Zuckerberg, Moskovitz and some friends moved to Palo Alto, California, in Silicon Valley, where they leased a small house that served as an office. Over the summer, Zuckerberg met Peter Thiel, who invested in the company. They got their first office in mid-2004. According to Zuckerberg, the group planned to return to Harvard, but they eventually decided to remain in California. They had already turned down offers by major corporations to buy the company. In an interview in 2007, Zuckerberg explained his reasoning: "It's not because of the amount of money. For me and my colleagues, the most important thing is that we create an open information flow for people. Having media corporations owned by conglomerates is just not an attractive idea to me." The same year, speaking at Y Combinator's "Startup School" course at Stanford Univeristy, Zuckerberg made a controversial assertion that "young people are just smarter" and that other entrepreneurs should bias towards hiring young people.
