AI Lead Nurturing Bot — n8n + OpenAI + WhatsApp Business API
Stop losing warm leads to slow follow-ups. Our bot captures every submission from your Typeform or Tally form, fires an n8n workflow, and sends a hyper-personalised WhatsApp message written by GPT-4o — all within seconds, around the clock.
Build My Lead BotWhat We Build
A fully automated lead nurturing funnel that reacts to every new lead in real time. No manual outreach, no copy-paste templates — just intelligent, contextual conversations that move prospects down your pipeline.
Form-Triggered Intake (Typeform / Tally)
We configure your lead capture form to send a webhook the moment someone submits. Custom fields — name, business type, budget, goal — are passed directly into the n8n workflow as structured data used to personalise every message.
n8n Workflow Orchestration
n8n acts as the brain. It receives the webhook, enriches lead data (CRM lookup, deduplication), routes the message to OpenAI with a crafted prompt, and triggers WhatsApp delivery. We build multi-branch logic for different lead segments or services.
OpenAI Personalisation Engine
GPT-4o receives the lead's answers and writes a message that feels human — referencing their specific pain points, industry, and goals. No generic templates. Each reply is unique, on-brand, and optimised for reply rate.
WhatsApp Business API Delivery
We integrate with an official WhatsApp Business Solution Provider (BSP) — such as 360dialog, WATI, or Twilio — to send approved message templates and free-form replies. Delivery receipts are logged back into n8n for tracking.
CRM & Follow-Up Sequences
We connect the bot to your CRM (HubSpot, Pipedrive, GoHighLevel) and build timed follow-up sequences — Day 1, Day 3, Day 7 — with AI-written messages based on whether the lead replied or went silent.
How We Build It
1. Discovery & Prompt Strategy
We map your sales process, define lead segments, and engineer the OpenAI system prompt to match your tone and conversion goals.
2. Form & Webhook Setup
Configure Typeform or Tally with the right fields, set up the n8n webhook endpoint, and test the data payload end-to-end.
3. n8n Workflow Build
Build the full workflow: data parsing, OpenAI API call, response formatting, error handling, and WhatsApp delivery node.
4. WhatsApp BSP Integration
Connect your WhatsApp Business account, get template messages approved by Meta, and configure the API credentials securely.
5. Testing, Handoff & Training
Run end-to-end tests with real leads, record a walkthrough Loom, and hand off with full documentation so your team can maintain it.
