Custom CRM · WhatsApp + AIFreelance Project

Built a purpose-built CRM for a digital agency that captures leads from Google Maps, reaches them via official WhatsApp (Twilio + Meta API), and uses AI to suggest replies and standardize templates. The system scaled the lead base by over 500%, with 250 new leads entering the pipeline every day.

250 leads a day. We could never do that manually.

Norte Web Digital
Challenge

Norte Web Digital was growing but had no system to capture, qualify, or contact prospects at scale. Leads were found manually. WhatsApp outreach ran through unofficial channels, which created delivery risk and account-ban exposure. There was no pipeline visibility, no automation, and no way to handle volume without adding headcount.

Solution

A custom CRM built around the agency's sales motion. An automated scraper pulls businesses from Google Maps and other directories, enriches each lead with contact and location data, and routes them into a structured pipeline. Each new lead receives an automated WhatsApp opener sent through the official Meta Business API via Twilio, approved, deliverable, and ban-proof. Inside the chat view, an AI model reads the conversation and suggests a reply with a confidence score. Pre-approved message templates can be sent at one click.
