Summary
IronGate Capital Advisors, which describes itself as one of the most active defense technology venture capital firms in the United States, announced that its investment portfolio has grown to more than 540 companies across its two funds, according to a Business Wire release. The portfolio ranges from seed-stage start-ups to later-stage growth equity companies. The firm, founded in 2018, positions itself as a collaborative partner in the defense technology ecosystem and co-invests alongside many leading investors in the sector.

The milestone was announced at the "Strength Through Innovation Summit" in Washington, DC, hosted in collaboration with Stellar Ventures, a frequent co-investment partner and fellow defense technology VC firm. The two-day, invite-only event drew top officials from the defense, intelligence, and space communities, along with private-sector innovators and investors. The conference was co-sponsored by 15 companies, led by Albers Aerospace, AWS, Cooley, Delta Black, Stifel and Victory6. The event followed IronGate's "Founders Summit," held earlier in the year with ARLIS at the University of Maryland.

Several portfolio companies made announcements at the summit. Clearspeed secured a $60 million Series D round for its dual-use voice-based risk assessment technology. Delta Black announced the successful first flight of its Raider 330 Group 3 drone, which it said is designed to affect logistics and kinetic terrain in the INDOPACOM theatre. Atomic 6 presented Space Armor, a radome for space that protects satellites from debris and directed energy weapons while permitting radio frequency transmission. Skyfi showcased its Earth Intelligence platform, which delivers real-time information from space to government and commercial users.

Speakers included former U.S. Secretary of Defense Christopher C. Miller, who gave a keynote on the future of the national security landscape; Devin Nunes, Chairman of the President's Intelligence Advisory Board and CEO and Chairman of Trump Media & Technology Group; Major General Dennis Q. Bythewood, Special Assistant to the Chief of Space Operations at USSF; and Rt Hon Dr. Liam Fox, Chairman of the Abraham Accords Prosperity Group and former UK Secretary of State for Defence.

IronGate founding partner Ryan Morfin said, "We are in a tech arms race where speed, innovation, and capital allocation are decisive," adding that venture capital must act as a strategic partner to portfolio companies and the government. Celeste Ford, Managing Director at Stellar Ventures, said the firm added space as a central theme of the summit to accelerate America's most critical technologies. IronGate describes its focus as dual-use national security technologies in aerospace, defense, and intelligence.
