Silent Ventures is an early-stage venture capital firm based in Dallas, Texas, founded in late 2022 by Jackson Moses. The solo-GP firm invests primarily at the concept, pre-seed, and seed stages in founders building aerospace, defense, national security, and deep tech companies. Its portfolio includes 14 disclosed defense and deep tech unicorns, among them Anduril, Saronic, Castelion, Hadrian, Armada, and Voyager Technologies (NYSE: VOYG). Silent Ventures closed an $85 million Fund II in 2026, anchored by GPx, the fund-of-funds vehicle run by Founders Fund Partner Emeritus Brian Singerman and Quiet Capital's Lee Linden.
Silent Ventures invests almost exclusively in aerospace, defense, national security, and adjacent deep tech companies, typically writing the first or largest check into a company at the pre-seed stage and then following on to co-lead or lead its seed round.
The firm concentrates capital in the highest-conviction names with follow on investments across subsequent rounds.
Silent Ventures explicitly does not apply "vice clause" investment restrictions common at some funds and is an active investor in kinetics and munitions companies, describing itself as a believer in the deterrent value of hard power alongside diplomacy.
Fund II plans to back 13 to 15 new companies, with a total of roughly 20 to 25 investments (inclusive of follow-ons) across that same company count.
Silent Ventures closed an $85 million Fund II earlier in 2026, the exact close date was not disclosed, and the launch was only announced publicly in August 2026.
The fund's anchor LP is GPx, a "fund of funds" vehicle co-founded in 2025 by Founders Fund Partner Emeritus Brian Singerman and Quiet Capital managing partner Lee Linden, which itself raised a reported $500 million first fund with backing from Peter Thiel.
GPx directs roughly 20% of its capital to backing emerging specialist VCs like Silent Ventures at the pre-seed and seed stage, reserving the remainder to co-invest alongside those managers in later-stage (Series B and beyond) rounds of their portfolio winners, an approach designed to let a specialist fund like
Silent Ventures keep participating in its breakout companies' later rounds without being diluted out or forced into ad hoc special purpose vehicles.
Other institutional backers of Fund II were not named.
Leadership
Silent Ventures operates as a solo-GP fund. Moses also founded and manages Silent Capital, a separate private syndicate offering members access to multi-stage defense and deep tech deals, and serves as a Senior Advisor to the founding teams of Castelion, Privateer, Long Wall, and Thor Dynamics.
Investment Strategy
Before founding Silent Ventures in late 2022, Moses founded and served as VP of Partnerships at MainStreet (acquired by Employer.com) and founded and served as Chairman & CEO of Spectrum AI (acquired by ActiveFence at a $137 million last valuation).
He has sourced deals for firms including 8VC, Founders Fund, a16z, Bessemer, Lightspeed, and NEA, and was named to Business Insider's Seed 100 list of top early-stage investors in 2024, 2025, and 2026.
Fund II's strategy leans on the firm's access to GPx's later-stage capital to stay in the cap tables of its winners as they graduate from early-stage rounds, rather than relying on outside special purpose vehicles.
