If you meant a different country’s version of Shark Tank (e.g., Australia, Canada, UK), let me know and I can provide that specific info.
Here’s the content regarding the who appeared in Shark Tank Season 4 (original U.S. version, aired 2012–2013).
In Season 4, the panel of regular sharks (Mark Cuban, Daymond John, Kevin O’Leary, Robert Herjavec, Lori Greiner) was joined by several guest investors.
