GUARANTEACH

Guaranteach is an online math tutor. Powered by thousands of bite-size math videos on hundreds of different math topics, Guaranteach provides students with quick and easy access to a variety of explanations on any given math topic. Guaranteach's business model relies on community sourced videos, which are then screened by educational professionals to ensure that each video tutorial meets certain educational standards. Through this approach, the Guaranteach video library has content which... is not only broad - in that it covers many topics, but deep in that each topic is covered many times by different tutors. The proprietary software in the Guaranteach system learns the student's preferences over time and prioritizes video delivery to each student based on matching the video Guaranteach feels will be most effective in assisting the student. Guaranteach was founded in mid-2008 and was seed-funded by Innosight Ventures. The company raised a second round in December 2009 from the same investors. The company was acquired by Sophia Learning in 2011, which was in turn acquired by Capella University in 2012.More
