Beyond the Tank

Barbara Corcoran visits her most successful investment and gives a pep talk; Daymond John becomes the customer of a business that didn't receive Shark funding; and a check-in with a company that produces a successful scratch-free sponge.

Mark Cuban checks in on a beauty product investment he made during season 4; Daymond John doesn't see eye-to-eye with an investment partner and wonders if they will continue their business partnership; a pet product inventor tries to get his invention into the marketplace without a Shark's guidance; and a man who nearly bankrupted his luggage business invests Shark Lori Greiner's money in a product he knows does not meet with her approval.

Lori Greiner checks on her investment of The Paintbrush Cover, a convenient way to store wet paintbrushes from Season Five, and throws a curveball into attempts to take their business to the next level. Robert Herjavec meets with Mark and Hanna Lim, the couple who invented the Lollacup to understand why their sales have stalled and how they can be re-ignited. And despite not getting an investment from the sharks, entrepreneur Liz Holtz still finds success with her gluten-free cookies.
