Richard Koch is an author and entrepreneur-investor. He not only writes books about how to achieve more, start new companies, make more money, and enjoy life more, but he also practises what he advocates. He was one of three founders of LEK, a noted international strategy consulting firm; and for the past thirty-seven years has invested in new and fast-growth companies, and compounded his money at an annual rate of twenty-two percent. By his own reckoning, he is now a sterling billionaire. The companies he has started or been a significant investor in include Filofax, the Belgo moules-frites chain, Plymouth Gin, Betfair, Auto1, and Fanduel. The concepts he has used to make money are described in this Financial Times Guide to Strategy, in The Star Principle, and in The 80/20 Principle, which has sold well over a million copies and been translated into forty languages. He is based in Gibraltar and also has homes in Cape Town, Australia, and Portugal.
