What is Y Combinator

According to Wikipedia:

Y Combinator is an American seed-stage startup funding firm, started in March 2005. Y Combinator provides seed money, advice, and connections at two 3-month programs per year. In exchange, they take an average of about 6% of the company’s equity.

Compared to other startup funds, Y Combinator itself provides very little money ($14,000 for startups with 1 founder, $17,000 for startups with 2 founders, and $20,000 for those with 3 or more). This reflects co-founder Paul Graham’s theory that between free software, dynamic languages, the web, and Moore’s Law, the cost of founding an information technology startup has greatly decreased. Wired has called Y Combinator a “boot camp for startups” and “the most prestigious program for budding digital entrepreneurs”.

The firm is named after a construct in the theory of functional programming called the “Y combinator“.
