Y Combinator Founder Directory Search

omnial/search-founders

Search the public Y Combinator founder directory by a founder's name or a company name. Each match returns the founder's name, current company and title, the YC batch(es) they went through, their industry tags, region, and a profile photo URL. Per the vendor's own documentation, a blank query returns the full directory, page by page.
