🔧 Workflow

Runs automatically every day at midnight: First, it scrapes users on GitHub with active commits in the last 7 days for employer-specified tech stacks (such as CUDA optimization, multimodal LLM fine-tuning), extracts their code repository star counts, contribution dimensions, and tech stack tags, and stores them in a vector database; next, it performs semantic matching and scoring with the employer's JD, selects the Top 20 candidates, and calls the LLM to generate personalized headhunting messages referencing their specific open-source project contributions; human headhunters review all content within 10 minutes, and after confirming there are no factual errors, send batch direct messages via LinkedIn Sales Navigator while simultaneously logging the candidate response status.

🛠 Setup Requirements

Requires basic Python scraping skills, familiarity with the GitHub REST API and LinkedIn direct messaging rules; uses n8n for workflow orchestration, Pinecone for long-term candidate profiling, and GPT-4 to generate headhunting message content; building the complete workflow for the first time takes about 12 working days, with API debugging accounting for 5 days and headhunting message template tuning accounting for 3 days.

💰 Revenue

① B-end employer headhunting commission (main revenue): Employers settle commissions at 18%-22% of the candidate's first-year annual salary after successful onboarding, yielding 20,000 to 50,000 RMB per placement. Successfully placing 1-2 candidates per month generates a monthly revenue of 22,000 to 100,000 RMB. Calculated based on just 1 placement, it equals approximately 22,000 RMB, accounting for about 90% of monthly revenue (a figure derived by the card itself using the commission formula, case-based, without third-party verification); ② Multi-client concurrent incremental revenue: After accumulating 3 or more stable B-end clients, monthly revenue can exceed 30,000 RMB (according to the card's claim), with payment still tied to onboarding results, and percentage figures missing; ③ Technical talent profile matching subscription: Packaging GitHub activity and code quality scores to sell to enterprises per HR seat or monthly. The benchmarking project Auto-JobHunter has gained over 1,200 GitHub stars, with a tested headhunting message response rate of 21% (a case study paraphrased by the card, unverified independently). The subscription unit price and percentage breakdown are not provided; ④ Opportunity item - External authorization of multi-platform job collection and delivery tools: Charged via enterprise annual fees or call volume, with no searchable data currently available for price and quantity, and the percentage breakdown is also left blank.

💸 Cost

Fixed expenses are roughly 850-1,400 RMB per month: OpenAI API calls cost about 400-800 RMB/month, and LinkedIn Sales Navigator advanced account subscription costs about 600 RMB/month; candidate profile storage can use Pinecone's free tier, so no extra payment is necessary for the initial stage under 1,000 profiles.

⏱ Time Investment

2 to 3 hours daily reviewing headhunting message content and following up on candidate responses.

🚀 Getting Started

The first step is to choose a technical vertical in which you have cognitive expertise (such as LLM inference optimization, frontend framework development), manually screen 10 highly active technical talents on GitHub, and test the response rate of personalized headhunting messages. If the response rate is higher than 15%, the feasibility is validated; then use n8n to build the automated matching and generation workflow, partner with 2-3 startups that have just completed Series A financing and are urgently recruiting technical backbones, agree on a commission model paid upon onboarding success, and run through a single minimum viable transaction before scaling up.

🔑 Keys to Success

✅ Headhunting messages must cite specific code commits and open-source project details of candidates to stand out from a flood of direct messages.
✅ Prioritize serving startups that have just completed financing and are urgently recruiting technical backbones, as they have the highest acceptance of individual headhunters.
✅ The GitHub activity and code quality scoring model is the core barrier, directly determining matching precision and response rate.
✅ Strictly control the sending frequency of headhunting messages, keeping it to no more than 30 sends per account per day, and ensure content is manually reviewed to avoid triggering LinkedIn rate limits or account bans while guaranteeing content quality.

⚠️ 风险

⚠️ High-frequency automated sending of direct messages on LinkedIn may trigger rate limits or even account bans, requiring control over sending frequency and content diversity.
⚠️ Large-scale crawling of user data from GitHub may trigger anti-scraping mechanisms and API call limits.
⚠️ If candidates discover that headhunting messages are automatically generated, they may develop aversion, requiring manual review to safeguard quality.
⚠️ If a candidate resigns shortly after onboarding, there may be a risk of B-end clients demanding a refund of the commission.

📌 Real Cases

📌 Hewa released the headhunting industry's AI-native Agent 'Domi', automating the traditional sourcing workflow, having served over 200 tech enterprises and boosting talent matching efficiency by 3x.
📌 The open-source project Auto-JobHunter has gained over 1,200 GitHub stars, with a tested technical talent headhunting message response rate of 21%, a 4x improvement over traditional headhunter direct messages.
📌 The vertical headhunter team 'Technical Black House' used a similar AI headhunting system to recommend an average of 12 technical talents per month in 2025, stabilizing headhunting commission monthly revenue above 25,000 RMB.
