402 FUND, USA

While a first-year student at Columbia Business School, Ian Jacobs, a former associate at Goldman Sachs, did what many business school students do: pen a letter to Warren Buffett. The important difference: Buffett not only wrote back, but was so impressed that he invited Ian to come work for him that summer. That was the beginning of a nearly 6 year relationship where Ian worked at Berkshire Hathaway on investment research and other projects as directed by Buffett. In 2009 Ian launched the 402 Fund. The limited partnership, concentrated and long-only, focuses on businesses with an identifiable structural competitive advantage.
