The story
SJSEE was formed in 2002 by former Sharks owners George Gund III and brother Gordon Gund. In October, 2011, the Gund's sold SJSEE to a group of local investors assembled by former Sharks president Greg Jamison which included Plattner, Kevin Compton, a partner at Kleiner Perkins, and Stratton Sclavos, former chairman and CEO of VeriSign. In 2014, Plattner purchased the ownership shares of both Compton and Sclavos and subsequently bought the remaining shares owned by former San Jose mayor Tom McEnery, E. Floyd Kvamme, and Harvey Armstrong to become the franchise’s majority owner.
Other former investors include former San Francisco 49ers player Brent Jones, venture capitalist Boots Del Biaggio, and former Brocade Communications Systems CEO Gregory Reyes. George Gund III maintained a minority stake in the team until his death in 2013.
