Boston-based Healthrageous, which spun out of Partners Health Care in 2008, has announced a $6.5 million second round of funding from North Bridge Venture Partners, Egan-Managed Capital, Long River Ventures, and an undisclosed investor. The health coaching platform company has now raised more than $15 million in funding, including a $6 million first round of funding, which it announced in 2010 at the time it rebranded from HopSkipConnect. The same three investors participated in that first round.

Healthrageous plans to use the funds to enhance its user interfaces (both on the web and through its mobile app), analytics engines, and machine learning platform. The company expects this to make the program more personalized for users. Healthrageous' offerings aims to help users prevent and self-manage chronic conditions by incorporating goal setting, health journey maps, gaming dynamics, biometric feedback, and interactive digital coaching that includes inspirational messages, challenges, trackers, reminders, and more.

When Healthrageous first came out of beta its sales strategy appeared to be appealing directly to employers, while this still appears to be a key customer group for the company it has also begun working through health plans like Highmark, which is sponsoring a six-month trial at Acosta Sales and Marketing, a self-insured company in Jacksonville, Florida, for diabetes self-management. That pilot leverages Healthrageous' partnership with Telcare for its cellular-enabled glucose meters.

MobiHealthNews caught up with Healthrageous CEO Rick Lee just a few weeks ago to discuss the company's strategy and Highmark pilot -- revisit that interview here.
