Ari Nakos Built an n8n Agent That Monitors Reddit for Buyer Intent and Emails You Qualified Leads Daily
A workflow that takes your website URL, figures out your industry, searches Reddit for people describing your exact problem, scores each post with AI, and delivers a curated lead list to your inbox — no manual Reddit lurking required.

The Strategy
Reddit is full of people publicly describing their business problems, asking for tool recommendations, and venting about pain points. For B2B companies, SaaS products, and agencies, the people posting in subreddits like r/entrepreneur, r/smallbusiness, or dozens of vertical-specific communities are often the buyers they want to reach. The problem is that monitoring Reddit manually across multiple subreddits is time-consuming, inconsistent, and easy to deprioritize. Ari Nakos built an n8n workflow that automates the entire discovery process. The workflow starts with just your website URL. It analyzes the site to understand your industry and the problems you solve, then uses that context to generate search queries it runs against Reddit. It filters for posts with more than 15 upvotes posted within the past 90 days — cutting out low-signal noise. Each qualifying post goes through an AI evaluation step using OpenRouter and GPT-4.1-mini to assess relevance and summarize what the person is actually asking. Posts that pass the filter are logged in Google Sheets and assembled into a formatted HTML email that arrives in your inbox, ready for outreach. The template is published on n8n's workflow marketplace with a full tutorial. For businesses where the target buyer is actively discussing their problems on Reddit, this system replaces hours of manual subreddit monitoring with a single automated daily or weekly digest.
How It Works
Submit your website URL and email address through the n8n form trigger.
The workflow fetches and analyzes your website content to identify your industry, the problems you solve, and the specific language your buyers use.
Based on that analysis, the AI generates a set of Reddit search queries and identifies relevant subreddits where your target buyers are likely posting.
The workflow queries Reddit via OAuth 2.0 authentication, filtering results to posts with more than 15 upvotes posted within the last 90 days.
Each qualifying post is passed to OpenRouter with GPT-4.1-mini to assess relevance to your business and generate a brief summary of what the poster needs.
Posts that score as highly relevant are logged in Google Sheets: post title, link, subreddit, upvote count, summary, and relevance assessment.
The workflow compiles all results into a professional HTML email and sends it to your inbox as a ready-to-act lead digest.
Results
The template is designed for lead discovery rather than tracked conversions. Ari Nakos published it on the n8n workflow marketplace at $20 with a full tutorial. No verified pipeline or close rate data is documented for this specific workflow. GPT-4.1-mini at $0.05 per 1,000 tokens keeps the AI evaluation cost under a dollar for 100 posts per day. Reddit's API is free within standard rate limits.
Our Take
The elegant part of this system is that it does not require you to know which subreddits to monitor in advance. By starting from your website, the AI infers the right queries for your specific business. That is what makes it generalize: the same workflow adapts to a legal tech SaaS, a roofing agency, or a freelance copywriter without reconfiguration beyond the URL. The AI scoring step matters more than the search step. Any Reddit search returns a mix of relevant and tangential posts. Filtering by engagement (15+ upvotes) removes most of the noise. The LLM evaluation removes most of the rest. What lands in your inbox should be genuinely actionable. The main timing risk is response lag. A Reddit post from 24 hours ago may already have replies from competitors. Running the workflow more frequently — every few hours on high-signal subreddits — reduces that gap. The Reddit API rate limits are generous enough to support more frequent polling without hitting the ceiling.
