Y Combinator is an American seed-stage startup funding firm, started in 2005 by Paul Graham, Robert Morris, Trevor Blackwell, and Jessica Livingston. 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 provides very little money ($17,000 for startups with 2 founders and $20,000 for those with 3 or more). This reflects Graham’s theory that between free software, dynamic languages, the web, and Moore’s Law, the cost of founding a startup has greatly decreased.
Y Combinator was started after Graham gave a talk at his alma mater, Harvard (where he earned a PhD in Computer Science), which became, “How to Start a Startup”. He suggested founders seek seed funding from “angel investors“, preferably those who had made money in technology. He half-jokingly added “but not me”, but, feeling guilty, he soon after organized Y Combinator to offer seed funding to startups.
From its inception to 2008, one program was held in each of the US cities of Cambridge, Massachusetts and Mountain View, California; in January 2009, Paul Graham announced that henceforth the Cambridge program would be closed and all future programs would take place in Silicon Valley .
 Notable portfolio companies
As of June 2009, Y Combinator had funded over 118   startups. The number of startups funded in each cycle has been gradually increasing. The first cycle in summer 2005 had eight startups. In the summer 2010 cycle, there were 36.
