Ion Țiriac is a Romanian businessman, the self-made billionaire Founder and President of Țiriac Group, a massive conglomerate spanning real estate, auto dealerships, and finance. His career is defined by his high-level success in sports, coaching, and pioneering post-Communist business.

Țiriac was an elite athlete: he played ice hockey for Romania at the 1964 Winter Olympics before becoming a top professional tennis player, winning the 1970 French Open men's doubles (alongside Ilie Năstase) and reaching the Wimbledon quarter-finals. After his playing career, he transitioned to management, becoming a successful coach and manager for top players like Boris Becker and Guillermo Vilas.

• Țiriac Group (Founder & President): The core private asset, a massive conglomerate in real estate, auto dealerships, insurance, and finance (founded in 1990).
• Sports Career: He was an Olympic ice hockey player, a French Open doubles winner (tennis), and a successful coach of Boris Becker.
• Pioneering Finance: He founded Banca Țiriac in 1990, Romania's first private bank after the fall of Communism.
• Tiriac Collection (Owner): His private museum of over 150 historic vehicles (including cars owned by Al Capone and Elton John).

Ion Țiriac's strategic genius was his decision to found Banca Țiriac in 1990, immediately after the fall of Communism, recognizing the immense, untapped opportunity in private financial services. The bank grew into UniCredit Țiriac Bank (one of the largest banks in Romania). He aggressively diversified into auto dealerships (TiriacAuto), auto leasing, insurance (Allianz-Țiriac), and real estate (Țiriac Holdings).

He also developed and owned the major ATP masters tennis tournament, the Mutua Madrid Open (2009–2021). Elected to the International Tennis Hall of Fame in 2013, Țiriac became the first Romanian billionaire in 2007. His wealth is secured by the long-term, stable returns generated by his essential financial and auto retail empire, which he built from the ground up after his sports career ended.

Ion Țiriac's social impact is structural, stemming from his pioneering role in establishing private financial services (banking and insurance) in post-Communist Romania, which was foundational to the nation's economic transition. His company provides thousands of stable jobs in essential sectors.

His structural contribution is also cultural and sports-related: his ownership and development of the Mutua Madrid Open and his extensive classic car collection (Țiriac Collection, exhibiting over 150 historical vehicles) enrich global sports and cultural heritage.

Ion Țiriac maintains the distinguished, authoritative style of a European magnate and former athlete. His attire is consistently formal and high-quality, favoring tailored suits. His aesthetic reflects stability and immense financial power, befitting his status as a national economic pioneer.

Residing in Romania, his luxury is the immense security and financial reward derived from his multi-billion dollar fortune. His life is dedicated to strategic investment, asset diversification, and his passion for historic cars and tennis.
