EVEN ROBOTS NEED MONEY: Knewton, the New York startup behind adaptive learning technologies and, most recently, a “mind-reading” robot tutor, recently filed to raise $47.25 million in an SEC filing. The company has kept mum on details. Knewton has raised $105 million since it started in 2008—the last coming in a $51 million round led by London investor, Atomico in 2013.
