Exogenesis Corp., a gas cluster ion beam (GCIB) technology firm in Billerica, has raised $4.5 million in an equity offering filed with the U.S. Securities and Exchange Commission on Monday.
The regulatory filing is an amendment to one the company made in June that noted Exogenesis’ $3.7 million offering of a planned $4.1 million financing. Although no backers were listed in the filing, Exogenesis does note its investors on its website – Inflection Point Ventures, Venture Capital Fund of New England and JDS Uniphase Corp., as well as individual backers.
The privately held company, founded in 2005, uses the GCIB technology to process implantable medical devices, according to the Exogenesis website. The company has developed the ClusterCoat Processing System, used in surface coating medical devices by changing the physical and chemical properties of the atomic layers of a surface.
Exogenesis’ core technology, GCIB, was first developed in the 1990s at Kyoto University’s Ion Beam Engineering Experimental Laboratory, with further development conducted at Epion Corp. in the U.S.
