AI-Powered B2B Lead Qualifier with BANT Scoring, Enrichment & Auto-Routing

Automatically qualify, score, and route inbound B2B leads using GPT-4o-mini — no manual review needed.

What This Workflow Does

This workflow turns any inbound lead into a qualified, scored, and routed contact in seconds. It captures leads via webhook (or any trigger like HubSpot, Typeform, or Pipedrive), normalises the data regardless of field naming conventions, enriches it with company intelligence, scores it using the BANT framework via GPT-4o-mini, and routes it into three automated pipelines — all without human intervention.

How It Works

Stage 1 — Lead Entry
Leads enter through a webhook POST endpoint. Swap for any trigger: HubSpot, Pipedrive, Typeform, Google Sheets, or a native CRM node.

Stage 2 — Normalise + AI Field Extraction
Incoming data is mapped to a standard schema regardless of field naming. A secondary GPT-4o-mini extraction step intelligently detects and maps values from any payload structure — even if the source uses completely non-standard field names.

Stage 3 — Enrich
The email domain is analysed to detect personal vs. work email, infer seniority from job title, and derive company information. An optional Hunter.io step adds industry, employee count, and country data.

Stage 4 — AI BANT Scoring
The enriched lead is sent to a structured GPT-4o-mini prompt that returns a score out of 100, a tier label, individual BANT component scores (Budget / Authority / Need / Timeline), a one-sentence reasoning summary, and a recommended next action — all as structured JSON.

Stage 5 — Route by Tier

• 🔥 Hot (score ≥ 70) — Instant Slack alert to #sales-alerts + personalised outreach email via Gmail
• 🌤️ Warm (score 40–69) — Automated soft nurture email via Gmail
• ❄️ Cold (score < 40) — CRM tagging with a 90-day follow-up flag

Stage 6 — Log to Google Sheets
All three tiers are logged to a single Google Spreadsheet with dynamic tab routing (Hot Leads / Warm Leads / Cold Leads).

Key Features

• Works with any lead source — web forms, CRMs, Typeform, HubSpot, Pipedrive, or raw HTTP POST
• AI field extraction handles messy or non-standard payloads automatically
• BANT scoring is fully customisable via the system prompt (adjust weights, thresholds, and tier boundaries)
• Hunter.io enrichment is optional — the workflow degrades gracefully without it
• All three tiers log to a single Google Sheet with dynamic tab routing
• Easily swap Gmail for any email node; swap Google Sheets for Airtable, HubSpot, or any CRM
