Free dataset: 50K YC company descriptions, cleaned

YC Companies Dataset — Free Download

I've compiled and cleaned a dataset of 50,000+ Y Combinator company descriptions from public sources.

Fields included:

• Company name
• Batch (W21, S22, etc.)
• One-line description
• Long description
• Industry tags
• Status (active/dead/acquired)
• Website URL
• Founding year

Format

Available as CSV and JSON. Data is deduplicated and normalized.

Usage ideas

• Train models on startup descriptions
• Market analysis
• Competitive research
• Build a YC company search engine

Last updated: February 2026. I'll keep refreshing it quarterly.
