Andrei Kosogov is a Russian businessman and investor best known as a senior partner in Alfa Group, the conglomerate built by Mikhail Fridman and his partners, and as a co-founder of the international investment company LetterOne. He was born on 15 March 1961 in Estonia, which was then part of the Soviet Union.
He graduated from the Moscow Power Engineering Institute in 1987 with an engineering degree and began working at a small firm set up with the institute's help. He later earned an MBA from Harvard Business School.
Kosogov has been active in philanthropy and received Russia's Medal of Honour for charitable work related to childhood mental and neurological illnesses. Compared with the better known Alfa partners, he has kept a fairly low public profile, focusing on the group's investment and asset management side.
How Andrei Kosogov made his money
His big break came in 1992, when Mikhail Fridman hired him to oversee the setup of a privatization investment fund. Within months he became chief executive of Alfa Capital, and he went on to run much of the group's investment business. From November 2005 through June 2009 he chaired the supervisory board of Alfa-Bank Ukraine, and from November 2005 to April 2011 he chaired Alfa Asset Management. He sits on Alfa Group's supervisory board, is in charge of its investment units and chairs Altimo, its telecom arm, which oversaw the mobile operator VimpelCom.
In 2013 he co-founded LetterOne, which invested in oil and gas firm Wintershall Dea, mobile operators VimpelCom and Turkcell, and the health food chain Holland & Barrett. He stepped down from the LetterOne board in March 2022 after his partners were sanctioned by the European Union and the United Kingdom.
