The 2026 NatSec100 cohort collectively employs approximately 81,000 people nearly matching the 2025 cohort's total despite the loss of a few large organizations (SpaceX, Groq) from the 2025 cohort.
The NatSec100 punches well above its weight in the broader emerging defense tech workforce
The 2026 cohort accounts for nearly 67% of total headcount across all eligible VC-backed national security companies, up from roughly 57% in 2022. 2026 NatSec100 companies wield a median head count of 248, compared to 55 for remaining eligible companies. Hiring is concentrating at the top of the ecosystem, and the gap is widening. The companies with momentum are pulling the talent, the cleared workers, and the engineers that the rest of the field competes for.
Defense tech is bucking the broader labor market
The past year has been slow for U.S. job creation broadly, with hiring across the technology sector showing meaningful contraction. NatSec100 companies have continued to grow their workforces against that headwind.
The government side of the equation is moving in the opposite direction
While NatSec100 companies added headcount, the Department of War's civilian workforce shrank significantly. DOGE-driven reductions resulted in the termination of thousands of probationary employees beginning March 3, 2025, a department-wide civilian hiring freeze initiated February 28, 2025, and a Deferred Resignation Program that accelerated voluntary attrition. The Pentagon planned to reduce its civilian workforce by 50,000 or more, representing 5% to 8% of its roughly 900,000-person civilian base.
The same administration that is mandating faster procurement through the Warfighting Acquisition System, broader OTA use, and commercial-first acquisition is simultaneously shrinking the workforce responsible for executing those mandates. Contractors were advised to plan for delayed solicitations, slower proposal evaluations, and disrupted contract administration as a direct result of the personnel reductions.
Some agencies moved to course-correct. DISA flagged the need for "surgical rehiring" to fill mission-critical gaps. The Army's November 2025 acquisition reform consolidated authority under newly empowered Portfolio Acquisition Executives precisely to do more with fewer people. Whether those structural adjustments are sufficient to absorb the personnel loss without slowing the pace of innovation adoption is one of the more consequential open questions in the ecosystem.
“We need to invest in things that matter: technologies that strengthen economic resilience, expand scientific progress, reinforce democratic institutions, and create long-term societal value. As technologies of unprecedented power like AI, quantum computing, robotics and advanced semiconductors reshape the world, allied nations need to better align capital, talent, and policy to turn breakthroughs into real commercial and strategic advantage. While our adversaries move aggressively, democracies have a rare opportunity to lead together and shape a future that is more secure, prosperous, innovative, and grounded in broad human progress.”
