Each year, the TU Delft Impact Contest offers students the opportunity to further develop their own ingenious ideas, prototypes and research projects into business plans. The main goal and mission is to challenge students to come up with great innovative solutions to societal problems out-of-the-box, and translate them into real products and business plans.
