Building MightyScrapper: Automated Lead Generation SaaS
How I built a powerful, fully automated lead generation platform that scrapes Google Maps, extracts business data, and delivers enriched leads with contact information — all from publicly available data.
Visit mightyscrapper.comThe Challenge
Lead generation is time-consuming and expensive. Businesses need qualified leads with accurate contact information, but manual research takes hours and most tools provide incomplete data or require multiple subscriptions.
I identified an opportunity to build an all-in-one automated lead generation platform that could scrape Google Maps business listings, extract detailed information, and enrich it with contact data from websites — all legally sourced from publicly available information.
The Goal
Build a powerful SaaS platform that automates the entire lead generation workflow: search by keyword and location, scrape business data from Google Maps, extract contact information from websites, and deliver enriched leads in minutes — not hours.
Core Features
Google Maps Scraping
Search any keyword + location to extract business listings with name, address, phone, website, ratings, and more.
Website Scraping
Automatically visit business websites to extract owner names, emails, social media links, and additional contact info.
Email Discovery
Find verified email addresses from websites, contact pages, and publicly available sources.
Data Enrichment
Enhance raw data with additional fields: industry classification, social profiles, employee count estimates.
Bulk Processing
Process thousands of leads simultaneously with parallel scraping and intelligent rate limiting.
Export & Integration
Export to CSV, Excel, or integrate directly with CRMs via API webhooks.
Technology Stack
Development Journey
Planning & Architecture
Designed system architecture, selected tech stack, and planned scraping workflow. Set up development environment and project structure.
Core Scraping Engine
Built Google Maps scraper using Puppeteer. Implemented headless browser automation, anti-bot evasion, and data extraction logic.
Website Enrichment
Added website scraping module. Created email extraction algorithms, contact page parsers, and social media link discovery.
Frontend & Dashboard
Built React dashboard with real-time scraping progress, data preview, filtering, and export functionality. Integrated payment system.
Launch & Optimization
Deployed to production VPS. Implemented Redis queue for scalability. Added bulk processing, API webhooks, and launched to first customers.
Technical Highlights
- Anti-Detection: Implemented browser fingerprinting evasion, random delays, and proxy rotation to avoid blocks
- Scalable Architecture: Built with Redis queue system to handle thousands of concurrent scraping jobs
- Smart Parsing: Created regex patterns and NLP techniques to extract emails, names, and phone numbers from unstructured website content
- Error Handling: Robust retry logic, timeout management, and graceful degradation when data isn't available
- Legal Compliance: Only scrapes publicly available data, respects robots.txt, implements rate limiting
