Y Combinator

Y Combinator is a startup accelerator based in Mountain View, California, founded in 2005. It has pioneered a new funding model for early-stage startups by investing a modest amount of capital, typically around $150,000, in a large number of companies twice a year. Over a three-month program, Y Combinator collaborates closely with these startups to prepare them for investor pitches and enhance their business strategies. Each funding cycle concludes with Demo Day, where startups present to an exclusive audience of investors. Y Combinator focuses on various sectors, including business software, education, healthcare, and financial technology, among others. In addition to initial funding, it offers ongoing support through its extensive alumni network. Since its inception, Y Combinator has funded over 630 startups, contributing significantly to the entrepreneurial ecosystem in Silicon Valley and beyond.
