In addition, he holds shares in WOM, a Chilean telecommunications firm.Bjorgolfsson’s first fortune was made in post-soviet Russia. At a time when others perceived Russia to be tumultuous, he saw an underserved market that presented an exciting opportunity to invest in great ideas and businesses. He co-founded and developed Bravo Brewery, which produced beer and alcopops. Bravo became one of Russia’s premier brewing companies, particularly through its popular Botchkarov beer brand. Thor sold the business in 2002 to Heineken for $100 million.With the sale of Bravo, he was able to diversify his holdings by reinvesting in new ventures, focusing on telecommunications, pharmaceuticals, and banks. In a few years, he was able to turn that $100 million into a net worth of over $2.1 billion.A year after being featured on the 2007 cover of Forbes Magazine, Iceland went nearly bankrupt overnight and Thor found himself at the epicenter of the financial crisis. As a major shareholder in Landsbanki with personal guarantees of 350m euro, he refused to declare bankruptcy and eventually succeeded in paying off all of it. He then went on to invest in new businesses, re-establishing himself and being featured on the Forbes list of billionaires once again.During this time of rejuvenation, he wrote Billions to Bust and Back: How I Made, Lost and Rebuilt a Fortune, And What I Learned on the Way (2014). In the book, he shares his perspective of what it was like to be at the center of the storm and how he made it back to financial success.
