n8n B2B Lead Gen Automation: Geoapify, Airtable, Groq & Gmail

Geo-targeted B2B lead generation + daily research and outreach—fully automated in n8n

This n8n workflow automates B2B lead generation using Geoapify, stores and deduplicates leads in Airtable, runs daily competitive research with a LangChain agent (Groq/Mistral + Perplexity + Tavily), and triggers daily outreach via Vapi calls and AI-drafted emails through Gmail.

What this workflow does

• Captures lead search inputs from an n8n form: industry, city, country, and an optional keyword.
• Finds local businesses with Geoapify Places API by geocoding the city and searching for up to 20 matching businesses near the location.
• Extracts business details (name, phone, website, email, address, categories) and checks Airtable for duplicates using the phone number.
• Creates new leads only in Airtable for non-duplicates, skipping any leads already present.
• Runs daily lead research by fetching “New” leads from Airtable and using a LangChain research agent (Groq/Mistral) with Perplexity and Tavily tools to compile competitor, review, decision-maker, and pain-point information.
• Updates Airtable records with parsed JSON research fields, sets Status to “Researched”, and logs the research date.
• Performs daily outreach for “Researched” leads: staggers processing, places outbound calls via Vapi, and logs call status/contact date back to Airtable.
• Sends AI-drafted cold emails in parallel using a Groq/Mistral LLM and Gmail delivery.

Use cases

• SaaS operators generating geo-targeted B2B prospects and keeping CRM-style data clean in Airtable.
• Automation engineers running a repeatable n8n pipeline for daily research + outreach at scale.
• Teams validating new verticals by combining Geoapify discovery with Perplexity/Tavily intelligence and immediate follow-up.
