Founded in 2011 by Chiew Farn Chung (CEO), Edward Middleton (CTO), and Yee Whye Teh (CSO), ClassDo is an online education marketplace powered by a virtual classroom where anyone can teach and learn. Before you say “meh” and click away, give this demo link a try. ClassDo’s virtual classroom doesn’t require any software installation. Everything runs seamlessly in the browser, which is neat. It has a collaborative whiteboard that allows teachers and students to view and take notes in real time. Even the page flips are synced between student and teachers.
