Katherine Boyle

Katherine Boyle (born ) is an American venture capitalist and journalist. Boyle has been a general partner at Andreessen Horowitz since 2022, leading its American Dynamism fund, which invests in technology companies serving the defense and civic technology markets.

Early life Katherine Boyle was born in Gainesville, Florida, the daughter of John and Donna Boyle. She competed in the 2003–2004 edition of the America's Junior Miss pageant, motivated by the competition's offer of scholarship money. Boyle's performance in the competition, including an original piano composition, won her the Florida state title.

University studies and journalism work Boyle studied government at Georgetown University, graduating in 2008. She wrote in a May 2008 editorial in The Hoya that her work in intellectual property during her Georgetown studies, combined with her Jesuit upbringing, had caused her to consider multiple serious moral issues. Following her graduation from Georgetown, Boyle was awarded a George J. Mitchell Scholarship to study Public Advocacy and Activism at the National University of Ireland, Galway.

Boyle worked as a reporter for The Washington Post in the early 2010s, covering culture. Boyle left the Post in 2014 to enroll in an MBA program at the Stanford Graduate School of Business. Boyle cold-emailed Thiel, who forwarded her correspondence to Trae Stephens, an early employee of Thiel's surveillance software company Palantir Technologies. Stephens had recently joined Founders Fund as a partner, and Boyle interned for Founders Fund in the summer of 2015, working on the firm's investments in defense technology startup companies. and has maintained a connection with him since. Vance's views on technology aligned with Boyle's, and she recalled in a 2025 interview that Vance was one of "only a handful of people saying these things in 2016 or 2017."

Boyle met Andreessen Horowitz partner David Ulevitch in 2019, as their respective firms competed for further investments in Anduril. The two firms eventually agreed to co-lead a Series B round in Anduril. and was appointed as the head of a new civic technology line of business in early 2021. Boyle moved to Miami to lead the business, intentionally placing herself outside of technology industry hubs such as the San Francisco Bay Area and Austin, Texas.

Work with Andreessen Horowitz Boyle departed General Catalyst in late 2021, and joined Andreessen Horowitz shortly afterwards. Margaux MacColl, writing for The Information, reported that Boyle's move to Andreessen Horowitz was motivated by her disagreement with General Catalyst's unwillingness to invest in automatic license-plate recognition company Flock Safety. According to Fortune, Boyle, who "runs the arm of a16z that invests in aerospace, defense, and infrastructure", is a co-founder of the American Dynamism fund. and also serves on the board of Anduril.

Boyle responded to questions about the ethics of her investment in military technology in a 2024 Fortune interview, where she argued that "It's making sure that the war of the future doesn't happen, and if it does happen, that it happens as quickly as possible or in as precise a way as possible."

Boyle detailed her views on family and technology in a February 2025 keynote speech at an American Enterprise Institute event, which was later was published in Tablet magazine. The AEI's journal The New Atlantis published a compilation of responses to her speech in its summer 2025 issue, featuring arguments from commentators including Christine Rosen and Patrick Deneen.

Rosen, senior editor of The New Atlantis and a senior fellow at the AEI, criticized Boyle's arguments about the intersection of technology and family values. Rosen "Unless and until we center human values and human virtues ... we are not having the conversations that matter. I hear little about human values and human virtues in Boyle's remarks, beyond her noting that families are important."

Deneen, a political theorist who taught Boyle in her undergraduate studies at Georgetown, argued that her thesis of technology aiding family values "elides recognition of how various technologies have arguably been more effective in undermining and even displacing the family than even the authoritarian regimes she rightly deplores." Deneen contrasted Boyle's philosophy with 20th-century sociologist Robert Nisbet's commentary on technology and social groups, and further argued that Boyle's proposed technological solutions "ultimately rely upon the assistance of the very state that she otherwise denounces as hostile to the family."

Military strategy analyst Seth G. Jones remarks that what Boyle is concerned about is not the lack of cutting-edge companies but the business climate and the government's procurement system.

William D. Hartung and Ben Freeman write that Boyle and her colleague Ulevitch position the private sector as "central players in shaping the future of the planet" and push for new-age militarism without safeguards.

Personal life Boyle described herself as a "practicing Catholic" in a 2021 interview. As of October 2025, she has two children and lives in the Miami metropolitan area.
