  Chief Accountant, Eric Branderiz 
  CFO, Jason Wheeler
  Treasurer and VP of finance, Susan Repo
  Sales chief, Jon McNeill
  Musk’s cousins, Lyndon and Peter Rive
  Autopilot lead, Chris Lattner
  VP of Autopilot, Jim Keller
  Battery executive, Kurt Kelty
  Diarmuid O’Connell, VP of business
  Matthew Schwall, Director of field performance
