The Fourth Law
Overview
The Fourth Law is a Ukrainian defense technology company founded in 2023 by entrepreneur Yaroslav Azhnyuk. Based in Kyiv, the company focuses on developing scalable autonomy solutions for defense-related UAVs (unmanned aerial vehicles) and FPV (first-person view) drones. TFL has raised an undisclosed amount from a group of venture capital funds and private investors based in the U.S., Canada, and the European Union to support its innovative AI-driven advancements in drone technology.
Recent Developments
- July 2025: The Fourth Law announced its first round of investments from venture funds and angel investors in the EU, USA, and Canada. This funding round will help scale the company’s innovative autonomous systems for FPV drones.
- July 2025: TFL revealed its flagship product, the TFL-1 autonomy module, which grants drones the ability to execute missions autonomously in their final flight phases, surmounting barriers like electronic warfare.
- Ukrainian FPV drones equipped with TFL-1 modules are actively used on the battlefield, particularly by Ukraine’s 58th Separate Motorized Infantry Brigade, demonstrating efficiency in overcoming radio-electronic interference.
- The Fourth Law is working on further extending the operational range and autonomy of its UAVs, with new capabilities expected to be demonstrated by the end of 2025.
- Ukrainian defense initiatives continue their support and collaboration with TFL under the Brave1 government project, focusing on enhancing Ukrainian defense technology competencies amid ongoing territorial conflict.
- As of March 2025, discussions with global defense entities continue as TFL seeks to introduce its technology into broader international markets, including working with NATO-aligned defense sectors as the legal framework adapts to exporting Ukrainian defense tech innovations.
