Rule 1 Ventures

What Rule 1 Ventures does

Rule 1 Ventures is an early-stage venture capital firm headquartered in Atlanta that invests in seed to Series A aerospace and defense technology companies. Founded by former military officers Gary Buxton, a former Navy F/A-18F Naval Flight Officer and McKinsey consultant, and Todd Ehrlich, a Navy SEAL and two-time Inc. 500 CEO, the firm focuses on companies building technologies intended to define the future battlefield, including additive manufacturing, orbital energy infrastructure, autonomous systems, and software-defined defense manufacturing. The firm does not develop technology products itself; its offering is capital deployment combined with strategic advisory and domain expertise derived from its leadership and advisory board.

The firm's competitive position is anchored by its leadership team and advisory roster, which includes General Partner Admiral Sandy Winnefeld Jr., the former Vice Chairman of the Joint Chiefs of Staff; Venture Partner Will Harbin, a four-time exited Silicon Valley founder/CEO; and an advisory board comprising Gen. Ellen Pawlikowski (former Commander of Air Force Material Command), Gilman Louie (founder of In-Q-Tel), Kevin Hulbert (former CIA Chief of Station), former Congressman Mike Garcia, Adm. Wyman Howard (former Naval Special Warfare Development Group commander), and Jim Trowhill (former Accenture DoD Government Group Partner). This bench provides portfolio companies with procurement, intelligence community, and defense industrial base access that is difficult for generalist VCs to replicate.

As a venture capital firm, Rule 1 Ventures operates on a standard fund management revenue model: management fees on committed capital and carried interest on successful portfolio exits. Its distribution channel is direct investment sourcing via the founders' military networks and defense ecosystem events. The firm has executed notable investments in Roboze, an Italian additive manufacturing company expanding distributed manufacturing for aerospace, defense, and energy applications across the U.S., Europe, and the Middle East, and Mantis Space, an Albuquerque-based space and advanced energy startup developing orbital energy infrastructure, in which Rule 1 Ventures led an oversubscribed seed round exceeding $10 million in March 2026.

Direct peers

• Perceptive Ventures: Early-stage venture firm focused on aerospace, defense, and frontier technology. Similar fund size and stage profile to R1V, with comparable founder/ex-military orientation.
• Lux Capital: Early-stage venture firm with a deep focus on defense, aerospace, and dual-use technologies. Comparable to Rule 1 Ventures in targeting seed/Series A defense founders and leveraging technical credibility for deal flow.
• Shield Capital: Early-stage venture firm specifically focused on national security, defense, and intelligence-adjacent startups. Founded by former intelligence and DoD operators; the closest direct peer to Rule 1 Ventures in mandate and team profile.
• In-Q-Tel: Not-for-profit strategic investor for the U.S. intelligence community; invests in startups developing technologies for CIA/IC customers. Gilman Louie (R1V advisory board) co-founded In-Q-Tel, providing direct linkage between the two firms.
• 8VC: Early-stage venture firm with a strong defense and government technology investment thesis. Founded by Joe Lonsdale (Palantir co-founder), it competes with R1V for early-stage defense deals with similar operator-led model.
• Bedrock Capital: Early-stage venture firm focused on frontier technologies including defense, aerospace, and industrial innovation. Comparable in fund size and stage focus to R1V, with similar operator/technical orientation.

Broad incumbents

• Founders Fund: Large, established venture firm with a long-standing defense and deep-tech thesis (investments include Anduril, Palantir, SpaceX). Competes with R1V for defense tech deals but at meaningfully larger fund sizes and broader sector mandate.
• Andreessen Horowitz: Large multi-stage venture firm with an active American Dynamism practice covering defense, manufacturing, and public-sector tech. Overlaps with R1V's thesis but operates with vastly larger funds and broader LP base.
• General Catalyst: Large multi-stage venture firm that has built a growing defense and resilience practice. While not exclusively focused on defense, it competes with R1V for Series A/B defense tech rounds and brings institutional scale.
• Khosla Ventures: Large, established venture firm with deep-tech and frontier-technology exposure (including aerospace). Competes with R1V for hard-tech and aerospace deals though at larger scale and broader stage range.
