A former colleague of mine who attempted a startup and had to go back to a full time job after a year recommended Y Combinator for advice on planning a successful startup.
Y Combinator is an American startup accelerator that was launched in March 2005[1][2][3]. It has been used to launch more than 4,000 companies, including well-known companies such as Airbnb, Coinbase, Cruise, DoorDash, Dropbox, Instacart, Quora, PagerDuty, Reddit, Stripe, and Twitch[1][3]. Y Combinator provides seed funding, mentorship, and resources to early-stage startups to help them grow and succeed. The combined valuation of the top YC companies was more than $600 billion by January 2023[3].
In 2018, Y Combinator announced a new batch of startup schools. After a software glitch, all 15,000 startups that applied to the program were accepted, only to learn a few hours later that they had been rejected. But the ensuing outcry led Y Combinator to change course again and decided over an official blog to accept all those 15,000 companies. Now, every company is accepted to join YC Startup School without any restrictions[3].
In February 2014, Sam Altman became president of Y Combinator. Michael Seibel joined Y Combinator as a part-time partner in January 2013 and later became CEO of the accelerator in 2016. In 2019, Geoff Ralston replaced Altman as president of Y Combinator[3].
