Tim Phillips is a longtime conservative activist and political strategist known for his leadership in libertarian and free-market advocacy. Born in 1969, he rose to prominence as President of Americans for Prosperity (AFP), a major nonprofit organization funded by the Koch brothers' network, serving in that role from 2006 to 2021. Under his tenure, AFP expanded its grassroots operations significantly, mobilizing millions of activists and playing a pivotal role in the Tea Party movement during the late 2000s and early 2010s. The organization focused on opposing government spending, regulations, and initiatives like the Affordable Care Act, influencing Republican electoral strategies and policy debates at both state and federal levels.

Prior to leading AFP, Phillips built a career in conservative politics, including roles as a political consultant and fundraiser. He worked for the Republican National Committee and served as executive director of the Club for Growth, a group advocating for lower taxes and limited government. His early involvement in Christian conservative causes and campaign work shaped his approach to issue-based advocacy. After stepping down from AFP in 2021, Phillips transitioned to advisory positions within the Koch network's broader ecosystem, including affiliations with organizations like the State Policy Network, and has continued to engage in strategic consulting for conservative initiatives aimed at economic policy reform.

Phillips's influence extends through his network of donors, activists, and policymakers, positioning him as a key figure in mapping conservative influence operations. He has been involved in high-profile efforts to shape public opinion on fiscal conservatism, though his work has drawn criticism from progressives for its ties to dark money in politics.
