American Inventor

Janusz was the only inventor out of the four who completely threw out the ideas the ad agency pitched to him. Instead he went to the production company with his own, completely original idea for the ad. All of the other three contestants used the ad agency's ideas to some extent.

Perhaps under the presumption of equality, all four finalists went to the same advertising agency (DDB Worldwide) and production company (Plum Productions) to make their commercials.

Design companies that the inventors hired in this episode:
