Y Combinator is a seed accelerator that provides financing services and business consulting to startup companies. In its main program, Y Combinator interviews and selects two batches of companies per year. The companies receive seed money, advice, and connections in exchange for 7% equity. The program includes "office hours", where startup founders meet individually and in groups with Y Combinator partners for advice. Founders also participate in weekly dinners where guests from the Silicon Valley ecosystem (successful entrepreneurs, venture capitalists, etc.) speak to the founders.
