Gustavo Denegri

Gustavo Denegri is the chairman of biotech company Diasorin; nearly all of his wealth comes from his 45% stake in the company. In 2000, his private equity firm acquired the distressed DiaSorin from American Standard Companies and built it into a global player in diagnostics. His first breakthrough came when his Gruppo Pro-Ind, a components firm, merged with Piaggio, owner of motor scooters Vespa and Aprilia. He is one of few Italian businessmen to have built billion-dollar companies in more than one sector. His firm Investimenti is run by his son Michele and has a diverse portfolio, including medical technology, real estate and TV production.
