[NEWS]Seed round closed · Isengard in Y Combinator - Summer 2026UNCLASSIFIED // PUBLIC RELEASE

Combat-proven · Fielded in Ukraine

AI WEAPONS
OF MASS PRODUCTION.

Allied countries can build these weapons on their own soil. Isengard supplies the designs, autonomy stack, tooling and supply chain; your production cell builds AI-guided precision munitions at rate — close to the fight, and not dependent on imports.

Five aircraft and two in-house turbojets. Three systems are in combat use today; maturity is marked on every system.

Visual navigation system output - AI terrain matching in a GNSS-denied environment

Sovereign autonomy

It flies and strikes without GPS.

A vertically integrated stack - AES-256 encrypted datalink, visual navigation and AI targeting that hold precision in GNSS-denied, jammed environments.

Manufacturing model

Manufacturing across allied territory.

Design and manufacturing are integrated in-house, and production is placed close to the fight. Every airframe is built for tool-less assembly with low-specialization labor - which is what lets an allied partner stand up its own production cell instead of importing finished rounds.
