Furientis raises $25M from Benchmark to mass-produce low-cost missile interceptors

Furientis, a U.S. defense startup focused on mass-producing low-cost missile interceptors, has raised $25 million in a seed funding round led by Benchmark. The round values the company at $125 million and follows a $5 million pre-seed round earlier this year. Furientis aims to address critical shortages in the U.S. military’s missile supply with scalable and affordable manufacturing.

Seed funding and valuation

Furientis, a U.S.-based defense startup, has raised $25 million in a seed funding round led by Benchmark. The round values the company at $125 million, according to TechCrunch. This follows a $5 million pre-seed round announced in May.

Mission and military contract

Furientis is developing low-cost missile interceptors to address shortages in the U.S. military’s missile supply. The company has already secured a funded Pentagon contract to build mid-range interceptors, positioning it as a direct supplier to defense agencies.

The U.S. Navy currently receives only 300 to 500 interceptor missiles annually, a fraction of China’s reported production rate of 3,000 anti-ship cruise missiles per month. Furientis aims to close this gap by designing systems that can be assembled quickly from readily available components.

Manufacturing and testing

Furientis is targeting production of 1,000 systems per year at each of its factories. The company has been conducting field tests of its missiles on a bi-weekly basis, according to TechCrunch. Prototypes are tested at the White Sands facility in New Mexico.

The startup operates out of a facility in Los Angeles, where it designs and manufactures its systems.

Leadership and experience

Furientis was co-founded by Brody Franzen and Aris Simsarian, both of whom bring aerospace and defense engineering experience. Franzen previously served as deputy chief engineer at Virgin Galactic and later at Castelion, a defense startup. Simsarian led rocket engine testing at Virgin Orbit before joining Furientis.

The co-founders’ backgrounds reflect a focus on scalable manufacturing and rapid iteration, key to the company’s strategy.

Market context and competition

Furientis is part of a growing wave of startups aiming to disrupt traditional defense contracting with mass-produced, cost-effective systems. Competitors include larger defense startups like Anduril, Castelion, and Shield AI, as well as established contractors such as Raytheon and Lockheed Martin.

The U.S. military’s reliance on expensive, "exquisite" missiles—costing around $3 million each—has created an opening for startups promising more affordable alternatives.

Benchmark’s first defense bet

Benchmark’s investment in Furientis marks the venture capital firm’s first bet on a pure defense startup. General Partner Chetan Puttagunta is expected to join Furientis’ board, according to TechCrunch.

What this means

Lazyfounder analysis — our interpretation, not reported fact.

Furientis’ seed round—and Benchmark’s involvement—signals growing investor confidence in the defense tech sector, particularly for startups promising scalable, cost-effective alternatives to traditional defense contracting. The U.S. military’s urgent need for interceptor missiles creates a rare market opening, but Furientis will face intense competition from both startups and established contractors like Lockheed Martin and Raytheon.

For founders, this deal underscores how dual-use hardware (defense + commercial aerospace) can attract venture capital when backed by a clear procurement pathway. Benchmark’s participation also suggests that Silicon Valley’s traditional skepticism toward defense startups may be shifting, especially as geopolitical tensions drive demand for rapid innovation. Still, scaling production while maintaining affordability and reliability will be the real test.

Key takeaways

• Furientis has raised $25 million in a seed round led by Benchmark, with a $125 million valuation.
