare these options with counsel, information security, procurement, and compliance. Chat-Deep.ai’s guide to hosted API, private deployment, and self-hosting choices can help frame that evaluation.
AI governance should also define who can use the model, which documents are allowed, how prompts are stored, how outputs are reviewed, and how mistakes are corrected. The NIST AI Risk Management Framework is a useful reference for building governance around AI risks, including mapping, measuring, managing, and governing AI systems. NIST AI Risk Management Framework
Legal teams have additional professional obligations. The American Bar Association has warned that lawyers using generative AI must consider duties such as competence, confidentiality, communication, supervision, and accuracy. ABA guidance on lawyers using generative AI The broader lesson applies to all deal professionals: AI can accelerate review, but accountability stays with the humans signing the memo, advising the client, approving the model, or negotiating the purchase agreement.
Deployment Decision Matrix for M&A Workflows
The right DeepSeek deployment model depends on deal sensitivity, client instructions, data residency, security controls, and regulatory exposure. A workflow that is acceptable for public market research may be unacceptable for confidential target documents.
| Deployment option | Suitable for | Not suitable for |
|---|---|---|
| Public chatbot | Public information, generic prompts, non-confidential drafting, and training examples. | Confidential contracts, data room files, non-public financials, employee data, board materials, or investor materials. |
| Hosted API | Approved internal workflows with reviewed terms, access controls, logging rules, and data handling procedures. | Highly sensitive transactions without legal, privacy, security, and client approval. |
| Private cloud deployment | Enterprise diligence workflows that require stronger access control, environment isolation, and internal governance. | Teams without the technical, legal, and security capacity to manage the environment properly. |
| Self-hosted model | Highly sensitive, regulated, or strategically important deal work where the buyer needs maximum control over infrastructure and data handling. | Small teams that cannot maintain model operations, security monitoring, updates, and audit controls. |
For confidential M&A work, DeepSeek should not be used casually as a public chatbot. Deal teams should use only an approved enterprise API, private deployment, or self-hosted environment after NDA, legal, security, privacy, and client approvals.
What Not to Upload Into an Unapproved AI Tool
Deal teams should create a clear list of materials that must never be uploaded into an unapproved AI tool. In M&A, the safest default is to treat data room materials as confidential unless counsel and the client approve a specific AI workflow.
- Confidential customer, supplier, vendor, or partner contracts.
- Raw financial statements, quality of earnings files, debt schedules, tax materials, and working capital support.
- Employee compensation data, HR files, benefits information, retention plans, and personally identifiable information.
- Board materials, management presentations, investor decks, strategy documents, and non-public forecasts.
- M&A process letters, bids, valuation materials, financing documents, and investment committee memos.
- Source code, product roadmaps, cybersecurity reports, architecture diagrams, trade secrets, and intellectual property files.
- Documents containing material non-public information, privileged legal advice, antitrust-sensitive information, or regulated personal data.
If the team needs to test a prompt, it should use synthetic examples, public documents, or redacted materials. Real transaction data should be processed only in an approved environment with the right contractual, technical, and governance controls.
Clean Teams, Antitrust, MNPI, and Privilege
M&A due diligence can involve legal and regulatory constraints that go beyond ordinary confidentiality. In competitive or regulated transactions, some information may be restricted to clean teams, outside counsel, or designated advisors. DeepSeek workflows should reflect those boundaries instead of giving every user access to every document.
Clean team materials may include competitively sensitive information such as customer-level pricing, margins, supplier terms, pipeline data, product roadmaps, or strategic plans. Antitrust-sensitive information should not be mixed into a general AI workspace unless counsel has approved the access model, user permissions, logging, and output controls.
Deal teams should also protect material non-public information, or MNPI, especially in public-company transactions, minority investments, financing processes, or situations involving listed securities. AI outputs that summarize MNPI should be handled with the same care as the underlying source documents.
Legal privilege is another concern. Uploading privileged legal advice, litigation strategy, or counsel communications into an unapproved AI system may create unnecessary risk. Teams should confirm with counsel before using DeepSeek on privileged or potentially privileged materials.
Best Practices for Getting Started With DeepSeek in M&A Diligence
The best way to adopt DeepSeek is to start narrow, measure quality, and expand only after the team has confidence in the workflow. Do not begin with the entire data room. Start with a defined document type, a clear question, and a review process.
- Pick one high-friction use case. Good starting points include change-of-control review, customer contract summaries, management presentation Q&A, board minute issue extraction, or IT systems inventory.
- Use only approved data. Confirm NDA permissions, client consent, data sensitivity, and security requirements before uploading or indexing documents.
- Create a standard output template. Require source references, exact excerpts, risk categories, confidence levels, and follow-up questions.
- Run a human quality check. Sample outputs against original documents and track false positives, missed issues, and unclear reasoning.
- Keep an audit trail. Preserve prompts, source sets, model settings, reviewer changes, and final approved findings.
- Assign ownership. AI-generated legal findings should go to legal reviewers; financial findings to finance or accounting reviewers; operational findings to integration workstream owners.
- Separate facts from recommendations. A source-backed clause extraction is different from a negotiation recommendation or valuation adjustment.
Once the first workflow is reliable, teams can connect DeepSeek to broader diligence processes: data room indexing, Q&A logs, issue trackers, integration workplans, and synergy dashboards.
How to Measure Output Quality
A DeepSeek workflow should be measured before it becomes part of a live diligence process. The goal is not to prove that the model is perfect. The goal is to understand where it helps, where it misses issues, and where human review must be strongest.
| Quality check | What to measure |
|---|---|
| False positives | Findings that look like issues but are not actually supported by the source documents. |
| False negatives | Material issues the model failed to identify. |
| Source accuracy | Whether the cited document, page, clause, excerpt, or spreadsheet tab actually supports the finding. |
| Sampling review | A human review sample across high-risk, medium-risk, and low-risk outputs. |
| Reviewer sign-off | The named legal, financial, tax, commercial, IT, or HR reviewer who approved or corrected the finding. |
| Audit trail | Prompt version, source set, model settings, reviewer changes, date of review, and final approved output. |
The team should track mistakes in both directions. False positives waste reviewer time, but false negatives are more dangerous because they can hide real issues. High-stakes findings should never move into a diligence report, investment committee memo, board pack, or purchase agreement negotiation without human verification.
Once the first workflow is reliable, teams can connect DeepSeek to broader diligence processes: data room indexing, Q&A logs, issue trackers, integration workplans, and synergy dashboards.
A Practical Operating Model for AI-Assisted Due Diligence
A mature AI-assisted diligence process has three layers. The first is the secure document layer: approved files, clean permissions, version control, and data room indexing. The second is the AI analysis layer: DeepSeek prompts, retrieval settings, structured extraction, summarization, and comparison. The third is the expert review layer: lawyers, accountants, bankers, consultants, operators, and executives validating material findings.
This operating model avoids two common mistakes. The first mistake is treating AI as a toy that analysts use informally with no governance. The second is treating AI as a magic diligence engine that produces final answers. The better view is more practical: DeepSeek can produce organized first drafts, surface likely issues, and reduce manual search time, while experts remain responsible for interpretation and decision-making.
For M&A professionals, that is the real opportunity. AI does not remove the need for diligence. It can make diligence more systematic, more traceable, and easier to connect to the deal thesis. In a competitive process, that can help teams ask sharper questions earlier, identify red flags faster, and build a clearer path from signing to value creation.
FAQ: DeepSeek, AI Due Diligence, and M&A Workflows
Can DeepSeek replace M&A lawyers, bankers, or diligence advisors?
No. DeepSeek can assist with document review, summarization, extraction, comparison, and drafting, but it should not replace professional judgment. Legal conclusions, valuation decisions, accounting treatment, tax advice, negotiation strategy, and board-level recommendations require qualified human experts.
How can DeepSeek help with virtual data room review?
DeepSeek can help organize virtual data room materials by summarizing documents, extracting key terms, grouping issues by workstream, answering source-based questions, and drafting diligence issue lists. The output should include document references and exact excerpts so reviewers can verify every important finding.
Is DeepSeek safe for confidential M&A documents?
It depends on the deployment model, contract terms, data controls, and the sensitivity of the transaction. Teams should not upload confidential deal materials into any AI system until legal, security, privacy, and client stakeholders approve the workflow. For sensitive transactions, enterprise controls, private deployment, or self-hosting may be required.
What are the best first use cases for DeepSeek in due diligence?
The best first use cases are narrow, repeatable, and easy to verify. Examples include contract clause extraction, customer contract summaries, board minute review, management presentation Q&A, IT systems inventory, and synergy assumption tracking. Avoid starting with final legal opinions or valuation recommendations.
How should deal teams reduce hallucination risk?
Require source-grounded answers, exact document excerpts, confidence levels, and human review. Tell DeepSeek not to infer missing terms, and treat unsourced claims as hypotheses. For high-stakes findings, reviewers should check the original document before including the issue in a diligence report, investment committee memo, or purchase agreement negotiation.
What approval is needed before using DeepSeek on data room documents?
Only in an approved environment. Confidential data room documents should not be uploaded into a public or unapproved AI tool. Deal teams should confirm NDA permissions, client approval, legal review, security controls, privacy requirements, data residency, logging, retention, and access permissions before using DeepSeek on live transaction materials.
Does long context make DeepSeek reliable for full data room review?
No. Long context can help DeepSeek process larger document sets, but it does not guarantee complete or accurate diligence findings. Reviewers should still require source references, exact excerpts, confidence levels, sampling checks, and human sign-off before relying on any output.
What should not be uploaded into DeepSeek during M&A diligence?
Unapproved uploads should avoid confidential contracts, raw financials, employee data, board materials, investor materials, source code, customer lists, privileged legal advice, antitrust-sensitive information, and material non-public information. Use synthetic, public, or redacted examples for prompt testing unless the team has approval to process real deal documents.
