STUDYBLUE kicks off the new year's funding season with a $9 million Series A-1 round led by Great Oaks Venture Capital, with the Wisconsin Alumni Research Foundation and previous investors participating. (It has now raised a total of $14.8 million since its founding in 2009.) The Madison, WI-based-startup provides a cloud platform that allows students to organize course materials and notes into online flashcards and quizzes that can be shared and studied on the go. The company boasts over 2.5 million users--1.5 million of them coming just last year alone--and 100 million study materials.) The service was initially aimed for college students, but as TechCrunch reports, it's gaining traction among high- and middle-schoolers.
