Pathbrite, a San Francisco-based startup behind a “Portfolio Learning Platform,” has raised $3.7 million from some very peculiar investors. Leading the round is Cengage Learning, which just came out from bankruptcy after reaching an agreement to eliminate billions of dollars in debt. “It’s a good signal that a company that has been forced to change a lot of its strategy has chosen us as its first investment” after coming out of bankruptcy, Hiles tells EdSurge. As part of the this deal, Pathbrite will be made available to students who use MindTap, an online learning platform from Cengage that is used in over 750 colleges.
