Meet Brian
Brian MacCarthy founded and leads Booz Allen Ventures, the company’s corporate venture capital arm. In this role, he directs investments in early-stage dual-use startups and helps America’s warfighters and mission teams benefit from new technologies faster.
Booz Allen Ventures, which launched in 2022 under Brian’s leadership, invests in and brings to market companies focused in AI, cyber, defense tech, quantum, space, and reindustrialization. Under his direction, Booz Allen Ventures has made 18 investments and tripled the size of the fund to $300 million from $100 million. The portfolio showcases several of the top startups and innovators in the Silicon Valley Defense Group (SVDG) NatSec 100 that streamline government workflows, build space infrastructure, enable warfighting decision support in austere environments, and build the future of advanced autonomous capabilities.
In previous Booz Allen roles, Brian led the creation of the company’s Helix Center for Innovation; spearheaded the largest hackathon series inside the Department of War, winning numerous awards—including the Secretary of the Navy’s highest honor—and enabling Pentagon customers to accelerate prototyping; and expanded the company’s capacity to help federal healthcare customers achieve mission goals. Brian also led the Booz Allen Tech Scouting team starting in 2015, sourcing early recommendations and tech across the venture ecosystem and delivering research insights to federal decision makers. Prior to joining Booz Allen, he performed management roles in business development and product marketing.
Brian serves on the boards of Reveal Technologies, Scout AI, Hidden Level, Credo AI, RAIC Labs, Latent AI, Second Front Systems, Firestorm, and the nonprofit Globally. In addition, he regularly contributes to industry analysis of defense tech, via SVDG; venture investment strategy; and leading global venture trends in China.
