Dona Bertarelli

Dona Bertarelli, sister of Ernesto Bertarelli, inherited a fortune when the family biotech business, Serono, was sold in 2007 for $9 billion. In the 1990s, Dona was the company's executive director of public and professional affairs. Since Serono's sale, she has entered into business ventures of her own, including Spindrift Racing, a sailing racing stable she founded in 2011 with her long-term partner Yann Guichard. The enterprise won the Rolex Fastnet race in 2013, and broke the record for the America Discovery Route, which is a cross-Atlantic race that replicates the journey of Christopher Columbus. Alongside Ernesto, Dona chairs the Bertarelli Foundation. Through her Ledunfly family office, she is also creating a collection of luxury resorts, including a new eco-toursim destination in the Exuma district of the Bahamas. She is already the owner of the Country Club Geneva and the Grand Hotel Park in Gstaad and recently acquired the Five Seas Hotel in Cannes.
