AI Lead Qualification Agent
Tools: n8n, Claude AI, Serper.dev, Google Sheets, Gmail
Overview
Overview
An AI-powered workflow that automatically qualifies inbound leads for a marketing agency.
When a prospect submits a contact form, the agent validates their company domain (format and reachability check), searches the web for company information via Serper.dev API, and sends the data to Claude AI for scoring and analysis.
Claude returns a structured qualification report: score (1-10), company summary, strengths, concerns, and recommendation. The report is saved to Google Sheets and emailed to the team.
Who this is for: Marketing agencies, B2B service providers, and sales teams who receive inbound leads via web forms and need fast, consistent qualification without manual research.
Demonstrated using BrightReach Marketing, a fictional boutique digital marketing agency specializing in paid advertising and content strategy for e-commerce brands.
How It Works
How It Works
1. A prospect fills in a contact form with their name, email, company website, marketing budget, and what they're looking for
2. The workflow validates the company domain format (must contain a dot, no spaces)
3. The domain is checked for reachability (HTTP request to verify the site exists)
4. If valid and reachable, Serper.dev runs two web searches: general company info and marketing-specific info
5. All data (form submission + web search results) is sent to Claude AI
6. Claude evaluates the lead against the ideal client profile and returns a JSON qualification report
7. The report is parsed and saved to Google Sheets (contact data + qualification)
8. An email notification is sent to the team with the full report
9. The submitter sees a confirmation (in production) or the qualification report (in demo mode)
Workflow overview: incoming leads are automatically researched, qualified by AI, and saved with an email alert to the team

Try it yourself: submit a fictional lead and see the AI qualification report.
Demo mode is enabled: the qualification report is shown on the confirmation page. In production, only the agency team would see the report.
