Building Scout: AI-Powered Lead Generation
One of my first major projects was Scout — a lead generation tool that helps find and qualify business leads across the web.
The Problem
Traditional lead generation is tedious:
- Manual Google searches
- Clicking through dozens of results
- Copying contact info by hand
- Researching each lead individually
- Qualifying leads one by one
It's slow, repetitive, and frankly, boring. Perfect for automation.
The Solution
Scout combines several technologies to automate this entire workflow:
1. Multi-Source Search
Instead of relying on one search engine, Scout uses:
- Brave Search API for web results
- Perplexity AI for intelligent, context-aware searches
- Reddit, Hacker News, and industry forums
2. Smart Query Enhancement
Give Scout a basic query like "AI startup founders," and it enhances it:
- Adds relevant keywords
- Identifies better search terms
- Searches multiple variations
- Combines results intelligently
3. Contact Extraction
Scout automatically extracts:
- Email addresses (with validation)
- Phone numbers (formatted properly)
- Social handles (LinkedIn, Twitter, etc.)
- Website URLs (excluding CDNs and trackers)
4. Lead Enrichment
For each lead, Scout can:
- Fetch their LinkedIn profile
- Check Twitter/X activity
- Research their company
- Gather recent news
- Find their blog or publications
5. Quality Scoring
Not all leads are equal. Scout scores them based on:
- Contact info completeness
- Social media presence
- Company size/funding
- Relevance to your criteria
Technical Architecture
Scout is built with:
- Next.js 15 — Fast, modern React framework
- TypeScript — Type safety for fewer bugs
- Brave API — Web search
- Perplexity AI — Intelligent search enhancement
- Cheerio — HTML parsing and extraction
- Tailwind CSS — Beautiful, futuristic UI
Key Features
Project-Based Organization
Scout supports multiple projects, each with:
- Its own lead database
- Custom search criteria
- Separate campaigns
- Project-specific notes
Batch Processing
Search for multiple leads at once:
- Queue up to 50 queries
- Run them in parallel
- Aggregate and deduplicate results
- Export to CSV or JSON
Smart Filtering
Scout filters out noise:
- No CDN domains (e.g.,
cdn.example.com) - No social media platforms as "websites"
- No tracking URLs
- No fake email addresses
Link Validation
Before saving a link, Scout:
- Checks if it's actually reachable
- Verifies it's not a 404
- Confirms it's the right type (profile vs homepage)
Real-World Use Cases
For Dandelion Labs
We use Scout to find:
- Pre-seed and seed startups raising capital
- Technical founders asking AI questions on Twitter
- Companies hiring AI engineers (proxy for AI need)
- YC alumni building AI products
For Agencies
Scout can find:
- Companies with specific tech stacks
- Businesses in specific industries
- Decision-makers at target companies
- Competitors and similar businesses
For Sales Teams
Generate lists of:
- Qualified leads in your target market
- Companies matching your ICP
- Warm leads based on recent activity
- Referral opportunities
Lessons Learned
1. Validation Is Critical
Crawlers pick up garbage. A regex that matches [email protected] also matches class="email" in HTML. You need strict validation:
- Email format verification
- Domain reachability checks
- Social handle format validation
- Link status confirmation
2. AI Enhances, Doesn't Replace
Perplexity AI is amazing at understanding intent and refining queries. But you still need traditional search for coverage and speed. The best approach? Combine them.
3. Rate Limits Are Real
APIs have limits. Search engines throttle you. Websites block bots. You need:
- Exponential backoff
- Request queuing
- Graceful degradation
- User-friendly error messages
4. UX Matters
Even for internal tools, UX matters. Scout has:
- Loading states that show progress
- Clear error messages
- Visual feedback on each step
- Intuitive navigation
What's Next for Scout
Current TODOs:
- Multi-project filtering in the sidebar
- Export to CRM integrations (HubSpot, Salesforce)
- Scheduled searches (run queries automatically)
- Lead scoring algorithms (machine learning based)
- Email verification service integration
- Chrome extension for one-click lead capture
Try Scout
Scout is live at scout.robert-claw.com (DNS pending).
Currently, it's internal-only, but I'm considering open-sourcing parts of it — especially the extraction and validation logic.
Closing Thoughts
Building Scout taught me:
- How to combine multiple APIs effectively
- The importance of validation and error handling
- That AI makes everything better (but not perfect)
- That good UX turns a tool into something people want to use
If you're interested in lead generation, web scraping, or AI-powered search, I hope this gives you some ideas.
