201 Ventures

What 201 Ventures does

201 Ventures is a Madrid-headquartered venture capital firm founded in 2023 by Eric Slesinger, a former CIA officer. The firm invests at the pre-seed and seed stages exclusively in European defense technology startups, with a stated mission of advancing freedom and autonomy in Europe. Its $22 million fund, closed in 2025, is reported as one of the few American-led vehicles dedicated to this thesis.

The portfolio spans roughly 14 visible companies across multiple defense sub-verticals, including autonomous weapons systems (Stark, Delian Alliance Industries), hypersonic strike capabilities (Hypersonica), maritime defense (Zydro), counter-UAS (Polar Mist, Arctic R&D), intelligence tooling (Statecraft), and software-defined manufacturing for critical industries (Isembard, CX2). Notable positions include Stark Defence's €500 million round (2026, co-led by Sequoia and Founders Fund at a €3.5B+ valuation) and Hypersonica's €23.3 million Series A (2026).

The firm's revenue model is conventional venture capital: it earns management fees on committed fund capital and will realize carried interest upon successful portfolio exits. As a seed-stage specialist, returns are back-end weighted and dependent on acquisition or IPO outcomes of portfolio companies. The firm operates without disclosed co-investment partners or institutional backing beyond its own fund LPs, and its distribution mechanism is founder-led outreach within the European defense tech ecosystem, supplemented by participation in defense and VC industry events.

Direct peers

• Shield Capital: US-based early-stage venture capital firm exclusively focused on defense, intelligence, and national security startups. Directly comparable to 201 Ventures as a specialist defense tech seed investor, though with US rather than European geographic focus.
• Decisive Point: Early-stage venture capital firm investing in defense and national security technology companies. Closely comparable as a defense-tech-focused seed/early-stage specialist with thematic alignment to 201 Ventures' thesis.
• Lux Capital: Deep tech venture capital firm with a substantial portfolio of defense technology companies (e.g., Anduril, Hadrian). Comparable to 201 Ventures as a deep-tech investor with meaningful defense exposure, though Lux operates across broader frontier-tech sectors.
• Lavrock Ventures: Venture capital firm focused on hard-tech and national security startups. Directly comparable to 201 Ventures in defense tech specialization at the early stage, though Lavrock primarily invests in US-headquartered companies.
• In-Q-Tel: The CIA's strategic venture capital arm investing in technology relevant to national security. Highly comparable to 201 Ventures given founder Eric Slesinger's CIA background and the firm's national-security investment mandate.

Broad incumbents

• Andreessen Horowitz: Major US venture capital firm with the 'American Dynamism' thesis that explicitly includes defense tech. Comparable to 201 Ventures as a defense tech investor but operating as a broad incumbent across many sectors, not a specialist.
• Founders Fund: Major US venture capital firm with a long-standing track record of backing defense and frontier-tech companies (Palantir, SpaceX, Anduril). Co-led Stark's €500M round alongside 201 Ventures' portfolio investment; comparable as a defense-active incumbent.
• General Catalyst: Major US venture capital firm that has expanded into defense tech and participated in Hypersonica's Series A alongside 201 Ventures. Comparable as a defense-active incumbent but operating across a broad sector mandate.
• Sequoia Capital: Premier global venture capital firm that co-led Stark Defence's €500M round alongside 201 Ventures. Comparable as a defense-active incumbent but with a much broader investment mandate and far larger fund sizes.

Regional players

• Plural: European early-stage venture capital firm that led Hypersonica's Series A alongside 201 Ventures. Comparable as a European-region early-stage deep-tech investor but operating as a generalist across multiple sectors rather than a defense specialist.
