Curtis Guy Yarvin (born June 25, 1973) is an American software engineer, political theorist, and blogger best known by his pseudonym Mencius Moldbug. He gained prominence in the late 2000s as a founder of the neoreactionary movement (also known as the Dark Enlightenment), alongside philosopher Nick Land. This anti-egalitarian and anti-democratic ideology critiques modern liberal democracy, advocating for alternatives like sovereign corporations or monarchic governance structures. Yarvin's writings, primarily through his blog Unqualified Reservations (2007-2013), explored themes of political philosophy, history, and technology, influencing segments of the far-right and tech libertarian communities. Professionally, Yarvin has worked as a software developer at companies like Sun Microsystems and Dow Jones. In 2013, he founded the software project Urbit, a decentralized personal server platform, which operates under the company Tlon. His ideas have increasingly intersected with mainstream conservative politics, with reported influence on figures like Peter Thiel and JD Vance. Yarvin's work remains controversial, often criticized for promoting authoritarian and racially tinged views, though he has distanced himself from explicit white nationalism. By the early 2020s, his neoreactionary thought had permeated discussions in Silicon Valley and Republican circles, underscoring his impact on networks of influence in technology and politics.
