The Penn Wharton Entrepreneurship program just held its annual Startup Challenge (formerly the Wharton Business Plan Competition). Thirty teams of entrepreneurial hopefuls were winnowed down to just eight finalists, who competed to win the alumni judges’ hearts and minds and garner a total of $135,000 in cash and business services during the Startup Showcase on Penn’s Campus last week.

Three of the startups featured medical innovations, including an early-detection test for chemotherapy-related infections, an implant to help prevent blindness, and a method for weeding out non-emergency 911 calls. Other concepts included a modern spin on an ancient Indian skincare ritual, and a way to keep fruit from spoiling to help reduce food shortages.

Each finalist presented to the judges and took their follow-up questions. The judges hailed from companies including King Circle Capital, Karlin Asset Management, The Charian Group, Monetate, ExamWorks Group, and OraSure. They were charged with considering six categories: idea, product/service, preparation for launch, execution plan, traction and team.

In addition to formal presentations to the judges, the eight finalists performed two-minute elevator pitches to compete for the $3,000 Michelson People’s Choice Award. The pitches were streamed online so a digital as well as live audience could vote.
