Kernel TypeScript Sample App - Stagehand

A Stagehand-powered browser automation app that extracts company information from Y Combinator company pages using multiple browsers.

What it does

The company-info-task searches for a startup on Y Combinator's company directory and extracts company information using three separate browser instances:

• Browser 1: Extracts team size (number of employees)
• Browser 2: Extracts company location
• Browser 3: Extracts CEO/founder name

Input

{
  "company": "kernel"  // Startup name to search (optional, defaults to "kernel")
}

Output

{
  "teamSize": "11",        // Team size as shown on YC company page
  "location": "San Francisco, CA",  // Company location
  "ceo": "John Doe"        // CEO or founder name
}
