Benchmark Backs Defense Startup Furientis With $25M for Low-Cost Interceptors

Silicon Valley venture capital firm Benchmark has led a $25 million seed round in defense startup Furientis, marking the storied firm's first direct bet on a pure defense tech company. The investment propels the one-year-old Los Angeles-based startup to a $125 million valuation. Furientis, which previously secured $5 million in pre-seed funding, aims to mass-produce low-cost missile interceptors to replenish heavily strained Western stockpiles and has already secured a funded Pentagon contract for mid-range systems.

Traditional high-end missile interceptors can cost upwards of $3 million each, posing severe sustainability challenges during modern conflicts. Furientis co-founder Brody Franzen warned of an alarming capacity imbalance, noting that the U.S. Navy receives only 300 to 500 interceptors annually, while China reportedly produces around 3,000 anti-ship cruise missiles each month. "We’re being outproduced by a factor of 100 plus," Franzen stated. "That is why we started the company." Benchmark general partner Chetan Puttagunta praised the startup's rapid operational execution, emphasizing that Furientis had already developed functional prototypes and conducted test launches with initial funding.

Founded by Franzen, a former Virgin Galactic deputy chief engineer, and Aris Simsarian, who previously directed rocket engine testing at Virgin Orbit, Furientis avoids the long, costly development cycles typical of traditional defense primes like Lockheed Martin and Raytheon. Instead of matching peak exquisite performance, the startup designs interceptors using readily available commercial components, running field tests every two weeks and conducting trial launches at the White Sands facility in New Mexico.

Furientis plans to eventually scale output to 1,000 interceptor units per year at each factory location. The company joins a growing cohort of defense disruptors, including Anduril, Castelion, and Shield AI, competing to secure lucrative Pentagon production contracts as Western militaries scramble to build affordable, high-volume defenses against adversary drone and missile threats.
