Philadelphia-based digital health accelerator DreamIt Health has announced its third class. As in previous years, the accelerator is sponsored by Penn Medicine and Independence Blue Cross.

DreamIt Health takes an 8 percent equity stock in accelerator companies. In exchange, companies get $50,000 in seed funding with a possible $250,000 in follow-on funding, as well as other benefits: free workspace in the University Science Center's Innovation Center, mentorship, legal advice and counsel, and access to healthcare personnel at Penn Medicine and Independence. Companies will participate in a 16-week course that ends in October.

"One of the most valuable things an entrepreneur can do early on is talk to a lot of customers," Steve Barsh, EVP of Accelerators and Managing Director for DreamIt Health, said in a statement. "DreamIt Health companies are encouraged and coached on how to quickly identify and test critical assumptions with potential customers from day one. Having Independence and Penn Medicine as strategic partners opens up doors and unique opportunities for our entrepreneurs and enables them to quickly test those assumptions that can make or break a company."

In addition to eight official accelerator participants, DreamIt will incubate two ideas that have sprung from employees at the Children's Hospital of Philadelphia, with whom DreamIt has a partnership. One group is exploring simulated driving assessments to improve the driving skills of hospital employees, while the other will integrate DNA and RNA tumor profiling to improve molecular cancer analytics. Read on for the eight accelerator participants:
