Tyler Hassen’s forthcoming memoir provides an insider account of his 11-month stint with Elon Musk’s Department of Government Efficiency, or DOGE, portraying the initiative as a fast-moving attempt to apply private-sector management practices to the federal government. Hassen joined after a screening process that began with an unexpected trip to a SpaceX office and an assignment to develop two to five Department of Commerce ideas for Musk. He was later deployed to the Department of the Interior, where he became acting assistant secretary of policy, management and budget under Doug Burgum and worked 14-hour days until November. Hassen defends DOGE’s aims despite its failure to achieve Musk’s $2 trillion savings target and findings from the Government Accountability Office that DOGE’s savings figures were flawed. He says the project brought the federal deficit into public debate, while acknowledging that its speed, secrecy and weak communications contributed to its loss of control over the narrative, lawsuits, layoffs and an eventual split between Musk and President Donald Trump. The memoir, titled "Inside DOGE: The Real Story from a Senior Insider," also recounts Hassen’s work reviewing contracts and grants, his role in registering the Gulf of America name, threats against him and his family, and how his first experience with AI at DOGE led to his new role at Zone Frontier.
