Overview

Automate Pro is a lead gatekeeper for an agency drowning in inbound forms. Before it shipped, a human read every submission, scored it by gut feel, and either escalated it to sales or filed it away. The bottleneck was the human.

After: an n8n pipeline scores every lead the moment it lands, routes the top 20% straight into Slack with full context, and quietly drops the bottom 80% into a Sheets nurture queue. The same agency now spends those 20 hours on actual sales calls.

How it works

Form → React frontend → n8n webhook → Gemini scoring → Slack | Sheets

The React frontend captures lead data with a dynamic form and behavioral tracking, what fields they edited, how long they spent on each posts to an n8n webhook. n8n hands the payload to Google Gemini 2.5 Flash with a scoring prompt that weighs project scope, budget signals, and stated urgency, returning a 0–10 quality score plus a one line rationale.

A router node branches on the score. 8 and up: Slack message to the sales channel with the lead, the rationale, and a click-to-respond button. Below 8: appended to a tiered Google Sheet that feeds the nurture sequence later.

What I learned

  • The model isn’t the product. The pipeline is. The Gemini call is 10% of the work; the other 90% is wiring it cleanly into systems the team already trusts.
  • Behavioral signals from the form (dwell time, edits) turned out to be a better quality signal than the form answers. Users overstate budget and understate timeline. They don’t fake how long they spent.
  • Gemini 2.5 Flash is shockingly cost-effective for high-frequency classification work like this.

Reflection

This is the project I point at when someone asks “what does AI actually do for a small business.” Not magic. Just a tireless reader sitting between the inbox and the team.
