Knewton has developed the industry’s most powerful adaptive learning engine, customizing educational content to meet the needs of each student. Whereas traditional classrooms and textbooks provide the same material to every student, Knewton dynamically matches lessons, videos, and practice problems to each student's ideal learning arc. Constant assessment across dimensions such as difficulty, frequency, and media maximizes learning efficiency and concept mastery. Knewton's GMAT prep, LSAT prep, and SAT prep courses bring the brightest and most experienced teachers directly to students worldwide via a live and on-demand online video classroom. Knewton was founded by Jose Ferreira, a former Kaplan executive, with funding from Accel Partners, Bessemer Venture Partners, First Round Capital, and prominent angel investors. The company was a finalist in the 2008 Amazon.com Start-Up Challenge and Digital Education Category Winner for the AlwaysOn Global 250 in 2009.
