Diamond Challenge
Competition · University of Delaware Horn Entrepreneurship · Online
Global business and social venture pitch competition for high school students.
Our take
Free pitch competition with $100,000 in total prizes. A real venture idea beats a clever one.
“Helps an application” is our read on how much an admissions reader is likely to weigh it: Strong means getting in or placing is a real achievement, Solid means it shows real interest and effort, and Light usually means most students who apply and pay can attend. It’s our opinion, not a ranking from any college, and a light one can still be a great summer.
