Alexander Leonidovich Mamut, born in 1960 in Moscow, Russia, is an influential financier, lawyer, and diversified investor whose interests span banking, real estate, media, and technology. His family background is intellectual; his father was a prominent lawyer who specialized in commercial law.

Mamut followed his father’s legal path, graduating in 1982 with a degree in Law from the prestigious Moscow State University. This high-level legal training equipped him with the intellectual rigor and strategic understanding required to navigate the complex privatization and corporate legal frameworks that defined Russia’s economic transition in the 1990s. His career rapidly moved from law into finance and asset management, leveraging his legal foundation for high-stakes deal-making.

Alexander Mamut's career is a masterclass in strategic maneuvering and high-stakes financial deal-making. In 1990, he co-founded the law firm ALM Consulting, leveraging his expertise during the rise of private capital. He quickly moved into banking, co-founding the Business and Cooperation Bank (KMB) in 1991, and later joining the leadership of the National Reserve Bank.

His defining move has been his role as a versatile, opportunistic 'corporate fixer' and serial investor across distressed or undervalued assets. Mamut acquired and sold major stakes in a dizzying array of sectors: copper, coal, internet companies ('Rambler Group'), retail, and real estate. A notable consolidation came through his holding company, A&NN Investments, which controlled interests in sectors like Polymetal International (precious metals) and major retail chains. His immense wealth is a reflection of his uncanny ability to enter, restructure, and profitably exit large-scale, complex corporate deals.

Alexander Mamut's philanthropy is largely channeled toward cultural preservation, arts, and media, reflecting his sophisticated background in Moscow's intellectual circles.

• Cultural Patronage: He is a major supporter of the arts, often funding exhibitions and cultural initiatives, including those connected to his former media holdings.
• Educational Support: He contributes to educational institutions and has been a member of the advisory board for the Moscow School of Management SKOLKOVO.

His primary civic impact lies in stabilizing key Russian media and Internet assets during periods of volatility, ensuring the continuity of these platforms for public consumption. His approach is that of a private patron who strategically invests in the nation's intellectual and commercial infrastructure.
