Marketing automation: building an AI lead scoring system for B2B sales

AI Automation B2B Lead Generation B2B Marketing CRM Marketing Automation n8n Sales

Use case

In B2B sales and marketing, high-value leads are identified too late and miss the right salesperson, leading to lost sales opportunities and revenue leakage.
➡️ I built an AI-powered marketing automation system that automatically detects high-potential leads through intelligent scoring and routes them to the right sales rep within 15 minutes using CRM integration and workflow automation.

 

Solution: End-to-end lead management automation

  • Trigger: Lead enters from a web form, contact list, trade fair registration, LinkedIn campaign, or other B2B lead generation source.
  • Enrichment: Automatically add company data (firmographics), industry sector, company size, geographic location, decision-maker contact details, and verified email addresses using API integrations (Clearbit, Hunter.io, Apollo.io).
  • AI Lead Scoring: Apply predictive lead scoring algorithm based on ideal customer profile (ICP), behavioral signals, and fit with target market segments.
  • Smart Assignment: Automatically route qualified leads to the appropriate salesperson using territory mapping, industry expertise matching, and workload balancing logic.
  • Instant Alert & Sales Enablement: Send real-time notification via Slack/email with enriched lead intelligence brief, personalized outreach script, and recommended next actions.

Tech Stack: n8n, Google Sheets, CRM (HubSpot/Salesforce), LLM APIs (Mistral AI), search APIs, data enrichment tools.

 

Measurable results & business impact

  • + 50% increase in lead engagement rate → more qualified conversations started with decision-makers
  • + 23% higher email reply rate → improved conversion from lead to sales meeting
  • 100% lead data enrichment accuracy → all leads validated before entering CRM pipeline
  • 15-minute average response time → faster than industry standard (2-24 hours)
  • Zero manual data entry → sales team focused on selling, not admin work
