Redox raises $9 million.

Redox, a Madison software company, announced Tuesday that it has raised $9 million from investors.

The company, founded in 2014 by three former employees of Epic Systems, has developed a platform that makes it easier for applications to tie into systems for electronic health records.

The most recent round of financing was led by RRE Ventures and included existing investors .406 Ventures, HealthX Ventures and Flybridge Capital Partners.

Redox, which employs about 30 people, previously raised $3.5 million from venture capital firms in 2015.

The company’s software makes it easier for applications to exchange information with electronic health records, what is called “interoperability.”

Typically, that is a time-consuming chore because the systems for electronic health records are configured differently. As a result, the applications often have to be customized for each health system.

Redox’s platform bridges the two.

By connecting to its platform, a health system can have access to more than a hundred applications that require little or no tweaking.

At the same time, the health systems that are part of Redox’s network are a readymade market for application developers and save them from the potential chore of having to customize their applications for each customer.

Redox’s platform can exchange data with three dozen different vendors of electronic health records as well as work with other information systems, said George McLaughlin, Redox’s creative director.

“Redox has reached a key inflection point in attacking an enormous problem in health care,” Raju Rishi, general partner at RRE Ventures, said in a statement. “The proliferation of health care applications promises better data, better patient care and better outcomes.”
