Broad Street Angels just picked ZSX Medical for its first investment

Newly minted angel investor group Broad Street Angels — chaired by Ben Franklin’s RoseAnn Rosenthal and based out of the Union League — has officially backed their first horse.

ZSX Medical, the medical device company working on a rapid surgical closure technology, received an investment in the six-figure range. No other details from the deal were disclosed. The company was founded in 2009 and is based out of PLEXUS, that healthcare coworking space on Drexel University stomping grounds.

Founded by Dan Mazzucco, a Dartmouth grad with a background in the medical device industry, we last spotted the company behind another big check: it secured $100,000 at the annual expo of the Keiretsu Forum, another angel investors group.

Rosenthal said the company first presented at the group’s initial deal review meeting in January. She was “a little surprised” at how quickly the deal came together.

“That our members invested in a company from our first day of reviewing presentations underscores our motivation and commitment to make things happen, and to be recognized as a serious member of the mid-Atlantic region’s angel investment community,” Rosenthal said in a statement.
