SHENZHEN -- Few technology entrepreneurs start even one company that reaches "unicorn" status, achieving a market valuation of $1 billion or more. Elon Musk has started three. Xiaomi's Lei Jun has built two.
Bill Gross has started and exited from seven unicorns and has another two in his active portfolio. Gross is the founder and chairman of Idealab, one of America's oldest and most successful technology incubators.
