G ustavo Denegri is an Italian self-made billionaire with a successful career in the biotechnology and diagnostics industries. He is the chairman and controlling shareholder of DiaSorin, a major Italian multinational company that is a global leader in in-vitro diagnostics. He acquired the company and has been the driving force behind its growth into a global powerhouse.

DiaSorin specializes in developing and manufacturing the reagent kits used in immunodiagnostics and molecular diagnostics. The company's products are used in hospitals and laboratories around the world to test for a wide range of diseases and medical conditions. The company's value and Denegri's wealth surged dramatically during the COVID-19 pandemic, as DiaSorin became a major global supplier of tests for the virus. He has since passed on the CEO role but remains the chairman and largest shareholder of the publicly traded company.
