OM1

Scale Venture Partners headed the round, which comes roughly a year and a half after OM1's $21 million Series B.

Bruce Greenstein, the chief technology officer at the Department of Health and Human Services for the past year, has stepped down from his post to return to the private sector.

Boston-based health outcomes and tech company OM1 has just announced that it raked in $21 million in a Series B financing round led by Polaris Partners with participation from existing investors including General Catalyst and 7wire Ventures.
