The New York National Security Forum (NYNSF) is an annual, application-only gathering that connects defense-technology founders with the acquisition executives, government stakeholders, investors, and financial leaders involved in developing and deploying military capabilities. Scheduled for September 28–29, 2026, at Apella in New York City, the Forum is designed for a cohort of approximately 150 participants.

Its focus is helping defense innovation move beyond prototypes toward operational use and sustained production. The two-day program examines how companies can meet warfighter needs, navigate government acquisition, scale manufacturing, and secure the capital needed to grow. Sessions include keynote conversations, panel discussions, capability showcases, structured matchmaking, and networking opportunities.

Topics span defense acquisition, supply chains, production capacity, mission-ready intelligence, electronic-spectrum sensing, contracting pathways, defense investment, and acquisition reform. The Forum brings founders, military and government acquisition leaders, operators, and investors into direct conversation about current capability needs and the challenges of fielding new technology. Proceedings follow the Chatham House Rule, and sessions are not recorded.
