N8N lead finding & scoring workflow/agent.

Build an advanced n8n workflow to score leads with AI and sync data across Clay, Slack, and Google Sheets

I’m looking for an experienced n8n expert to build a fully automated workflow that integrates Clay, OpenAI, Slack, and Google Sheets.

You’ll be creating an end-to-end system that takes a list of companies, uses Clay to find employees, scores them using GPT based on ICP relevance, and pushes the best contacts into a Google Sheet. After a QA step in Slack, the contacts will be sent to another Clay table for enrichment, with notifications and a final report.

What the workflow needs to do:
1. Receive a JSON payload with:
• A list of companies
• Product/service brief
• Ideal customer persona (ICP)
2. For each company:
• Send data to Clay to run a “Find People” search (via Clay API or webhook)
• Retrieve all employees from the Clay table
3. Use OpenAI to score all employees based on fit with the ICP
4. Select up to 5 best-fit contacts per company
5. Push the results into a Google Sheet (with all metadata)
6. Notify a Slack channel for human QA (via message + link)
7. Upon approval, send the contacts to a second Clay table for enrichment
8. Notify Slack that enrichment has started
9. Once enrichment is complete, post a final Slack message and summary report:
• Total contacts found
• Contacts with valid emails
• Companies with contacts
• Companies without contacts
• Average contacts per company

You should have experience with:
• n8n (intermediate to advanced level)
• Clay (webhooks and API)
• OpenAI / GPT-4 (prompt logic and API integration)
• Slack API (message formatting and interactivity)
• Google Sheets API
• Webhooks and JSON data handling

Deliverables:
• Fully functional and tested n8n JSON workflow
• Setup documentation and instructions
• Guidance on Clay table formatting
• Optional integration support

⸻

Budget: Flexible depending on experience. Fixed price or hourly offers welcome.
