Afternoticing that gathering the study resources to prepare for your exams was very time-consuming, Marnix and three fellow students from Delft Technical University, founded StuDocu (StudeerSnel) in 2010. StuDocu is an online educational community where students can share study resources and answer each other's study-related questions. The platform is accessible by everyone, thereby making education available for anyone with an internet connection, anywhere in the world. Marnix’s mission is to build the global community for university students to excel in their studies and in life. Currently, he is well on his way to do so, with having more than 8 million students per month using StuDocu worldwide.
