Philadelphia-based accelerator Dreamit Health has announced the 15 health startups that will join its next accelerator class.

As in previous years, the accelerator is sponsored by Penn Medicine and Independence Blue Cross, but this year, Dreamit Health also added medical device company Zimmer Biomet as a partner. The larger number of startups in Dreamit’s cohort this year is the result of a $325,000 Blackstone Innovation Grant that the accelerator received in February.

Earlier this year, Dreamit Health made a few changes to its accelerator. The accelerator announced that in its next class, it will offer the startups the option to keep their equity if they do not accept cash from the program. Dreamit Health said they added this option in order to get later stage companies and serial entrepreneurs to participate.

Dreamit Health used to take an 8 percent equity stake in its accelerator companies. In exchange, companies got $50,000 in seed funding with a possible $250,000 in follow-on funding, as well as other benefits: free workspace, mentorship, legal advice and counsel, and access to healthcare personnel at Penn Medicine and Independence. Moving forward, those startups who choose not to give up their equity will still get those other benefits.
