The following notable startups have completed the Y Combinator Accelerator program.
In 2015, Mike Isaac described Y Combinator as: "Y Combinator accepts batches of start-ups twice a year in a semester-like system and gives them money, advice and access to a vast network of start-up founders and technologists who can advise them." Since Fall 2024, Y Combinator has accepted four batches of startups per year.
