Winnick earned the bulk of his wealth on the sale of $734 million worth of Global Crossing stock nearly 20 years ago. He now serves as chairman of Winnick & Co., and got into the live-streaming business in 2017, when he acquired a majority stake in concert service Qello for an undisclosed amount – a position he exited at year’s end with a sale to Canada-based Stingray, also on undisclosed terms. Winnick & Co. also invests in industries such as telecommunications, digital media, health care and real estate.
It took Winnick just two and a half years to become a billionaire between founding his company and selling off his stock. Global Crossing went public a year after it was founded, at a $4.5 billion valuation. Winnick has been largely quiet since cashing out, other than serving as chairman of Winnick Family Foundation. Winnick’s wife, Karen, is a children’s book author. The two support a number of environmental, animal-rights, health care and Jewish causes. The couple lives in the 1930s Bel Air estate built by Conrad Hilton.
