Y Combinator operates as a startup accelerator that provides seed funding, mentorship, and resources to early-stage companies in exchange for equity. Founded by Paul Graham, Jessica Livingston, Robert Morris, and Trevor Blackwell in March 2005, the organization has refined a three-month intensive program that helps founders achieve product-market fit and secure subsequent funding rounds.

Each batch accepts approximately 250-300 companies from over 15,000 applications, representing an acceptance rate below 2%. Selected founders receive $500,000 in funding, intensive mentorship, and access to a network of over 11,000 alumni founders.
