The "tech surge" to repair ObamaCare's broken enrollment website involves employees from Oracle and Google with ties to the administration.
The Centers for Medicare and Medicaid Services (CMS) disclosed a handful of companies and individuals involved in the effort for the first time in a blog post Thursday.
The two are working with HealthCare.gov contractors QSSI and CGI Federal, respectively, to help boost the site's performance.
In its post, CMS also said workers from Oracle and Red Hat were on hand to provide expertise.
"These dozens of people are straightening and reinforcing the team we have working 24/7 to address the problems around HealthCare.gov," wrote CMS communications Julie Bataille.
Until Thursday, the administration had provided virtually no details about the "tech surge," a special effort launched on Oct. 21 to fix the botched enrollment portal.
Bataille's blog post was notable for including names and companies but otherwise short on specifics.
It is still unclear whether the White House sought independent talent from the tech world or drew solely from a pool already affiliated with the administration.
Dickerson and Gershman both have past Obama ties, according to their LinkedIn profiles, working on President Obama's 2012 campaign and as a Presidential Innovation Fellow, respectively.
