FAQ

How current is the data? The scraper reads the live Algolia index that powers ycombinator.com/companies. It's the same data users see on the website, refreshed whenever YC updates their directory (typically within hours of a new batch announcement).

Does it include stealth companies? No. Only companies marked ycdc_public in the YC index are accessible. Stealth-mode startups are hidden.

Can I get all batches at once? Yes — omit the batches filter to scrape all 6,300+ companies across every batch from 2005 to present.

What are "top companies"? isTopCompany: true is a YC designation for their highest-impact alumni — roughly the top 5–10% by outcome. Includes companies like Airbnb, Stripe, DoorDash, Coinbase, etc.
