Chegg

For becoming a social hub for homework help, course selection, note taking, and finding scholarships. Chegg began as “Netflix for textbooks,” but it has expanded its mission to being more of a student-centric network of useful services. Chegg has added online course scheduling; a college-admissions service that includes scholarship matching for high-school students; a web tutoring platform; and a lecture notes service to build out what it calls the “student graph.” The company has also built an HTML 5 e-textbook reader to anticipate the reduced use of physical volumes, and it claims more than one-million pageviews in its first two weeks.
