🔧 Workflow

Upon receiving an M&A due diligence project, batch import hundreds of the target company's contracts into a locally deployed contract analysis workflow. The AI extracts risk points such as change of control, non-assignment clauses, exclusivity clauses, liabilities for breach of contract, terms, and termination conditions for each contract, and outputs a structured checklist. Then, humans review high-risk clauses one by one, write a due diligence issue list, and deliver it to the law firm or acquirer according to the project. The execution cycle for each project is 5 to 10 days, with 2 to 4 hours invested daily in verification work. During non-project periods, continuously supplement the template library and prompt library to form a compounding asset that becomes more accurate with use.

🛠 Setup Requirements

Requires basic legal knowledge or collaboration with a practicing lawyer for gatekeeping, preferably with a law firm or corporate legal background. Technically, no coding is required, but you must know how to build prompt template libraries and use private environments like Priv or localized deployment to process client contracts to meet confidentiality requirements. Refining the templates in the early stage takes about two weeks, including organizing more than 20 desensitized contract samples to run through the entire process. The first order can start from subcontracting and free trial reviews from acquainted law firms or boutique M&A advisors.

🧰 Toolchain

🔧 Claude or GPT Enterprise API (batch extraction of contract clauses and risk classification)
🔧 Dify or privately deployed large model workflows (processing client contracts in a confidential environment)
🔧 Feishu Multidimensional Table or Notion (structured presentation and delivery of due diligence issue lists)
🔧 Adobe Acrobat or Textin OCR/Scanning (turning historical paper contract PDFs into text)
🔧 WeChat Work or encrypted file transfer tools (securely docking contract documents with law firms)

💰 Revenue

① Law firm/acquirer M&A due diligence project service fee (main revenue): law firms or acquirers pay a one-time fee per project, 15,000-40,000 RMB per project × 1-2 projects per month = 15,000-80,000 RMB monthly income (approximate net monthly increase of 30,000-60,000 RMB), accounting for about 100% of monthly income (according to the case study, independently unverified; as of 2026); ② Routine contract review monthly subscription: SMEs subscribe to review services monthly or per contract, with large model API costs of 300-800 RMB per month (subscription pricing and scale of subscribers are undisclosed, contribution cannot be split for now); ③ Revenue sharing from joint delivery with practicing lawyers: commission per project, with no public data on commission ratios, order volume, or weight in total revenue; ④ Opportunity item — Due diligence clause extraction template library licensing: charging law firms an annual licensing fee, with the annual licensing price undisclosed and scale unspecified.

💸 Cost

Mainly large model API invocation fees, ranging from 300 to 800 RMB per month; if private deployment is used, additional server costs of about 500 RMB per month apply, and office software amortization is about 100 RMB per month.

⏱ Time Investment

3 to 5 hours daily during project periods, and about 5 hours weekly during non-project periods for maintaining templates, updating prompt libraries, and operating customer acquisition channels.

🚀 Getting Started

Step 1: Download public contract samples to run through the extraction templates, turning standard due diligence clauses such as change of control and non-assignment into reusable prompt libraries; Step 2: Contact a local boutique law firm or M&A financial advisor, using 30 free trial contract reviews to build cases and delivery reputation in exchange for the first paid project.

🔑 Keys to Success

✅ Template library compounding: Clause extraction prompts and risk checklists accumulate and become more comprehensive, leading to continuous decreases in marginal time and costs for subsequent projects
✅ Humans as referees: High-risk clauses must be manually reviewed and signed off on; AI only handles preliminary screening, and delivery quality relies on dual-track gatekeeping
✅ Confidentiality and compliance are hard thresholds: Private deployment, non-disclosure agreements, and data desensitization processes are prerequisites for winning law firm orders
✅ Binding professional endorsement: Jointly signed delivery with practicing lawyers avoids qualification risks and increases average order value

⚠️ 风险

⚠️ Client contracts involve commercial secrets; data leaks will lead to legal liabilities and reputation collapse
⚠️ Independently issuing legal opinions without practicing lawyer qualifications carries compliance risks; partnering with practicing lawyers for delivery is recommended
⚠️ The M&A market has long cycles and high volatility; off-season orders may drop sharply, requiring routine contract review business to smooth out income

📌 Real Cases

📌 A major Japanese law firm launched an AI contract analysis (legal DD) service in November 2025, where lawyer-supervised AI automatically extracts key clauses such as change of control and non-assignment in M&A due diligence, validating that this scenario has been productized by top institutions
📌 Ivo, a contract review AI company founded by former U.S. lawyer Min-Kyu Jung, completed a $25.6 million financing round in February 2025, specializing in automated contract review for legal workflows
📌 In domestic enterprise-level contract review scenarios, Agent solutions from Laiye Technology have been broken down into digital legal employee cases, indicating that contract review intelligent agents in 2026 are moving from text extraction to end-to-end delivery
