🔧 Workflow

Every morning at midnight, the system automatically pulls all new comments containing target keywords from designated Subreddits over the past day. First, Qianwen 3.8 performs an initial screening of the commenters' identities, pain point intensity, and product fit. Next, humans conduct a secondary review on the top 30% of high-intent leads. Once confirmed free of violation risks, Kimi K3 is triggered to generate personalized direct message content with specific details. After final human confirmation, messages are batched and sent. Inputs include the target Subreddit list, product keywords, and DM template rules; outputs include 20 to 50 high-intent DMs per day, a lead conversion dashboard, and user response rate statistics.

🛠 Setup Requirements

Requires basic prompt engineering skills and proficiency in workflow orchestration using Dify or n8n; deep programming skills are not needed. Hardware is limited to an ordinary home computer. Uses Apify's Reddit scraper API to pull public comment data, Supabase for user and lead data storage, and Stripe for global subscription payment processing. A single person can complete MVP development and launch for testing within 2 to 3 weeks, with subsequent iterations requiring only a small amount of time each week to optimize the intent classification model.

💰 Revenue

① Small-to-medium cross-border SaaS team monthly subscriptions (primary revenue): SaaS teams pay a monthly subscription fee per account, with an average unit price of about $80/month × about 40 companies = $3,200/month, accounting for about 80% of monthly revenue (calculated based on unit price and customer count from case materials, not independently verified); ② One-time lead bundle sales: One-time charges to cross-border teams and service providers per package, accounting for the remaining ~20%, about $800/month. Package sizes and bundle prices are undisclosed, accounting for ~20% (also calculated based on data in the notes); ③ Annual subscription renewals: Long-term clients prepay annually, with stable annualized revenue reaching over $48,000 and a repurchase rate maintained around 65% (taken from the notes); annual discounts and the exact revenue share of this segment are undisclosed; ④ Opportunity item - over-quota lead expedited fee: Expedited fees charged per instance for leads exceeding the monthly quota. Referring to similar lead ticket markets where users are willing to pay a 30-50 RMB premium for 'expedited processing' (case statement, not independently verified), the exact revenue from expedited fees has no figures yet, and its share is also unspecified.

💸 Cost

Large language model API call costs total approximately 200 to 500 RMB/month, Apify Reddit scraper credits cost about $20/month, Supabase free tier can support data storage for the initial 1,000 users, domain name and basic server costs are about 50 RMB/month, and total initial monthly operating costs are under 600 RMB.

⏱ Time Investment

About 2 to 3 hours per day monitoring the pipeline, tuning prompts, and handling paid user feedback.

🚀 Getting Started

Step one: Download the open-source BizRadar code framework from GitHub, complete a minimum functional test of Reddit comment monitoring locally, manually run data for 2 weeks in 1 vertical, niche Subreddit (such as SaaS startup-related boards), and verify that both intent classification accuracy and DM response rates meet expectations. Step two: Package it into a standardized SaaS product using Dify, attach Stripe payment links, and publish/promote it on platforms like relevant Reddit boards and Product Hunt. Acquire the first 10 paid test users before iterating on features.

🔑 Keys to Success

✅ Comment intent classification accuracy must reach 85% or higher for people to reply to DMs
✅ DM templates must strictly comply with Reddit platform policies to prevent account bans
✅ The conversion path from the open-source version to the paid version must have clear tutorial documentation
✅ A manual review intermediate step must be set up; fully automated direct message sending easily triggers Reddit's spam detection mechanisms

⚠️ 风险

⚠️ Reddit's official API policies tightened in 2024 and may face further restrictions in 2026, leading to underlying infrastructure failure
⚠️ Excessively low unit prices invite price wars, putting pressure on MRR and renewal rates
⚠️ Reddit users have an extremely low tolerance for untargeted automated DMs. If content is homogenized and lacks personalized details, it will trigger a large number of reports, leading to the banning of sending accounts and even affecting subsequent access from the IP range.
