Björgólfur Thor

Björgólfur Thor Björgólfsson (born 19 March 1967), known as Björgólfur Thor, also known internationally as Thor Bjorgolfsson, and colloquially in Iceland as Bjöggi, is an Icelandic businessman and entrepreneur. He is also chairman and founder of Novator Partners. Björgólfur Thor has built and invested in a number of larger companies and smaller startups, including Actavis, a pharmaceutical company; WOM Play - mobile telecoms challenger brands in Chile, Colombia and Poland; and Zwift - an online platform for indoor cycling.

Björgólfur Thor was the first Icelander to join Forbes magazine's list of the world's richest people in 2005. He has been declared as "Iceland's first billionaire"; and was ranked as the 249th-richest person in the world by Forbes magazine in 2007 - up from 350th the previous year - with a net worth of $3.5 billion.

However, due to the financial crisis of 2007–2010, he lost much of his fortune and faced personal bankruptcy. He worked out a complex deal with his creditors to pay off his debts while holding on to his key investments. Björgólfur Thor published an autobiography in 2014 about the ordeal titled 'Billions to Bust and Back'. He reappeared on the Forbes rich list in 2015 with a net worth of $1.3 billion, and as of August 2023 had a net worth of $2.5 billion.
