Overview

EXPEDITE automates the entire prospect outreach workflow:

1. Prospect Discovery - Scrapes 4 job board sources to find companies actively hiring
2. Email Enrichment - Uses Hunter.io to find verified email addresses (60-80% success rate)
3. Draft Generation - AI generates personalized emails for each prospect
4. Human Review - All drafts go to Review Queue for user approval before sending
5. Execution - Sends approved emails via Composio integration
6. Tracking - Maintains contact history and engagement metrics

Result: Find and contact 50-100 qualified prospects in minutes, not weeks.

Core Features

1. Intelligent Prospect Discovery

Job Board Scraping

• Scrapes 4 major job board sources simultaneously
• Sources: Hiring.cafe (API), Glassdoor, Monster, Indeed
• Extracts company name, job title, location, and apply URL
• Concurrent scraping for 5-10 second total execution time

How it works:

User Input: "Find VPs of Engineering at Series A startups"
    ↓
System scrapes 4 job boards concurrently
    ↓
Finds 50-100 companies actively hiring for VP Engineering
    ↓
Extracts company and job information
    ↓
Returns structured prospect list

2. Email Enrichment via Hunter.io

Automatic Email Finding

• Integrates with Hunter.io API (500M+ business emails database)
• Finds verified email addresses for prospects
• Validates email confidence (only uses >50% confidence)
• Enriches first 10 prospects per mission to optimize API quota

Success Metrics:

• 60-80% of prospects have verified emails found
• Email validation via MX record checking
• Filters out disposable and invalid emails

Example:

Prospect: John Smith at Acme Corp
    ↓
Hunter.io lookup: acme.com domain
    ↓
Found: john.smith@acme.com (87% confidence)
    ↓
MX validation: PASS
    ↓
Result: john.smith@acme.com (verified)

3. AI-Powered Draft Generation

• Prevents duplicate outreach

Graph Structure:

Person → WORKS_AT → Company
Person → KNOWS → Person
Person → HAS_EMAIL → Email
Company → HIRING_FOR → JobTitle

7. Real-Time Updates via WebSocket

Live Progress Tracking

• Real-time mission progress in chat interface
• Live draft creation notifications
• Instant error alerts
• WebSocket connection for streaming updates

8. LangGraph Agentic Workflow

10-Node Intelligent Workflow
