I run the Aquamarine Fund which is an investment partnership closely modelled on the original Buffett Partnerships, investing primarily in equities. In 2014 I published a book titled, “The Education of a Value Investor” which has sold more than 50,000 copies in English and has been translated into German, Spanish, Hebrew, Chinese, Japanese, Korean, Polish and Vietnamese amongst other languages. Investors in my fund include friends and family, high net worth individuals, their family offices, private banks investing on behalf of their clients and even some institutional investors and pension funds. One of my best learning experiences to date was my $650,000 lunch with Warren Buffett, on which Mohnish Pabrai and I successfully bid and won in 2007.Investors and business leaders that I admire include my father, Seth Klarman, Joel Greenblatt, Li Lu, John Mihaljevic, Thomas Edison, Mahatma Gandhi, Edward Shackleton, Marcus Aurelius, Anthony Robbins, Don Keough, Charlie Munger. My Investment process includes the using checklists – as was written up in Atul Gawande’s book, “The Checklist Manifesto”.
