Shark Tank's Back! See the Show's Ingenious Pitches For Moms

Husband-wife duo Jordan Lloyd Bookey (the former head of K through 12 education at Google) and Felix Brandon Lloyd (Washington DC's educator of the year) pitched their company, Zoobean, in April 2014.

Jordan described the service as "Pandora for children's apps and books," combining input from expert curators with data to create a customized reading and learning library for your child based on his or her age, interests, and abilities.

Their pitch was a success, as Mark Cuban invested $250,000 for a 25-percent stake in the company.
