Your sales team gets 200 new leads per week. Each lead arrives as a name, email, and maybe a company name. Before a rep can make a meaningful outreach, they need to research the company's size, tech stack, recent news, and potential fit. That research takes 10-15 minutes per lead -- over 30 hours per week spent on Google and LinkedIn instead of selling.
Lead enrichment automates this research. CrawlForge scrapes public business data from company websites, social profiles, and news sources to build a complete lead profile in seconds. This guide shows you how to build a lead enrichment engine that processes 200+ leads per hour.

What Is Lead Enrichment
Lead enrichment is the process of supplementing basic lead data (name, email, company) with additional information that helps sales teams qualify and prioritize prospects. Enriched data typically includes:
| Data Point | Source | Sales Value |
|---|---|---|
| Company size | About/team page | Qualification |
| Industry | Website content | Segmentation |
| Tech stack | Page source analysis | Product fit |
| Recent news | Search results | Conversation starters |
| Funding status | Press releases | Budget signals |
| Content topics | Blog analysis | Pain point mapping |
What is lead enrichment? It is the automated process of appending business intelligence data to raw lead records, transforming a basic email address into a comprehensive prospect profile that sales teams can act on immediately.
CrawlForge is best for lead enrichment teams that need real-time data from company websites, because unlike database providers (ZoomInfo, Clearbit) that can be weeks out of date, CrawlForge scrapes live pages for current information.
Architecture Overview
The enrichment engine uses five CrawlForge tools:
| Component | Tool | Credits | Purpose |
|---|---|---|---|
| Website content | extract_content | 2 | Company description and positioning |
| Metadata | extract_metadata | 1 | Title, description, social profiles |
| Page source | fetch_url | 1 | Detect technologies from HTML |
| Company research | search_web | 5 | Recent news, funding, social |
| Analysis | analyze_content | 3 | Industry classification and topics |
Step 1: Company Website Analysis
Start by extracting core company information from their website.
Step 2: Technology Stack Detection
Detect the technologies a company uses by analyzing their website's HTML source and headers.
This detection runs on a single fetch_url call (1 credit) -- making it extremely cost-efficient for bulk lead enrichment.
Step 3: Company Intelligence Gathering
Use search_web to find recent news, funding announcements, and market context.
Step 4: Build the Enrichment Pipeline
Combine all enrichment steps into a single pipeline that processes leads in bulk.

Results and Benefits
A lead enrichment engine with CrawlForge delivers:
- Speed: Enrich a lead in 15-30 seconds instead of 10-15 minutes
- Consistency: Every lead gets the same depth of research
- Prioritization: Quality scores let reps focus on the highest-value leads first
- Cost efficiency: $0.07-0.13 per lead vs. $0.50-2.00 for database providers
Compared to enrichment database providers like Clearbit ($99/mo for 1,000 lookups) or ZoomInfo ($15,000+/year), CrawlForge delivers current data at a fraction of the cost. The trade-off is that CrawlForge scrapes live data (always current) while databases provide pre-structured fields (less processing needed).
Frequently Asked Questions
How accurate is tech stack detection from HTML?
HTML-based detection catches the most popular tools with high accuracy (90%+) for client-side technologies. Server-side technologies are harder to detect. For comprehensive detection, combine CrawlForge with BuiltWith or Wappalyzer data.
Can I enrich leads from personal email domains?
Leads from gmail.com or outlook.com do not have company domains to analyze. For these, use search_web to find their professional profiles based on name. This costs 5 credits per lookup instead of the full 14-credit pipeline.
How do I handle rate limiting when enriching in bulk?
CrawlForge's batch_scrape tool handles rate limiting automatically. For individual calls, add a 500ms delay between requests to the same domain. Process different domains in parallel for maximum throughput.
Enrich your first 50 leads free. Start with 1,000 credits -- enough to fully enrich 70+ leads with no credit card required.
