Edtech startup Quick Key Mobile, maker of a quiz grading app for teachers, has announced it has raised $100,000 in Seed funding. Investors include ARC Capital Development and additional unnamed investors. The app, which is currently available for iOS, enables instructors to upload a quiz template for paper-based exams, and then use a smartphone camera to scan the quizzes and get results through the app. The team originally raised funds via Kickstarter last year, when it secured just over $20,000. The Cambridge, Massachusetts-based company was founded in 2012 by teacher Walter O. Duncan and Isaac Van Wesep.
