You can see a list of names below but, as usual, Musk is leaning on top lieutenant Steve Davis to help run DOGE along with Brad Smith, a health care executive who founded Russell Street Ventures. (Vivek Ramaswamy, the technology entrepreneur who was supposed to co-lead DOGE, is out and running for governor of Ohio.)

Fortune‘s list is not all encompassing. The people associated with DOGE are ever-changing and new execs pop up every day. Several venture capitalists are involved with or advising DOGE including A16z’s Marc Andreessen and Shaun Maguire, a partner of Sequoia Capital. Musk has also unleashed an army of young engineers, who we respectfully call the “nerd squad,” who, along with more senior staff, have helped take control of several agencies, including the Office of Personnel Management, General Services Administration, and the Treasury Department’s payment system.

Like many Musk companies, DOGE and the White House were not forthcoming with information and did not respond to our requests for comment. Fortune relied on news reports, government documents and filings, as well as social media posts including LinkedIn and X, to compile its list of executives. We attempted to contact everyone.
