Furientis manufactures interceptor missiles engineered from day one for high-rate production.

Defensive munitions
at scale can’t wait

In 2024, U.S. Navy ships fired hundreds of Standard Missiles defending against Red Sea threats, more than the nation can produce. This rate of interceptor consumption has only increased in recent months, leaving stockpiles at critical levels.

Since founding in early 2025, Furientis has been rapidly scaling to help close this gap.

F1.0 Tactical Interceptor

Furientis vertically integrates core subsystems including seeker, CAS, airframe and rocket motor. Manufacturability governs all design decisions from day one.

Propulsion

Proprietary solid rocket motor chemistry optimized for maximum production throughput, in a safe, proven packaging.

Airframe

Vehicle structures designed for determinate assembly to minimize final assembly time.

Controls

Canard controls enable extremely high maneuverability, compact packaging, and low actuation power.

Guidance

Cutting-edge software transforms commodity components into a highly differentiated and robust precision guidance stack.

About

Furientis was founded by lifelong rocket enthusiasts in May 2025. Their founding engineering team includes domain-level experts from the industry's fastest moving aerospace and defense companies.

Founders

Brody Franzen

CEO, Co-Founder

Brody’s interest in rockets began at the USC Rocket Propulsion Lab, the first student-led rocket to reach space. After this, he spent seven years at Virgin Galactic in Structural Design, Structural Test, and Deputy Chief Engineer roles. Most recently he spent a year at Castelion, where he was among the first engineering hires.

Aris Simsarian

Head of Propulsion, Co-Founder

Aris has been building solid rocket motors since age 9. In college he ran his university’s Rocket Lab, after which he spent five years at Virgin Orbit. During this time he served as Propulsion Test Engineer and later Head of Engine Test, where he led testing of engines producing 75,000 pounds of thrust. Prior to Furientis, he worked in systems test of electric VTOL aircraft at Supernal.
