Austin Russell is on quite a run. The 28-year-old founder and CEO of Luminar, which develops vision-based lidar and machine perception technologies primarily for self-driving cars, told The Wall Street Journal earlier today that he is buying an 82% stake in Forbes Global Media Holdings in a deal that values the company at nearly $800 million. According to the WSJ, Russell's stake includes the remaining portion of the company owned by its namesake family, which sold 95% of the company to the Hong Kong-based investor group Integrated Whale Media back in 2014.
