The Fourth Law, makers of massively scalable AI systems for FPV drones, announces its first round of funding and unveils its flagship product TFL-1
For the first time, the company is showcasing a video of the widespread battlefield deployment of AI-guided targeting and products - TFL-1 autonomy module and the Lupynis-10-TFL-1 UAV, designed to empower every single drone with a crucial, primary level of autonomy.
Kyiv, Ukraine; 10 July 2025 – The Fourth Law (TFL / Четвертий Закон), a defense tech company headquartered in Kyiv, Ukraine today announced that it raised an undisclosed amount of funding from a group of venture funds and angel investors based in the EU, USA, and Canada. The company's first products, the TFL-1 autonomy module, and the Lupynis-10-TFL-1 UAS (daytime or nighttime) — increase the success of FPV drone missions by a factor of 2-5 times, while increasing their cost by just 10-20%. This becomes possible by transferring the control over the drone in its last 500 meters of flight to an onboard computer running AI algorithms. The Ukrainian Defense Forces use the products in volumes, as it helps them solve the issues related to electronic warfare, radio horizon limitations, while enhancing their pilots’ precision capability.
Following several years of R&D and rigorous testing with the Armed Forces of Ukraine, TFL successfully pioneered a unique, multi-level artificial intelligence system. It is engineered to precisely identify and categorize targets, whether stationary or moving, ensuring high-precision strikes.

The company’s Founder and CEO, Yaroslav Azhnyuk, said: “Massively scalable drone autonomy is the single most important defense technology of this decade. There’s no one on the planet who understands this better than the Ukrainian Defense Forces. We’re doing the most important work of our lives, and the funding we’ve raised from the investors is an invaluable catalyst to the growing defensive capabilities of the Free World. We will need, however, much more resources to deliver on the full potential of this technology. We must make sure that the adversaries of democracy and freedom won’t get there faster.”
Colonel Ruslan Shevchuk, Commander of the 58th Motorized Infantry Brigade of the Armed Forces of Ukraine, noted: “Since March 2025, pilots of the 58th Separate Motorized Infantry Brigade have been utilizing aircraft equipped with the TFL-1 system, which has demonstrated its effectiveness on the battlefield during this period. It helps us overcome electronic warfare, jamming, acquire, and strike targets in challenging conditions. Its capabilities are most notably demonstrated during special missions. Our operational experience confirms it as a truly effective system.”
Since its founding in 2023, The Fourth Law has released TFL-1, a massively manufacturable and low-cost module providing any FPV drone with state-of-the-art terminal guidance and cruise capabilities. Engineered for mass deployment, the TFL-1 is designed to achieve production volumes of hundreds of thousands of units monthly. Its cost-effectiveness ensures that this vital technology can be integrated into every FPV drone, enabling rapid scaling and over the air updates. In addition, the company ships Lupynis-10-TFL-1: both as an unmanned aerial vehicle (UAV), i.e., a singular drone, and an unmanned aerial system (UAS) consisting of a hundred 10-inch FPV drones with TFL-1 autonomy, a ground control station, and support equipment.

These drones are capable of reaching targets within 30 kilometers with a payload of 1 kg, and a maximum payload of 3.5 kg at shorter distances. Aside from the Lupynis platform, TFL-1 is integrated in over a dozen major FPV manufacturers’ drones. The company offers Lupynis-10-TFL-1 UAS to the Government and Defense Forces while the TFL-1 module, through licensing, is available to other FPV manufacturers. Сodified and certified, TFL products are in use by the Government of Ukraine and numerous units in the Ukrainian Defense Forces.
The Fourth Law is an autonomous robotics company built on a thesis that by 2030, autonomous robots will be disrupting trillion-dollar industries, including in defense, transportation, agriculture, and construction. TFL vision for full and massively scalable autonomy for defensive FPV drones assumes five stages of autonomy:
Terminal guidance
Terminal guidance for bombing
Target detection and engagement
GPS-denied navigation
Autonomous take-off and landing
Once that is achieved, second-order products become possible and viable for the modern military requirements, including drone swarms and nests, drone carriers, and fully autonomous interceptors of drones of different types.

The software stack enabling autonomy, which starts with tooling such as simulation and analytical software and ends with autonomous applications and fleet management systems is relatively easy to transfer between the platforms – from quadcopters to fixed wing UAVs, missiles, ground and sea drones. This functionality is fully independent of satellite navigation system (GNSS) access. The experience is further transferable to the civil use domains outside of defense, including but not limited to logistics, manufacturing, and construction.
The recent funding and increased adoption rate establish The Fourth Law as one of the leaders in the growing space of massively scalable robotic autonomy, with a particular application in the defense space.
