Defense Tech Fundraising: Active VCs, DoD & Non-Dilutive

How to raise venture capital for a defense, dual-use, or national security startup in 2026.

How to Raise Venture Capital for a Defense Tech Startup

Defense tech is now a mainstream venture category — Anduril, Shield AI, Palantir, Skydio, Saronic, and Hadrian have proven that dual-use and defense-first companies can build durable multi-billion-dollar businesses. The category has its own investor community, its own non-dilutive capital stack (SBIR, DIU, AFWERX, STRATFI/TACFI, OTA), and its own path to revenue (Program of Record, FMS, coalition partners).

Why defense tech is a distinct fundraising category

Defense buyers move on 3–10 year procurement cycles, with distinct funding stages (SBIR Phase I/II/III, OTA, Program of Record, FMS). Founders who understand the acquisition lifecycle and the non-dilutive capital stack can extend runway by 12–36 months and de-risk equity rounds materially.

The category also has security constraints — export controls (ITAR, EAR), facility clearance (FCL), personnel clearance, and CMMC compliance — that shape hiring, capital structure, and cap table (foreign investor restrictions).

The most active defense and dual-use VCs

Defense-first leaders: Founders Fund (American Dynamism), Andreessen Horowitz American Dynamism, Lux Capital, 8VC, General Catalyst, Point72 Ventures, Shield Capital, Marlinspike, Razor's Edge Ventures, Scout Ventures, Countdown Capital, and Silent Ventures.

European and allied defense specialists: NATO Innovation Fund, Project A (dual-use), Balderton (dual-use), Lakestar, Vsquared, Expeditions Fund, Twin Path Ventures, and MD One. Corporate defense CVCs: Lockheed Martin Ventures, RTX Ventures, Boeing HorizonX, Northrop Grumman Ventures, BAE Systems, and Booz Allen Ventures.

The DoD non-dilutive capital stack

SBIR Phase I ($50K–$300K feasibility), Phase II ($1M–$2M prototype), Phase III (sole-source production contracts). AFWERX and SpaceWERX Open Topic solicitations, STRATFI ($3M–$15M) and TACFI ($1M–$5M) matching programs for graduated SBIR companies, and DIU Commercial Solutions Openings for dual-use technologies.

Additional programs: Army xTechSearch, Navy NavalX, DARPA (small business awards), DoE ARPA-E for dual-use energy, DHS S&T, and the newer Office of Strategic Capital (OSC) loan guarantee program for hardware and critical technology companies.

OTA, Program of Record, and revenue pathways

Other Transaction Authority (OTA) contracts through consortia (DIU, TReX, S2MARTS, C5, MD5) let startups move from prototype to production without going through FAR-based procurement. Prototype OTA can transition to production OTA (up to $500M), which can then move into a Program of Record for durable multi-year revenue.

Foreign Military Sales (FMS) and Direct Commercial Sales (DCS) to allied nations (NATO, AUKUS, Japan, Korea, Israel, UAE, Saudi Arabia) can extend TAM 2–5x beyond US-only revenue.

How defense deals are typically structured

Standard NVCA templates at seed and Series A. Defense-specific terms often include CFIUS/FIRRMA reps, foreign ownership control and influence (FOCI) covenants, ITAR/EAR compliance, and facility clearance maintenance. Foreign LP concentration limits are common — funds with meaningful foreign LP exposure may be excluded from cap tables of classified programs.

Founder vesting is standard. Cap table hygiene is critical — a single foreign passive minority investor can block SAP or SCI-level programs later.

Common mistakes when raising for defense tech

Ignoring non-dilutive capital — $2M–$10M of SBIR + STRATFI + OTA can extend runway by 12–24 months and materially de-risk the Series A. Accepting foreign capital without CFIUS review — cleaning up the cap table later is expensive and slow. Pitching pure commercial VCs without a dual-use commercial thesis — most Tier 1 VCs still want a commercial anchor, not pure DoD dependency.

Frequently asked questions

Which are the most active defense tech VCs in 2026?
Founders Fund (American Dynamism), a16z American Dynamism, Lux Capital, 8VC, General Catalyst, Point72 Ventures, Shield Capital, Marlinspike, Razor's Edge Ventures, Scout Ventures, Countdown Capital, Silent Ventures, and NATO Innovation Fund are the most active lead investors.
How much non-dilutive capital can a defense startup realistically stack?
$2M–$10M is achievable in the first 18–24 months through SBIR Phase I ($50K–$300K), Phase II ($1M–$2M), AFWERX/SpaceWERX Open Topics, STRATFI ($3M–$15M), TACFI ($1M–$5M), and DIU CSOs. This can extend runway 12–24 months and materially de-risk the Series A.
What is the difference between OTA and FAR-based contracts?
Other Transaction Authority (OTA) contracts move faster, allow flexible IP terms, and let non-traditional defense contractors participate without complex FAR compliance. Prototype OTA can transition directly to production OTA (up to $500M) without recompete, then to a Program of Record.
Should I accept foreign investors?
Carefully. Foreign passive minority investors can trigger CFIUS review under FIRRMA and can block later access to SAP/SCI-level programs. Screen every investor for CFIUS risk. Some defense VCs strictly limit foreign LP concentration in their own funds for this reason.
Do I need facility clearance and personnel clearances at Series A?
Not usually at seed or Series A, but you need a credible path to FCL and CMMC compliance. Investors expect a clear roadmap. Many defense startups sponsor early employees for Secret or TS clearance in year 1–2 to unlock classified program access.
