Episode 403 – The Shark Investors and Entrepreneurs

The Shark Tank Episode 403 entrepreneurs will make their best pitch to the panel of five Shark investors who will use their own money if they choose to invest. The Shark Investors negotiate on the spot without any previous information, which differs from typical negotiations between venture capital investors and entrepreneurial start-ups.

Companies pitching the Shark Investors must go through a rigorous due diligence process before an on-air deal is completed. Shark Tank Blog follow ups help you keep track of the companies that end up successful and the ones that don’t complete their deal.

  1. The Sharks obviously do not always know the power of e-commerce, as is the case with the cloth diaper business Fuzzibunz. Cloth diapers are a HUGE market online. I will call out the owner of Fuzzibunz as a liar however, since she claims she invented the diaper–she copied the design and ran to be first to the patent. I was buying cloth diapers online before she ever started her business. I even contemplated buying some back in 2001. The ones I purchased were far better.
