CENGAGEMENT: New year, new beginnings. Fresh from exiting bankruptcy, Cengage is back in action and ready to re-engage. BostInno has details on the the publisher's partnership with Boston edtech hub, LearnLaunch, which includes an undisclosed investment in the LearnLaunch Accelerator, which has graduated 13 startups to date. (The third cohort begins in early February.) Details on the agreement are scant, other than the fact that Cengage will provide mentorship and host events to Beantown's community of edtech entrepreneurs.
